+# Pico ePaper Display
+
+Raspberry Pi Pico drawing random images and quotes from an SDCard onto a 7-color epaper display.
+
+
+## Demo
+
+![finished display](demo.jpg)
+
+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!
