    Problems with Galileo Gen 2 digital ouput frequency on pin 8

    MrPrezident

      I was having problems moving my stepper motor fast enough on pin 8 on Galileo Gen 2.  It looked like the output pin was not able to toggle faster than about 200 μs  (=400 μs period =2.5kHz).  I didn't check with an osilliscope, but I wasn't able control my stepper motor driver beyond that frequency. It worked fine on Arduino Uno, and also when I switch to another pin on Galileo, it works fine (right now I'm using pins 6 and 10).  Does anyone know why this would happen?
