[HARP] Motor sensor

I’ve been busy for two and a half days with a “personal development” project but this afternoon with Alexandre we made a program for our motor sensor. It will run the STM32 of our class PCB with ChibiOS. To do so we use an EXTI reacting to a rising edge from our sensor. A time measurement feature allow us to get the time in micro seconds between each rising edge. That way we will be able to configure exactly the speed of our motor to eventually make it spin at 16 rotations per second. Tomorrow we will all three work on the Gumstix.
