First program for the Waveshare 2.7" ePaper HAT

hello_epaper1.py

import sys
sys.path.insert(1, "./lib")

import epd2in7b
from PIL import Image, ImageDraw, ImageFont

epd = epd2in7b.EPD() # get the display
epd.init()           # initialize the display
print("Clear...")    # prints to console, not the display, for debugging
epd.Clear(0xFF)      # clear the display

def printToDisplay(string):
    HBlackImage = Image.new('1', (epd2in7b.EPD_HEIGHT, epd2in7b.EPD_WIDTH), 255)
    HRedImage = Image.new('1', (epd2in7b.EPD_HEIGHT, epd2in7b.EPD_WIDTH), 255)
    
    draw = ImageDraw.Draw(HBlackImage) # Create draw object and pass in the image layer we want to work with (HBlackImage)
    font = ImageFont.truetype('/usr/share/fonts/truetype/google/Bangers-Regular.ttf', 30) # Create our font, passing in the font file and font size
    
    draw.text((25, 65), string, font = font, fill = 0)
    
    epd.display(epd.getbuffer(HBlackImage), epd.getbuffer(HRedImage))
    
printToDisplay("Hello, World!")    

There are 2 problems I ran into while trying to do this.
The first was that the epd2in7b.py file has this line:

from . import epdconfig

which returned an error. I just removed the

from . 

part, so now I'm left with

import edpconfig

which does work since it's in the same directory.
Second, the

edp.Clear()

function doesn't take any arguments.
So the code I'm now left with is this:

import sys
sys.path.insert(1, "./lib")

import epd2in7b
from PIL import Image, ImageDraw, ImageFont

epd = epd2in7b.EPD() # get the display
epd.init()           # initialize the display
print("Clear...")    # prints to console, not the display, for debugging
epd.Clear()      # clear the display

def printToDisplay(string):
    HBlackImage = Image.new('1', (epd2in7b.EPD_HEIGHT, epd2in7b.EPD_WIDTH), 255)
    HRedImage = Image.new('1', (epd2in7b.EPD_HEIGHT, epd2in7b.EPD_WIDTH), 255)
    
    draw = ImageDraw.Draw(HBlackImage) # Create draw object and pass in the image layer we want to work with (HBlackImage)
    font = ImageFont.truetype('/usr/share/fonts/truetype/google/Bangers-Regular.ttf', 30) # Create our font, passing in the font file and font size
    
    draw.text((25, 65), string, font = font, fill = 0)
    
    epd.display(epd.getbuffer(HBlackImage), epd.getbuffer(HRedImage))
    
printToDisplay("Hello, World!")

Oh, good to know. The company must have changed the clear() method to no longer take a color code.

You should include a try except to be able to handle errors or cut execution ;)
