UiFLow2 M5Dial and IOEXT2

[HorstdieWurst]

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.

Hello @HorstdieWurst

in UIFlow2 alpha-29 M5Dial and EXT.IO2 works for me. I quickly tested input and output.

Can you be more specific as to what exactly doesn't work for you? Maybe share the UIFlow blocks you've tired?

As for UIFlow1 - the latest version is UIFlow 1.13.0 (which offers EXT.IO2).

Thanks

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.

Hello @HorstdieWurst

ok, I see. It looks like the count do loop fires of the i2c commands too quickly. I can make it work by adding a sleep 1 milliseconds block after the set servo pulse block.

Thanks

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?

Hello @HorstdieWurst

make sure the EXT.IO2 unit is connected to the red Groove port of M5Dial. I get the error you mentioned if I disconnect the unit.

Below are the blocks that work for me.

Note: there is a typo in M5Dial firmware - it expects write_servo_pluse() instead of write_servo_pulse(). Therefore you cannot use the prepared block (until UIFlow firmware is fixed). Instead an Execute mpy code block can help out. PR to fix typo created.

Thanks

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.

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?
