mmh, so the Pin for the serial port TxD only gets used when parallel=3 (and RxD only ever with rare 1:64 LED panels). Also from my experience it sh…

This is strange. Is there anything else running on the Pi that could conceivable mess with the PWM subsystem ? Some other LED library or something ? …

Cool. Very nice. Make sure when you have this as a product to provide your and the libraries' source-code to the receiver of this product (includin…

Yes, if this is a HC245, then you very likely need to make yourself a logic level shifter board (Make one yourself with the provided board or get a…

Wonderful to hear that you got it to work. I think I need to update the documentation if this is now a thing that the Pi comes with the audio stuff…

See also issue #150 - that sounds very similar and was fixed by removing the sound subsystem.

Does your Raspberry Pi have audio subsystems enabled by default ? This needs to be off because it uses a similar hardware subsytem.

@hzeller

Ok. so that might need to be switched off. If that can be confirmed (for my last Pi, it just worked without), I'd love a suggestion what to add to …

Can you leave out these unrelated changed from the pull request ?

Ah, if it has a HC245, you need a level shifter to convert the 3.3V logic level to 5V and can't directly connect it to the Pi GPIOs. Have a look at…

Mmh, it worked for me straight away on the Pi3, so not sure what the trouble is you are running into.

Can you show the back of the board and the connector ?

There is no known reason. You have to figure out what systemd is doing that is messing with the program. Does it call something after this program …
