I got a new extio2 today and it works straight away. Many thanks for your help.
Can anyone tell me whether I can generate a 10, 12 or 16 bit PWM signal?

Ok this is what I tried and I got the error message. So I guess the my extio2 is broken. I will try to get a new a and try it again. Thank you uo to here ;)
Is it possible to send a normal 8 bit, 12 bit or best would be a 16 bit PWM to the i/os? Maybe with a mpy code? There is just the RGB mode which I do not understand, how they send 3x8bit on one i/o.

No the problem appears already when I set pin0 to servo or any thing else. Am I missing smething about the i2c setup?
Maybe you could show me a basic setup for a pin to send a pulse to pin 0 or something like this. Maybe my ioext2 is broken?

Te first one is ok and gives no error. The second picture gives an error 19 enddev. I have got no clue what to do.

I am not able to get the IOEXT2 work with the M5Dial. Is this still not possible because of the Alpha 0-29?
Anyone any idea? I also trried to make it work with Core2 and UIFlow1.9.5 but ioext2 is not listed here.

Hey there. I'm trying to run pin 25 and 26 with PWM in 16 Bit on the M5Stack Core2 using UIFlow. I did the same on the M5Stack Core using Arduino and it work. Has anyone got an idea where the problem is?

I think the result is only 12 Bit.
