esp32 interrupt support?

[IngwiePhoenix]

I am currently working on a little assignment in class. Basically, four buttons, four LEDs - and because I have been somewhat hyper-invested in go lately, I wanted to use TinyGo to do it.

Having sorted out my build, I can now freely work on the implementation. Well, that was untill:

tinygo/src/runtime/interrupt/interrupt_xtensa.go

Line 35 in 8c54e3d

// Warning: interrupts have not been implemented for Xtensa yet so this always

What a bummer...

Is there any roadmap or plan to add this? And, if not the esp32, which boards do have working interrupts? I am not particularily tied to that chip - it is my first MCU-dabbling basically ever - I'd rather go and buy another MCU that I can use to work with and do stuff rather than fussing about unimplemented details. x)

Thank you and kind regards,
Ingwie

Most other microcontrollers we support do have pin interrupt support. It's mainly the Xtensa ones (ESP32, ESP8266, etc) that aren't supported.

A popular board that's well supported by TinyGo is the Raspberry Pi Pico, but there are several others (from Arduino and Adafruit) that are well supported.

As for Xtensa interrupt support: I tried it, spent a few days on it, but couldn't get it to work. It's a weird architecture with very little documentation. It's possible, but not high on my priority list.

Perfectly fair. Thank you for trying though, much appreciated!

Welp, off I go to buy a Pico! Not gonna learn the whole FreeRTOS to blink LEDs, lol. (six buttons, six LEDs...my teacher is weird ^^; )
