Re: Interrupt handling

Thanks everybody for your great comments. I'll have a closer look as soon as I have time!

Interrupt handling

I have been looking in the peripherals data sheet for information on interrupts but I didn't find what I was looking for, possibly because I was looking for the wrong things. I only have some experience with interrupts on Arduino's AVR, which has a list of interrupts that can be enabled and configur...

GPIO programming

I tried hard to understand the code examples of driving the gpio pins at http://elinux.org/RPi_Low-level_peripherals#Code_examples . I must admit that I only have a vague idea of what (e.g.) a driver is. I would really appreciate it if someone could clarify and correct some things: I think I underst...

Re: GPIO power limits

Thanks! Hadn't seen that. Do you know if the datasheet this page is said to be extracted from is available for download/online viewing?

GPIO power limits

I tried looking for the power limits of the GPIO pins, mainly to be sure I don't fry my pi. Do I understand correctly that when set as "input", not much can go wrong as long as the voltage is between 0V and 3.3V? And when set as output, how much current can be safely sourced/sunk? Finally, as a refe...
