Atmel AVR Propeller Clock

Posted January 9, 2012 by Chris

“Each time the PCB passed at 12h00 a hall effect sensor sensed the magnet and generated an interruption. At this time, we have to check the counter to see how many ticks had been passed from this rotation since the last rotation, took this value and divided it by 360. This calculation then gives you the time between each degree.”
