# 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. |

|
|
|
### Parts |
|
|
|
- Raspberry Pi Pico |
|
|
|
- [5.65 ACeP 7-Color Waveshare ePaper display](https://www.waveshare.com/5.65inch-e-Paper-Module-F.htm) |
|
|
|
- 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 |
|
|
|
1. download some `jpg` images into the `gallery/` folder |
|
|
|
2. run the Makefile via `make` to convert the images into 7-color `bmp` files and download a `jokes.json` file |
|
|
|
3. upload the contents of `build/` onto an SD card |
|
|
|
4. flash MicroPython onto the Raspberry Pi Pico |
|
|
|
5. upload the `*.py` files onto the Pico via Thonny |
|
|
|
6. insert the SDCard into the module |
|
|
|
7. power it up! |
