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.

1. The library already contains all the hardware drivers for T-Watch
2. Using TFT_eSPI as the display driver, you can directly call TFT_eSPI through the construction object.
3. 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.
4. For the use of lvgl please refer to lvgl docs

• Clone this git repository into your sketchbook/libraries folder. For more info, see https://www.arduino.cc/en/Guide/Libraries

• In the Arduino board select TTGO T-Watch
• In the Arduino File -> Examples -> TTGO T-Watch

• 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
  • Using Arduino IDE with the development repository
    • Instructions for Windows
    • Instructions for Mac
    • Instructions for Debian/Ubuntu Linux
    • Instructions for Fedora
    • Instructions for openSUSE

• Since Twatch uses a special IO as the SD interface, please remove the SD card when downloading the program.

• 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.
