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_eSpriteprimatives, 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.
