This library is based on the original Waveshare library for Raspberry Pi, available here.
At the moment it supports 1.54" Waveshare two-color E-Paper Display only.
- Drawing lines (horizontal, vertical and between two arbitrary points)
- Drawing rectangles and circles, both regular and filled
- Drawing images from raw data (
list
orbytes
object) - Drawing images from BMP files (Windows-style 1-color bitmap)
- Adjusting screen orientation
- Power saving mode (~30uA)
The e-paper display uses 6 data lines for communication:
reset = Pin('P19')
dc = Pin('P20')
busy = Pin('P18')
cs = Pin('P4')
clk = Pin('P21')
mosi = Pin('P22')
epd = epd1in54b.EPD(reset, dc, busy, cs, clk, mosi)
Consult main.py
for an example usage.
In order to use fonts, copy them to epd/lib
directory, or (recommended) freeze them in firmware. See this blog post for more info on how to do it.
