Скачать или смотреть Ep. 2: T-Deck Schematic, TFT Touch Display, Battery Voltage ADC

In Episode 2 we evaluate the LILYGO T-Deck Schematic and its components. Then we use the TFT_eSPI library to drive the LED display, then we create code to access the Touch function of the display. Also we check out how to use the ESP32 ADC to check the battery voltage.
