    FAQ

    • There are two drives u8g2 and DFRobot_GDL are provided, should I install both of them?
      You just need to select one to install. Please note that u8g2 is a powerful lcd library for black and white liquid crystals, and thre are functions like built-in capacitive resistance touch, simple UI and u8g2 partial functions in DFRobot_SDL, it supports both black and white, and colorful LCD.
