* Add int HAL_PIN_Find(const char *name) for all platforms add simple selftest (and added some alias strings to windows pins) * fix ESP * fix second occurence of isdigit for ESP by casting to unsigned char * Moved code for HAL_PIN_Find to "src/hal/generic/hal_pins_generic.c" and removed it from the (few) platforms aleady implemented it. Added some "complex" pin alias descriptions for windows to test made function case insensitive - introducing "char *wal_stristr(const char *haystack, const char *needle);" as a case insensitiver version of "strstr" in new_common.c * Try fix windows (by including src\hal\generic\hal_pins_generic.c) Enable ENABLE_TEST_COMMANDS for all platforms to do some testing * comment out weak functions for Windows * including "../hal/hal_pins.h" in cmd_test.c to clear warning about HAL_PIN_Find() * comment out StackOverflow test for ESP - it won't compile * fix * Moved code from hal_pins_generic.c to new_pins.c reverted usage of hal_pins_generic.c in Windows build changed Tokenizer_GetPin() * Changed driver commands to use Tokenizer_GetPin() instead of Tokenizer_GetArgIntegerDefault() to get drivers pins * Fix typo in drv_pinMutex.c * Fix cmd_test.c and ds1820_full.c Added debug output to Tokenizer_GetPin() * Removed tesing and debugging code * Also allow pin alias in SetPinRole command * Fix typo
Introduction
OpenBK7231T/OpenBeken is a Tasmota/ESPHome alternative for modern Tuya-based modules, offering MQTT and Home Assistant compatibility.
Although this repository is named OpenBK7231T_App, it has evolved into a multi-platform application, supporting builds for multiple chipsets from various vendors, including ESWIN, Transa Semi, Lightning Semi, Espressif, Beken, WinnerMicro, Xradiotech/Allwinner, Realtek, and Bouffalo Lab.

- BK7231N (eg CB2S, CB2L, WB2L_M1)
- BK7231M, this is a non-Tuya version of BK7231N with
00000000keys, sometimes labelled as Belon BL2028. example1 example2 - T34 (flash as if standard BK7231N), see flashing trick

Please use automatically compiled binaries from the Releases tab. To build OpenBeken yourself for any supported platform, fork our version of the submodule SDK first, and then check out this app repository alongside it. Details further down. Alternatively consider using the easier override method.
See our guides in Russian: BK7231N/T34, and BL602 RGB, and Youtube guide for BK7231/T34
