lilygo-epd47-RandomImageBox

E-paper and arduino tinkering project using https://github.com/Xinyuan-LilyGO/LilyGo-EPD47

The project

The goal of this project was to create a box and display a random image on the e-paper by opening the box

_{NOTE: Original idea was to fetch new picture data from web but without a sd card I wasn't able to do this. Also the chip alone can only store about 4 pictures}

Components

The main and basically only needed component is LILYGO® T5-4.7 inch E-Paper as it includes the ESP32 MCU

Converting images to be displayable by the E-Paper

Use photo editor like Paint to make sure the photo is about correct size (960x540) and save it as a .png

Make sure you have python installed

Go to the scripts folder

Install pillow using

python -m pip install pillow

Convert image to .h file using

python imgconvert.py -i image.png -n pic -o pic.h

Add .h files to drawImages folder

ISSUE:

The chip can store only about 4 pictures in .h files. MicroSD card module should be added to be able to store more pictures

Building process

Steps will be added in the future
