Hello.
My matrix fail's after some time. And wenn I restart the program it works fine for some time.
and after some time it is failing again.
how can this happen ?
Here is the code.

I would put a few print(...) lines in the code, specifically before and after:
line = multimon_ng.stdout.readline()
multimon_ng.poll()as it could be the readline that is blocking

Hello rm-hull,
Thank you for you're valued answer.
The multimode code is correct. Like you can see I can comment the Multimon lines and just write a string in "line" wenn I do this the fail still occur
I notice wenn the code is running ( line contain the values for the If state ment ) and I lower the value for
with canvas(virtual) as draw:
device.contrast(15 * 16)#tot 15the problem is starting right a way.

Hello.
I supply my print with a external 5v 5amp laptop supply. then I heave this problem. Wenn I use the raspberry USB to feed the power I down't have this problem.
So the problem is there wenn I feed a external 5v. Is there a way to feed external.
Ore do you heave a clue to fix this.
thijstriemstra commented
Wenn I use the raspberry USB to feed the power I down't have this problem.
If it works, why not use it?
paulvanderheijden90 commented
@thijstriemstra
ofcourse this is the easy way. But I need some more devices to power.
so I need more amps
thijstriemstra commented
Good to hear you got it to work.
