This is an unofficial repository for the Waveshare ESP32-C6 development board with a 1.9-inch TFT display and a resolution of 170 x 320 pixels. It contains example programs for all the board's components for the Arduino IDE. The board is available in two versions: without a touch interface (but with an RGB LED) or with a touch interface and an external antenna connector. My examples refer entirely to the board with the touch surface.
You can find the manufacturer's official repository via this link: https://github.com/waveshareteam/ESP32-C6-LCD-1.9
This repository accompanies the article "A detailed look at the Waveshare ESP32-C6 1.9-inch ST7789 TFT display with touch interface Development Board" published here: https://medium.com/@androidcrypto/a-detailed-look-at-the-waveshare-esp32-c6-1-9-inch-st7789-tft-display-with-touch-interface-ced633da6291.
In the Documentation" folder, you will find files and descriptions taken from the original repository or the manufacturer's shop page and provided here as copies. Naturally, all rights remain with the manufacturer.
