SPI Serial Module
TEST-ARD-DIY-02
Published
SPI color display module demo page using minimal signal lines, suitable for resource-constrained embedded systems.(Standalone product 2)
Introduction
- SPI interface saves MCU pins.
- Supports partial refresh and common graphics drawing workflows.
- Interface, parameters, and FAQ are all maintainable via backend.
- Standalone product ID: 2.
Specifications
Specifications to be added.
Hardware
Core signals include SCK, MOSI, CS, DC, and RESET; backlight is independently controlled. Do not apply 5V directly to 3.3V signal pins.
Size
- 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.
FAQ
- 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.
