esp32-GC9A01-round

An example project showing two different clocks on two round TFT SPI displays, using ESP32 and the eTFT_SPI lib. I built this to help learn how to make clocks with better and simpler code quality.

Some things demonstrated:

• Using the platformio.ini file to configure eTFT_SPI settings
• Switching between two different displays by toggling the CS pins of each
• Using native time(), localtime_r(), configTime(), setEnv() and timezone strings, to update via NTP without external libraries
• Connect to WiFi pattern with time sync, initialization, error handling and debug callbacks for WiFi events.
• Drawing both analog and digital clock faces using eTFT_SPI and TFT_eSprite primatives, as well as font handling.
• Storing fonts on an SPIFFs partition, updated by PlatformIO
• Track frame rate and timing in the loop

This project uses WiFiManager - which means a WIFI access point will be created for you to configure WiFI settings when you first flash a new board. After that, the settings will stay.
