Context
This tool is showcased in the project IotaWorkshop
Summary
This is a high level e-paper libaray. It supports QR code displays and allows easy lines of text writing along with right text align. Ideally if used this libaray should be imported to use the helpful class EPD.
Note This works for all waveshare screens when you import it. Simply change the line from,
from waveshare_epd import epd1in54_V2
To whatever screen you have. For instance the 5.83 inch BW screen
from waveshare_epd import epd5in83
Or the color version (bc)
from waveshare_epd import epd5in8bc
Installation
This project depends on Pillow but there are a variety of ways of installing it so I did not mark it as a dependency in the pypi package, you can install it using,
pip install pillow
Simply install this package from the pypi repo
pip install piepd
Command Line Interface
There are a few example displays that can be run through the cli,
epd occipied #Displays text saying the tools is occupied
epd --help #To see altenative displays
Implementation Example
from epd import EPD
epd = EPD()
epd.setFontSize(21)
epd.drawText("Hello world",draw=False) #Draws this text on the screen
epd.drawText("Left",draw=False) #Does not display yet until draw=True
#The following line will right align the text and put it on the previous line
epd.drawText("Right",right=True,overlap=True,draw=True)
#Once you are completly done using the dislplay run
epd.close()
