Home Life Display
Make a Raspberry Pi E-paper display show info in the morning/evening which I care about:
-
Org agenda
-
Weather conditions for biking to work on the current day
-
Kanji study schedule
The E-paper panel is a Waveshare E-Ink three-color 7.5 inch panel with HAT.
Setup
More for my own reference than anyone else, which is why there are some obvious general setup steps specific to Pi, not this project.
Operating System
This section documents a general, minimal, and useful Pi setup.
-
Install Raspbian Lite via NOOBs onto Raspberry Pi 3 B+.
-
Run
passwd
to change default password -
sudo apt update && sudo apt upgrade
Raspi-config
sudo raspi-config
-
Enable SSH in Interfacing Options
-
Set localisation options (for me, it means checking
en-US
and setting timezone to Los Angeles) -
Set Wifi hostname and password, if necessary
Clone Repository
sudo apt install git
git clone --recurse-submodules https://github.com/makuto/home-life-display
If run with --recurse-submodules
as shown, it will automatically get the Waveshare e-Paper code repository.
If you forgot:
cd home-life-display
git submodule init
git submodule update
Third Party Setup
Org Parsing
I use Org-mode for my Agenda:
sudo pip3 install orgparse
Fonts
For Japanese:
sudo apt-get install fonts-takao
E-paper Setup
Python dependencies
sudo apt install python3-pip libjpeg-dev
sudo pip3 install spidev RPi.GPIO pillow
Install Python API
There was no setup.py
nor init.py
for the e-Paper API, so just symlink them to the same directory instead:
cd home-life-display
ln -s e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd/epd7in5bc.py epd7in5.py
ln -s e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd/epdconfig.py epdconfig.py
If you get failure to import, open the epd7in5.py
and fix it like so:
import epdconfig
Enable SPI interface
nano /boot/config.txt
Uncomment the line with dtparam=spi=on
.

Waveshare Example Code
Left here for reference.
Download E-paper Demo code (direct link) (Github).
For decompressing the Waveshare example code:
sudo apt install p7zip
Install Fonts
For the unmodified demo code, you need to install the Chinese + English font they chose:
sudo apt install ttf-wqy-microhei
