Thanks MostlyHarmless for your explanation to ease the build of micropython firmware.

Yes, I think it definetly worth a specific topic.

I have made some experiments with Timer with a step / dir driver (like TM2130) https://github.com/pidou46/ustepper/blob/master/ustepper.py The general idea is to setup a PWM output and stop it with a Timer. You just need to compute the Timer delay to achieve the desired stroke. This solution is quit...

This latest release bring studding stability, it works flawlessly for all my uses cases.

kudos to Aivar

Still, I think OutoftheBOTS_ is right it could be usefull to have synchro pin value setting build in micropython, it would bring easyness and portability, I will probably open an issue on git repository since I'm (still) not able to make a PR by myself...

Nice, it works like a charm with the latest build.

Thank you

I have tried the viper code, but I get the following error:
I run the same code on esp8862 and doesn't get the error

Thanks, I have build a complete working sample: from machine import Pin, mem16 p12=Pin(12, Pin.OUT) p14=Pin(14, Pin.OUT) p12.value(0) print(p12.value()) p14.value(0) print(p14.value()) #esp32 GPIO_OUT_REG=0x3FF44004 #set GPIO12 and GPIO14 to 1 GPIO=0b00000000000000000101000000000000 mem16[GPIO_OUT_R...

Nice!

It's my prefered option to work with micropython powered MCU (ESP8266 ad ESP32)

It make the process of writing code for micropython alot easier thant everything I have tried before.

Thanks

Thanks Roberthh for your reply, I've found another post with a reply from you for the ESP8266: https://forum.micropython.org/viewtopic.php?t=5736 I get the point but I still have a hard time to make it work. import machine machine.mem16(0x3FF44008) Traceback (most recent call last): File "<stdin>", ...

Hello, Is there a way to set severals Pins values synchroniously rather than sequencialy ? In other words, is it possible to change Pin(1) and Pin(2) value in the same time ? My specific use case is to change microstepping configuration of a drv8825 while motor spin. Mode2 | Mode1 | Mode0 | STEP MOD...
