/dev/spidev0,0 on the Rock64 - Does anyone know how to enable it?
#11
Please check connection again. I see GND connected to pin 18 and not pin 20 and other errors.
Do you have 4.2" or 4.2"b/c ?



I modified 4.2" (monochrome) python demo code. Do not press ctrl-c main.py should be done after 35 seconds.

I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" Angry. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !

It freaking works!!! That is awesome. You are awesome :-)

Normally I don't do work on weekends, but this is so great :-))

I might/will have a couple of context-questions to grasp a few things and with your permission/help I'll write a doc how to use the eInk Displays in general in the following weeks.

Thanks again :-)

Did you get to writing up a doc on eInk Displays and the Rock64 ??

Would be great

Thanks to @mcerveny's posts in this thread, I was able to get a waveshare 2.7" e-paper hat working on my Rock64 v2, Armbian.

However, as mentioned above, due to the Rock64 pin out, it does not seem readily possible to utilize the display as a 'hat', as intended... which is a shame.
