This project provides python libraries for talking to the Waveshare E-Ink Display from a Raspberry PI3.
For more information about this display, see the waveshare site. There is also a product wiki page.
It requires the GPIO library that is typically available on the Raspberry PI.
This diagram is for the Pi3, other Pi may work, but the pinout could be different. Be sure to check before trying it if you're not using a Pi3.
| PI3 Pin | E-Ink Pin |
|---|---|
| 3.3 v 1 | 6 3.3v |
| GND 6 | 5 GND |
| GPIO15 10 | 4 DOUT |
| GPIO14 8 | 3 DIN |
| GPIO04 7 | 2 WAKE_UP |
| GPIO02 3 | 1 RESET |
The libpython-dev and RPIO libraries are needed.
sudo apt-get install libpython-dev
pip install --user RPIO
There are a set of unit tests (which are executed by the Makefile) which basically just make sure the code produces what was listed in the wiki as being valid commands.
Assuming everything is wired up according to the above diagram, you may still need to disable the bluetooth serial connection (or use a different file path) and enable the uart.
To disable the bluetooth serial connection, edit /boot/cmdline.txt and delete
console=serial0,115200. Then edit /boot/config.txt and add
dtoverlay=pi3-disable-bt and eanble_urar=1 and reboot.
There are some examples, see examples.py and ip.py.
