"WebUpon a hardware interrupt flag being set, the associated ISRs will run. I also implement a 'main loop'. This main loop is untimed in the sense that it will continuously run as fast the processor allows. Within this loop, there is a series of software flags that are checked. These software flags are set in the ISRs. " - Setting flag in arduino in ext interrupt
