硬件说明
Core signals include SCK, MOSI, CS, DC, and RESET; backlight is independently controlled. Do not apply 5V directly to 3.3V signal pins.
使用说明
- Connect power and SPI signals per the pinout table.
- Configure chip select and orientation in the driver.
- Run a solid color test first, then load the graphical UI.
- Adjust SPI clock based on bus length.
常见问题
- Why is the screen all white?
- Check reset, chip select, data/command pins, and initialization model.
- What if the image has noise?
- Lower the SPI clock and shorten the connection wires.
