adafruit 2.13 monochrome eink does not work

Post by _U3U_ »

I recently purchased an adafruit adafruit 2.13 monochrome eink bonnet(https://learn.adafruit.com/2-13-in-e-ink-bonnet/usage) that comes with pin hat fitted for raspberry pi. Upon initial setup the screen worked (drew rectangles etc), but it has since stopped working even after I tried restarting the rapspberry pi/disconnecting and reconnecting the bonnet.

When I run the code it often hangs at:

Code: Select all

busy_wait time.sleep(0.01)
if I disable the busy pin, it instead does

Code: Select all

time.sleep(3)
and still nothing gets rendered on the screen

the code in question is line 81 of file:
https://github.com/adafruit/Adafruit_Ci ... epd/epd.py

I am not sure if this is a hardware problem with the bonnet or something is wrong with my RPi 3B, any advice is appreciated.

Are you able to run some of the code found in the example folder?

Maybe start with the epd_pillow_demo.py which is on the learn/guide page you had been following.
