Got it displaying text on the screen but where's the rest of the functionality?

Looks like the micropython port was just a proof-of-concept. I can clear the screen, display a JPG and draw some text, but that's it. No "draw a dot/line/circle/arc" functions, no "change the font" function (I found the change the font size, but nothing to change the ttf font or bold/italic/...). Nothing too fancy, but it works. Only the basics have been implemented it seems. Also, I'm seeing some ghosting but it's intermittent. Sometimes the screen has ghosting, sometimes it doesn't. See screenshot of the ghosting below.

Is there framebuffer support? Drawing text to the screen seems to take a while. Would be nice to write to the framebuffer and have the whole screen update at once.

Also, touchscreen example maybe? I found this: https://github.com/Xinyuan-LilyGO/lilygo-micropython/blob/master/extmod/display/epd/test/l58.py but I haven't tried to create an example with it yet.

1. Regarding "draw a dot/line/circle/arc" functions, use framebuffer or bytearray to draw, and then call EPD47.bitmap() to display. It is completely possible to use python.

2. We have also discovered the problem of ghosting, and we have not found the reason for it.

3. touchscreen can refer to https://github.com/Xinyuan-LilyGO/lilygo-micropython/blob/master/extmod/touch/l58.py

Got the touchscreen working!

from l58 import L58
from time import sleep
from machine import I2C,Pin

tp = L58(I2C(1, scl=Pin(14), sda=Pin(15), freq=400000), 0x5A)
tp.begin()
while True:
    for i in range(0, tp.scanPoint()):
        data = tp.getPoint()
        print(data)
    sleep(0.1)
