Revision history [back]

I am developing simple board that could be integrated with Jolla and I need a way to notify Jolla that my board is ready to send data through I2C (every random interval).

I am ultra beginner with Linux, interrupts or polling and documentation is a bit enigmatic (3.2.3 INT LINE HANDLING) and I believe this is the last piece of my puzzles. I assume, that the code could possibly look like:

void interrupt_handler() {

    // Horray, my board has new data for me!
}

int main() {

    set_interrupt_listener( 67, interrupt_handler ) // GPIO 67

    while(1);
}
