Pico ePaper Display
Raspberry Pi Pico drawing random images and quotes from an SDCard onto a 7-color epaper display.
Demo
Russian CRT TV converted into an eco-friendly epaper photo frame.
Operation
The Pico randomly picks a BMP file along with a random quote (joke) from the SD card and draws it on the epaper display. Then it enters sleep mode, waits for several minutes and repeats the whole process.
It is ok to remove the SD card while the system is powered on. The card is always mounted anew and there is a fallback when some data is not available.
Build
Parts
- Raspberry Pi Pico
- 5.65 ACeP 7-Color Waveshare ePaper display
- SDCard SPI module
Construction
- connect the SDCard module via SPI0 (pins 11, 12, 13, 14, 15)
- connect the epaper display via SPI1 (pins 16, 17, 18, 19) and pins 8 (DC), 9 (CS), 12 (Reset) and 13 (Busy)
Compile
- download some
jpgimages into thegallery/folder - run the Makefile via
maketo convert the images into 7-colorbmpfiles and download ajokes.jsonfile - upload the contents of
build/onto an SD card - flash MicroPython onto the Raspberry Pi Pico
- upload the
*.pyfiles onto the Pico via Thonny - insert the SDCard into the module
- power it up!
