    brushless motor (servo) control using mraa_pwm

    Thomas Kirven



      I'm wondering if anyone has been able control a brushless motor via speed controller with the mraa pwm functions on the Edison. I am able to do this easily with an arduino using the servo class, but for some reason sending the same signal from Edison using mraa pwm functions results in nothing happening.


      I have looked at the signals with an oscilloscope and they are virtually Identical. However the Edison pwm signal is level shifted to 5V and the arduino pwm signal comes directly from the board (already 5V). Not convinced the level shifting is the cause of error, but I can't think of anything else.


      I appreciate any help/suggestions anyone is willing to give!
