Blue Pill Interrupt on GPIO input state change

[olablt]

I have Blue Pill STM32f103C8T6

How to create Interrupts on 3 GPIO inputs, to fire after each state change?
Is it possible?

Here is an example Arduino code using interrupts. I am not sure how to do this with TinyGo

Hi.

I can't find implementation of (Pin)SetInterrupt for STM32 in the Tinygo sources.

So I guess GPIO interrupts are not yet available for STM32.

However, you can find some example of low-level code to configure GPIO interrupts :

• on STM32L0: https://github.com/ofauchon/tinygo/blob/lgt92_examples/src/examples/lgt92/01_button_interrupt.go
• on STM32F103: https://github.com/ofauchon/experiments/blob/master/tinygo/bluepill-misc/test_gpio_int.go

Hope that helps

Closing since GPIO interrupt support is merged
