    Problem with Edsion mraa Gpio speed

    lzyun

      I wrote the c code on edison with mraa library to control GPIO through mini breakout kit.

      but the result couldn't meet the requirment for me.

      I need the gpio to read and to ouput in about 50us.(I try to read the sensor ds18b20)

      Is there any possible way to speed up the reading or i just need to change to the arduino breakout kit?

      thanks,
