General • Re: Why is it impossible to find information on Interrupt pins for the Pico?

This information is also implied by the API documentation for the GPIOs: https://www.raspberrypi.com/documentati ... ae16ab724f (enum gpio_irq_level).

I'm a little confused, because I'm fairly new to embedded. I would have assumed that GPIOs in the embedded world always support IRQs. Are there a lot of processors out there that don't support IRQs on most/all GPIOs?

There are many boards that do not support interrupts on every pin, such as the Arduino Uno, Nano and Mini.

But again they always specify in easy to find documentation, most Arduino boards interrupts can be found here for instance: https://www.arduino.cc/reference/en/lan ... interrupt/

I wouldn't say that using an easily available, searchable pdf document, written specifically to contain that kind of information, that should be a go-to when working with a device (especially unknown) is too hard either. It took me about 30 s to find that information in the datasheet, probably faster than it would if I tried to google.
