Waveshare EPaper 1.54 Raspberry Pi

I bought an Waveshare E-Paper 1.54 for a different project so.. here a guide on how to install it

Step 1: Item List

Here is what you'll need:

  • a Raspberry pi 3
  • remote machine to SSH to the pi or a screen and keyboard to connect to it directly
  • WaveShare E-paper module 1.54 (model A)

Step 2: Connecting to the PI

Follow the cable name and the drawing when connecting the screen to the Raspberry pi IO

Step 3: Download and Install Library

I have added the library download files to the project, original links are below

https://www.waveshare.com/wiki/File:Bcm2835-1.39.t...

https://www.waveshare.com/wiki/File:WiringPi.tar.g...

Installation

Enter WiringPi folder, then follow these commands to install:

chmod 777 build
./build

check the installation with :

gpio –v

Go to the bcm2835 libraries folder, then follow these commands to install:

<p>./configure<br>make sudo 
make check 
sudo make install</p>

Download the demo code

remake the files in bcm2835 and wiringpi folder by going to the folder and do

cd PATH/OF/DEMO/FOLDER/Rasberry/bcm2835<br>make clean
make

<p>cd PATH/OF/DEMO/FOLDER/Rasberry/wiringpi</p><p>make clean
make</p>

Step 4: Update Your Own Image

Before you can run the code you need to make minor changes .

The code uses a font the is not nativly on the Rasbien instell so change the font type

font = ImageFont.truetype('/usr/share/fonts/truetype/wqy/wqy-microhei.ttc', 24)

to any other font that exist on your system.

check available font by doing and change the result , i have changed it to

ls /usr/share/fonts/truetype/
font = ImageFont.truetype('/usr/share/fonts/truetype/freefont/FreeSansBold.ttf', 24)<br>

in main.py

<p>image = Image.open('free-rick-design-700x700.bmp')</p><p>epd.display(epd.getbuffer(image))
time.sleep(2)</p>

Step 5: Change the Demo Code

From the Example file in the demo here are some command you can use inside your own python scripts

import the install interface

import epd1in54<br>from PIL import Image,ImageDraw,ImageFont

Init the Screen

epd = epd1in54.EPD()
epd.init(epd.lut_full_update) 
epd.Clear(0xFF)

Open and Display an image

image = Image.open('1in54.bmp')<br>epd.display(epd.getbuffer(image))
