ExtInt not working properly

[pythoncoder]

I've now updated asyn.py to produce a better error message if uasyncio is out of date. Thanks for the feedback.

Your while True: loop will take 2 seconds per iteration which probably accounts for the slow response.

However I would consider using aswitch.Switch. There is no need to use interrupts to handle switches, and the Switch class handles debouncing and callbacks. Using that class would simplify your code considerably. A callback on each switch would update the LCD with the message appropriate to that switch.

Okay Sir. I will try that too.

Sir do you know how i can change pin configurations for stm board. Like if we see in stm32f407 disc board, UART1 pin are utilized for performing other functions. So how can i change the pin configuratuions.

Do i need to fork the micropython , then change the configuration file for stm than compile it or is their some any method ?

Thanks

This is outside my experience but you do need to fork/clone, modify and compile. You only need to fork if you want to raise a PR to include your board definition in the official build - otherwise cloning the official repo to your machine and adapting it locally will suffice.

For a start on how to do it look in ports/stm32/boards.

I've got a collection of board files here: https://github.com/dhylands/wiki/wiki/M ... oard-files

If you look at the README.md file in say the 1BITSY one: https://github.com/dhylands/1BITSY it gives the steps to install the board files into a cloned micropython repository and how to build/deploy.

To support a new board, you'll need to create a similar set of files and follow a similar set of instructions.

okay thanks Dhylands and Pythoncoder. I will revert, if i face any probs.

thankyou

Hi,

What version of Micropython are you guys working with? I do not have an aswitch module.

Code: Select all

The aswitch module is not part of MicroPython. It comes from this repo.
