The code bin will demonstrate the basic functionality of T-Watch, including all on-board chips from T-Watch, using the latest lvgl6.0 as the display graphics framework.
|
|
|
|
|
|
# Characteristics:
|
|
1. The library already contains all the hardware drivers for `T-Watch`
|
|
1. Using TFT_eSPI as the display driver, you can directly call TFT_eSPI through the construction object.
|
|
1. Using lvgl 6.0 as the display graphics framework, the driver method has been implemented, you only need to call lvgl api according to your own needs.
|
|
1. For the use of lvgl please refer to **[lvgl docs](https://docs.littlevgl.com/en/html/index.html)**

# Installing
|
|
- Download a zipfile from github using the "Download ZIP" button and install it using the IDE ("Sketch" -> "Include Library" -> "Add .ZIP Library..."
|
|
- Clone this git repository into your sketchbook/libraries folder.
|
|
For more info, see https://www.arduino.cc/en/Guide/Libraries
|
|
|
|
# How to find the sample program
|
|
- In the Arduino board select `TTGO T-Watch`
|
|
- In the Arduino File -> Examples -> TTGO T-Watch
|
|
|
|
# Note
|
|
- If you don't have the `TTGO T-Watch` option in your board manager, please update the esp32 board as follows:
|
|
- Using Arduino IDE Boards Manager (preferred)
|
|
+ [Instructions for Boards Manager](docs/arduino-ide/boards_manager.md)
|
|
- Using Arduino IDE with the development repository
|
|
+ [Instructions for Windows](docs/arduino-ide/windows.md)
|
|
+ [Instructions for Mac](docs/arduino-ide/mac.md)
|
|
+ [Instructions for Debian/Ubuntu Linux](docs/arduino-ide/debian_ubuntu.md)
|
|
+ [Instructions for Fedora](docs/arduino-ide/fedora.md)
|
|
+ [Instructions for openSUSE](docs/arduino-ide/opensuse.md)

# Precautions:
|
|
- Since Twatch uses a special IO as the SD interface, please remove the SD card when downloading the program.
|
|
|
|
|
|
# About power consumption:
|
|
- Currently off the screen, turn off WiFi, Bluetooth and other peripherals consume about 4mA (non-deep sleep), turn on the screen power, do not turn on WiFi, Bluetooth and other peripherals around 65mA, please refer to `example -> SimpleWatch` for the specific code.
