Note that this will pull in some long - * math routines (pun intended!) and thus make your executable noticeably - * longer. Likewise with 'PRINTF_LONG_LONG_SUPPORT' for the long long - * specifier, and with 'PRINTF_SIZE_T_SUPPORT' for the size_t specifier. - * - * The memory footprint of course depends on the target CPU, compiler and - * compiler options, but a rough guesstimate (based on a H8S target) is about - * 1.4 kB for code and some twenty 'int's and 'char's, say 60 bytes of stack - * space. Not too bad. Your mileage may vary. By hacking the source code you - * can get rid of some hundred bytes, I'm sure, but personally I feel the - * balance of functionality and flexibility versus code size is close to - * optimal for many embedded systems. - * - * To use the printf, you need to supply your own character output function, - * something like : - * - * void putc ( void* p, char c) { while (!SERIAL_PORT_EMPTY) ; - * SERIAL_PORT_TX_REGISTER = c; } - * - * Before you can call printf, you need to initialize it to use your character - * output function with something like: - * - * init_printf(NULL,putc); - * - * Notice the 'NULL' in 'init_printf' and the parameter 'void* p' in 'putc', - * the NULL (or any pointer) you pass into the 'init_printf' will eventually - * be passed to your 'putc' routine. This allows you to pass some storage - * space (or anything really) to the character output function, if necessary. - * This is not often needed but it was implemented like that because it made - * implementing the sprintf function so neat (look at the source code). - * - * The code is re-entrant, except for the 'init_printf' function, so it is - * safe to call it from interrupts too, although this may result in mixed - * output. If you rely on re-entrancy, take care that your 'putc' function is - * re-entrant! - * - * The printf and sprintf functions are actually macros that translate to - * 'tfp_printf' and 'tfp_sprintf' when 'TINYPRINTF_OVERRIDE_LIBC' is set - * (default). Setting it to 0 makes it possible to use them along with - * 'stdio.h' printf's in a single source file. When 'TINYPRINTF_OVERRIDE_LIBC' - * is set, please note that printf/sprintf are not function-like macros, so if - * you have variables or struct members with these names, things will explode - * in your face. Without variadic macros this is the best we can do to wrap - * these function. If it is a problem, just give up the macros and use the - * functions directly, or rename them. - * - * It is also possible to avoid defining tfp_printf and/or tfp_sprintf by - * clearing 'TINYPRINTF_DEFINE_TFP_PRINTF' and/or - * 'TINYPRINTF_DEFINE_TFP_SPRINTF' to 0. This allows for example to export - * only tfp_format, which is at the core of all the other functions. - * - * For further details see source code. - * - * regs Kusti, 23.10.2004 - */ - -#ifndef _BSP_PRINTF_H -#define _BSP_PRINTF_H - -#include -#include - -/* Global configuration */ - -/* Set this to 0 if you do not want to provide tfp_printf */ -#ifndef TINYPRINTF_DEFINE_TFP_PRINTF -#define TINYPRINTF_DEFINE_TFP_PRINTF 1 -#endif - -/** - * Set this to 0 if you do not want to provide - * tfp_sprintf/snprintf/vsprintf/vsnprintf - */ -#ifndef TINYPRINTF_DEFINE_TFP_SPRINTF -#define TINYPRINTF_DEFINE_TFP_SPRINTF 1 -#endif - -/** - * Set this to 0 if you do not want tfp_printf and - * tfp_{vsn,sn,vs,s}printf to be also available as - * printf/{vsn,sn,vs,s}printf - */ -#ifndef TINYPRINTF_OVERRIDE_LIBC -#define TINYPRINTF_OVERRIDE_LIBC 0 -#endif - -/* Optional external types dependencies */ - -/* Declarations */ - -#if defined(__GNUC__) -#define _TFP_SPECIFY_PRINTF_FMT(fmt_idx, arg1_idx) \ - __attribute__((format(printf, fmt_idx, arg1_idx))) -#else -#define _TFP_SPECIFY_PRINTF_FMT(fmt_idx, arg1_idx) -#endif - -#ifdef __cplusplus -extern "C" { -#endif - -typedef void (*putcf)(void*, char); - -/** - * 'tfp_format' really is the central function for all tinyprintf.

- *
- * An interrupt safe version of the API function that receives a discrete
- * message from a message buffer.  Messages can be of variable length and are
- * copied out of the buffer.
- *
- * ***NOTE***:  Uniquely among FreeRTOS objects, the stream buffer
- * implementation (so also the message buffer implementation, as message buffers
- * are built on top of stream buffers) assumes there is only one task or
- * interrupt that will write to the buffer (the writer), and only one task or
- * interrupt that will read from the buffer (the reader).  It is safe for the
- * writer and reader to be different tasks or interrupts, but, unlike other
- * FreeRTOS objects, it is not safe to have multiple different writers or
- * multiple different readers.  If there are to be multiple different writers
- * then the application writer must place each call to a writing API function
- * (such as xMessageBufferSend()) inside a critical section and set the send
- * block time to 0.  Likewise, if there are to be multiple different readers
- * then the application writer must place each call to a reading API function
- * (such as xMessageBufferRead()) inside a critical section and set the receive
- * block time to 0.
- *
- * Use xMessageBufferReceive() to read from a message buffer from a task.  Use
- * xMessageBufferReceiveFromISR() to read from a message buffer from an
- * interrupt service routine (ISR).
- *
- * @param xMessageBuffer The handle of the message buffer from which a message
- * is being received.
- *
- * @param pvRxData A pointer to the buffer into which the received message is
- * to be copied.
- *
- * @param xBufferLengthBytes The length of the buffer pointed to by the pvRxData
- * parameter.  This sets the maximum length of the message that can be received.
- * If xBufferLengthBytes is too small to hold the next message then the message
- * will be left in the message buffer and 0 will be returned.
- *
- * @param pxHigherPriorityTaskWoken  It is possible that a message buffer will
- * have a task blocked on it waiting for space to become available.  Calling
- * xMessageBufferReceiveFromISR() can make space available, and so cause a task
- * that is waiting for space to leave the Blocked state.  If calling
- * xMessageBufferReceiveFromISR() causes a task to leave the Blocked state, and
- * the unblocked task has a priority higher than the currently executing task
- * (the task that was interrupted), then, internally,
- * xMessageBufferReceiveFromISR() will set *pxHigherPriorityTaskWoken to pdTRUE.
- * If xMessageBufferReceiveFromISR() sets this value to pdTRUE, then normally a
- * context switch should be performed before the interrupt is exited.  That will
- * ensure the interrupt returns directly to the highest priority Ready state
- * task.  *pxHigherPriorityTaskWoken should be set to pdFALSE before it is
- * passed into the function.  See the code example below for an example.
- *
- * @return The length, in bytes, of the message read from the message buffer, if
- * any.
- *
- * Example use:
-
-// A message buffer that has already been created.
-MessageBuffer_t xMessageBuffer;
-
-void vAnInterruptServiceRoutine( void )
-{
-uint8_t ucRxData[ 20 ];
-size_t xReceivedBytes;
-BaseType_t xHigherPriorityTaskWoken = pdFALSE;  // Initialised to pdFALSE.
-
-    // Receive the next message from the message buffer.
-    xReceivedBytes = xMessageBufferReceiveFromISR( xMessageBuffer,

-    {
-        // A ucRxData contains a message that is xReceivedBytes long.  Process
-        // the message here....

-
-    // If xHigherPriorityTaskWoken was set to pdTRUE inside
-    // xMessageBufferReceiveFromISR() then a task that has a priority above the
-    // priority of the currently executing task was unblocked and a context
-    // switch should be performed to ensure the ISR returns to the unblocked
-    // task.  In most FreeRTOS ports this is done by simply passing
-    // xHigherPriorityTaskWoken into taskYIELD_FROM_ISR(), which will test the

- *

- *
- * Note 3:  An additional 4 bytes of RAM is required for each space in a every

SemaphoreHandle_t xSemaphoreCreateRecursiveMutexStatic( StaticSemaphore_t *pxMutexBuffer )

- *
- * Creates a new recursive mutex type semaphore instance, and returns a handle
- * by which the new recursive mutex can be referenced.
- *
- * Internally, within the FreeRTOS implementation, recursive mutexs use a block
- * of memory, in which the mutex structure is stored.  If a recursive mutex is
- * created using xSemaphoreCreateRecursiveMutex() then the required memory is
- * automatically dynamically allocated inside the
- * xSemaphoreCreateRecursiveMutex() function.  (see
- * http://www.freertos.org/a00111.html).  If a recursive mutex is created using
- * xSemaphoreCreateRecursiveMutexStatic() then the application writer must
- * provide the memory that will get used by the mutex.
- * xSemaphoreCreateRecursiveMutexStatic() therefore allows a recursive mutex to
- * be created without using any dynamic memory allocation.
- *
- * Mutexes created using this macro can be accessed using the
- * xSemaphoreTakeRecursive() and xSemaphoreGiveRecursive() macros.  The
- * xSemaphoreTake() and xSemaphoreGive() macros must not be used.
- *
- * A mutex used recursively can be 'taken' repeatedly by the owner. The mutex
- * doesn't become available again until the owner has called
- * xSemaphoreGiveRecursive() for each successful 'take' request.  For example,
- * if a task successfully 'takes' the same mutex 5 times then the mutex will
- * not be available to any other task until it has also  'given' the mutex back
- * exactly five times.
- *
- * This type of semaphore uses a priority inheritance mechanism so a task
- * 'taking' a semaphore MUST ALWAYS 'give' the semaphore back once the
- * semaphore it is no longer required.
- *
- * Mutex type semaphores cannot be used from within interrupt service routines.
- *
- * See xSemaphoreCreateBinary() for an alternative implementation that can be
- * used for pure synchronisation (where one task or interrupt always 'gives' the
- * semaphore and another always 'takes' the semaphore) and from within interrupt
- * service routines.
- *
- * @param pxMutexBuffer Must point to a variable of type StaticSemaphore_t,
- * which will then be used to hold the recursive mutex's data structure,
- * removing the need for the memory to be allocated dynamically.
- *
- * @return If the recursive mutex was successfully created then a handle to the
- * created recursive mutex is returned.  If pxMutexBuffer was NULL then NULL is
- * returned.
- *
- * Example usage:
- 
- SemaphoreHandle_t xSemaphore;
- StaticSemaphore_t xMutexBuffer;
-
- void vATask( void * pvParameters )
- {
-    // A recursive semaphore cannot be used before it is created.  Here a

SemaphoreHandle_t xSemaphoreCreateCounting( UBaseType_t uxMaxCount, UBaseType_t uxInitialCount )

- *
- * Creates a new counting semaphore instance, and returns a handle by which the
- * new counting semaphore can be referenced.
- *
- * In many usage scenarios it is faster and more memory efficient to use a
- * direct to task notification in place of a counting semaphore!
- * http://www.freertos.org/RTOS-task-notifications.html
- *
- * Internally, within the FreeRTOS implementation, counting semaphores use a
- * block of memory, in which the counting semaphore structure is stored.  If a
- * counting semaphore is created using xSemaphoreCreateCounting() then the
- * required memory is automatically dynamically allocated inside the
- * xSemaphoreCreateCounting() function.  (see
- * http://www.freertos.org/a00111.html).  If a counting semaphore is created
- * using xSemaphoreCreateCountingStatic() then the application writer can
- * instead optionally provide the memory that will get used by the counting
- * semaphore.  xSemaphoreCreateCountingStatic() therefore allows a counting
- * semaphore to be created without using any dynamic memory allocation.
- *
- * Counting semaphores are typically used for two things:
- *
- * 1) Counting events.
- *
- *    In this usage scenario an event handler will 'give' a semaphore each time
- *    an event occurs (incrementing the semaphore count value), and a handler
- *    task will 'take' a semaphore each time it processes an event
- *    (decrementing the semaphore count value).  The count value is therefore
- *    the difference between the number of events that have occurred and the
- *    number that have been processed.  In this case it is desirable for the
- *    initial count value to be zero.
- *
- * 2) Resource management.
- *
- *    In this usage scenario the count value indicates the number of resources
- *    available.  To obtain control of a resource a task must first obtain a
- *    semaphore - decrementing the semaphore count value.  When the count value
- *    reaches zero there are no free resources.  When a task finishes with the
- *    resource it 'gives' the semaphore back - incrementing the semaphore count
- *    value.  In this case it is desirable for the initial count value to be
- *    equal to the maximum count value, indicating that all resources are free.
- *
- * @param uxMaxCount The maximum count value that can be reached.  When the
- *        semaphore reaches this value it can no longer be 'given'.
- *
- * @param uxInitialCount The count value assigned to the semaphore when it is
- *        created.
- *
- * @return Handle to the created semaphore.  Null if the semaphore could not be
- *         created.

- * Create a new task and add it to the list of tasks that are ready to run.
- *
- * Internally, within the FreeRTOS implementation, tasks use two blocks of
- * memory.  The first block is used to hold the task's data structures.  The
- * second block is used by the task as its stack.  If a task is created using
- * xTaskCreate() then both blocks of memory are automatically dynamically
- * allocated inside the xTaskCreate() function.  (see
- * http://www.freertos.org/a00111.html).  If a task is created using
- * xTaskCreateStatic() then the application writer must provide the required
- * memory.  xTaskCreateStatic() therefore allows a task to be created without
- * using any dynamic memory allocation.
- *
- * See xTaskCreateStatic() for a version that does not use any dynamic memory
- * allocation.
- *
- * xTaskCreate() can only be used to create a task that has unrestricted
- * access to the entire microcontroller memory map.  Systems that include MPU
- * support can alternatively create an MPU constrained task using
- * xTaskCreateRestricted().
- *
- * @param pvTaskCode Pointer to the task entry function.  Tasks
- * must be implemented to never return (i.e. continuous loop).
- *
- * @param pcName A descriptive name for the task.  This is mainly used to
- * facilitate debugging.  Max length defined by configMAX_TASK_NAME_LEN - default
- * is 16.
- *
- * @param usStackDepth The size of the task stack specified as the number of
- * variables the stack can hold - not the number of bytes.  For example, if
- * the stack is 16 bits wide and usStackDepth is defined as 100, 200 bytes
- * will be allocated for stack storage.
- *
- * @param pvParameters Pointer that will be used as the parameter for the task
- * being created.
- *
- * @param uxPriority The priority at which the task should run.  Systems that
- * include MPU support can optionally create tasks in a privileged (system)
- * mode by setting bit portPRIVILEGE_BIT of the priority parameter.  For
- * example, to create a privileged task at priority 2 the uxPriority parameter
- * should be set to ( 2 | portPRIVILEGE_BIT ).
- *
- * @param pvCreatedTask Used to pass back a handle by which the created task
- * can be referenced.
- *
- * @return pdPASS if the task was successfully created and added to a ready
- * list, otherwise an error code defined in the file projdefs.h
- *

- * This function differs from vTaskDelay () in one important aspect:  vTaskDelay () will

- * 								void * pvTimerID,
- * 								TimerCallbackFunction_t pxCallbackFunction );
- *
- * Creates a new software timer instance, and returns a handle by which the
- * created software timer can be referenced.
- *
- * Internally, within the FreeRTOS implementation, software timers use a block
- * of memory, in which the timer data structure is stored.  If a software timer
- * is created using xTimerCreate() then the required memory is automatically
- * dynamically allocated inside the xTimerCreate() function.  (see
- * http://www.freertos.org/a00111.html).  If a software timer is created using
- * xTimerCreateStatic() then the application writer must provide the memory that
- * will get used by the software timer.  xTimerCreateStatic() therefore allows a
- * software timer to be created without using any dynamic memory allocation.
- *
- * Timers are created in the dormant state.  The xTimerStart(), xTimerReset(),
- * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
- * xTimerChangePeriodFromISR() API functions can all be used to transition a
- * timer into the active state.
- *
- * @param pcTimerName A text name that is assigned to the timer.  This is done
- * purely to assist debugging.  The kernel itself only ever references a timer
- * by its handle, and never by its name.
- *
- * @param xTimerPeriodInTicks The timer period.  The time is defined in tick
- * periods so the constant portTICK_PERIOD_MS can be used to convert a time that
- * has been specified in milliseconds.  For example, if the timer must expire
- * after 100 ticks, then xTimerPeriodInTicks should be set to 100.
- * Alternatively, if the timer must expire after 500ms, then xPeriod can be set
- * to ( 500 / portTICK_PERIOD_MS ) provided configTICK_RATE_HZ is less than or
- * equal to 1000.
- *
- * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
- * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter.
- * If uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
- * enter the dormant state after it expires.
- *
- * @param pvTimerID An identifier that is assigned to the timer being created.
- * Typically this would be used in the timer callback function to identify which
- * timer expired when the same callback function is assigned to more than one
- * timer.
- *
- * @param pxCallbackFunction The function to call when the timer expires.
- * Callback functions must have the prototype defined by TimerCallbackFunction_t,
- * which is	"void vCallbackFunction( TimerHandle_t xTimer );".
- *
- * @return If the timer is successfully created then a handle to the newly
- * created timer is returned.  If the timer cannot be created (because either
- * there is insufficient FreeRTOS heap remaining to allocate the timer
- * structures, or the timer period was set to 0) then NULL is returned.
- *
- * Example usage:
- * @verbatim
- * #define NUM_TIMERS 5
- *
- * // An array to hold handles to the created timers.
- * TimerHandle_t xTimers[ NUM_TIMERS ];
- *
- * // An array to hold a count of the number of times each timer expires.
- * int32_t lExpireCounters[ NUM_TIMERS ] = { 0 };
- *
- * // Define a callback function that will be used by multiple timer instances.
- * // The callback function does nothing but count the number of times the
- * // associated timer expires, and stop the timer once the timer has expired
- * // 10 times.
- * void vTimerCallback( TimerHandle_t pxTimer )
- * {
- * int32_t lArrayIndex;
- * const int32_t xMaxExpiryCountBeforeStopping = 10;
- *
- * 	   // Optionally do something if the pxTimer parameter is NULL.
- * 	   configASSERT( pxTimer );
- *
- *     // Which timer expired?
- *     lArrayIndex = ( int32_t ) pvTimerGetTimerID( pxTimer );
- *
- *     // Increment the number of times that pxTimer has expired.
- *     lExpireCounters[ lArrayIndex ] += 1;
- *
- *     // If the timer has expired 10 times then stop it from running.
- *     if( lExpireCounters[ lArrayIndex ] == xMaxExpiryCountBeforeStopping )
- *     {
- *         // Do not use a block time if calling a timer API function from a
- *         // timer callback function, as doing so could cause a deadlock!

- * @param xTimer The handle of the timer that is having its period changed.
- *
- * @param xNewPeriod The new period for xTimer. Timer periods are specified in

- * that has been specified in milliseconds.  For example, if the timer must
- * expire after 100 ticks, then xNewPeriod should be set to 100.  Alternatively,
- * if the timer must expire after 500ms, then xNewPeriod can be set to

- *
- * @param pxHigherPriorityTaskWoken The timer service/daemon task spends most
- * of its time in the Blocked state, waiting for messages to arrive on the timer
- * command queue.  Calling xTimerChangePeriodFromISR() writes a message to the
- * timer command queue, so has the potential to transition the timer service/
- * daemon task out of the Blocked state.  If calling xTimerChangePeriodFromISR()
- * causes the timer service/daemon task to leave the Blocked state, and the
- * timer service/daemon task has a priority equal to or greater than the
- * currently executing task (the task that was interrupted), then
- * *pxHigherPriorityTaskWoken will get set to pdTRUE internally within the
- * xTimerChangePeriodFromISR() function.  If xTimerChangePeriodFromISR() sets
- * this value to pdTRUE then a context switch should be performed before the
- * interrupt exits.
- *
- * @return pdFAIL will be returned if the command to change the timers period
- * could not be sent to the timer command queue.  pdPASS will be returned if the
- * command was successfully sent to the timer command queue.  When the command
- * is actually processed will depend on the priority of the timer service/daemon
- * task relative to other tasks in the system.  The timer service/daemon task
- * priority is set by the configTIMER_TASK_PRIORITY configuration constant.

- * BaseType_t xTimerPendFunctionCallFromISR( PendedFunction_t xFunctionToPend,
- *                                          void *pvParameter1,
- *                                          uint32_t ulParameter2,
- *                                          BaseType_t *pxHigherPriorityTaskWoken );
- *
- *
- * Used from application interrupt service routines to defer the execution of a
- * function to the RTOS daemon task (the timer service task, hence this function
- * is implemented in timers.c and is prefixed with 'Timer').
- *
- * Ideally an interrupt service routine (ISR) is kept as short as possible, but
- * sometimes an ISR either has a lot of processing to do, or needs to perform
- * processing that is not deterministic.  In these cases
- * xTimerPendFunctionCallFromISR() can be used to defer processing of a function
- * to the RTOS daemon task.
- *
- * A mechanism is provided that allows the interrupt to return directly to the
- * task that will subsequently execute the pended callback function.  This
- * allows the callback function to execute contiguously in time with the
- * interrupt - just as if the callback had executed in the interrupt itself.
- *
- * @param xFunctionToPend The function to execute from the timer service/
- * daemon task.  The function must conform to the PendedFunction_t
- * prototype.
- *
- * @param pvParameter1 The value of the callback function's first parameter.
- * The parameter has a void * type to allow it to be used to pass any type.
- * For example, unsigned longs can be cast to a void *, or the void * can be
- * used to point to a structure.
- *
- * @param ulParameter2 The value of the callback function's second parameter.
- *
- * @param pxHigherPriorityTaskWoken As mentioned above, calling this function
- * will result in a message being sent to the timer daemon task.  If the
- * priority of the timer daemon task (which is set using
- * configTIMER_TASK_PRIORITY in FreeRTOSConfig.h) is higher than the priority of
- * the currently running task (the task the interrupt interrupted) then
- * *pxHigherPriorityTaskWoken will be set to pdTRUE within
- * xTimerPendFunctionCallFromISR(), indicating that a context switch should be
- * requested before the interrupt exits.  For that reason
- * *pxHigherPriorityTaskWoken must be initialised to pdFALSE.  See the
- * example code below.
- *
- * @return pdPASS is returned if the message was successfully sent to the
- * timer daemon task, otherwise pdFALSE is returned.
- *
- * Example usage:
- * @verbatim
- *
- *	// The callback function that will execute in the context of the daemon task.
- *  // Note callback functions must all use this same prototype.
- *  void vProcessInterface( void *pvParameter1, uint32_t ulParameter2 )
- *	{
- *		BaseType_t xInterfaceToService;
- *
- *		// The interface that requires servicing is passed in the second
- *      // parameter.  The first parameter is not used in this case.
- *		xInterfaceToService = ( BaseType_t ) ulParameter2;
- *
- *		// ...Perform the processing here...
- *	}
- *
- *	// An ISR that receives data packets from multiple interfaces
- *  void vAnISR( void )
- *	{
- *		BaseType_t xInterfaceToService, xHigherPriorityTaskWoken;
- *
- *		// Query the hardware to determine which interface needs processing.
- *		xInterfaceToService = prvCheckInterfaces();
- *
- *      // The actual processing is to be deferred to a task.  Request the
- *      // vProcessInterface() callback function is executed, passing in the
- *		// number of the interface that needs processing.  The interface to
- *		// service is passed in the second parameter.  The first parameter is
- *		// not used in this case.
- *		xHigherPriorityTaskWoken = pdFALSE;
- *		xTimerPendFunctionCallFromISR( vProcessInterface, NULL, ( uint32_t ) xInterfaceToService, &xHigherPriorityTaskWoken );
- *
- *		// If xHigherPriorityTaskWoken is now set to pdTRUE then a context
- *		// switch should be requested.  The macro used is port specific and will
- *		// be either portYIELD_FROM_ISR() or portEND_SWITCHING_ISR() - refer to
- *		// the documentation page for the port being used.

-/**
- * @brief Logging library
- *
- * Log library has two ways of managing log verbosity: compile time, set via
- * menuconfig
- *
- * At compile time, filtering is done using CONFIG_LOG_DEFAULT_LEVEL macro, set via
- * menuconfig. All logging statments for levels higher than CONFIG_LOG_DEFAULT_LEVEL
- * will be removed by the preprocessor.
- *
- *
- * How to use this library:
- *
- * In each C file which uses logging functionality, define TAG variable like this:
- *
- *      static const char *TAG = "MODULE_NAME";
- *
- * then use one of logging macros to produce output, e.g:
- *
- *      LOGW(TAG, "Interrupt error %d", error);
- *
- * Several macros are available for different verbosity levels:
- *
- *      LOGE - error
- *      LOGW - warning
- *      LOGI - info
- *      LOGD - debug
- *      LOGV - verbose
- *
- * To override default verbosity level at file or component scope, define LOG_LEVEL macro.
- * At file scope, define it before including esp_log.h, e.g.:
- *
- *      #define LOG_LEVEL LOG_VERBOSE
- *      #include "dxx_log.h"
- *
- * At component scope, define it in component makefile:
- *
- *      CFLAGS += -D LOG_LEVEL=LOG_DEBUG
- *
- *
