- # 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](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!
