Revision as of 03:12, 9 April 2020

Description

A low-energy, high-falutin, electronic paper (ePaper / eInk / EPD) display for your Pi, in two different colour schemes: black/white.
This 250x122 pixel eInk display is perfect for displaying simple graphics and clearly rendered text. It has low power consumption, a wide viewing angle, and is readable in bright sunlight. After power is off, the last display can be kept.
Everything is completely assembled, no soldering is required, you can plug the eInk display directly into the GPIO pin of the Raspberry Pi. It‘s also has an 8-pin PH2.0 socket that can be connected to other development boards.
It'll work with any 40-pin version of the Pi, including Pi Zero and Pi Zero W.

Operations Guide

Start the RPi and type in the following commands into the terminal.

1. sudo raspi-config

Then restart the RPi.

1. sudo reboot

Make sure that SPI has not been occupied by other devices and you can check this issue in /boot/config.txt.
Library Installation
Install BCM2835, and enter the RPi terminal and then run the next command.

1. wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.60.tar.gz
2. tar zxvf bcm2835-1.60.tar.gz
3. cd bcm2835-1.60/
4. sudo ./configure
5. sudo make
6. sudo make check
7. sudo make install

3. sudo dpkg -i wiringpi-latest.deb
4. gpio -v

Install Python function library.

1. #python2
2. sudo apt-get update
3. sudo apt-get install python-pip
4. sudo apt-get install python-pil
5. sudo apt-get install python-numpy
6. sudo pip install RPi.GPIO
7. sudo pip install spidev
8. #python3
9. sudo apt-get update
