All the demo files of this product are stored in file DFRobot_GDL->example->basic.

Please open the corresponding constructed functions (DFRobot_ST7789_240x240_HW_SPI) before burning demo into your device.

The product is a Breakout module. It adopts SPI communication and has onboard GDI interface, which reduces the complexity of wiring and can easily display the contents read from SD card.

GDI interface could only work well with maincontrollers with GDI.

It is recommended to use Arduino 1.8.10 and above.

If the SD card is not in good contact, it may fail to initialize, and then please try to replug it.
