I am trying to control a motor card using Raspberry Pi support package. Has anyone done this before? I am using the mdd10a control board which requires a PWM signal as well as a left vs right boolean signal. Any help would be appreciated.

Hi Shima,
To do this, you can use 2 GPIO pins on the raspberry pi. Please refer to the following link for the overall workflow:
1. All the pins support PWM, configure a pin for PWM using configurePin
2. Write Duty cycle and frequency to that pin. Refer to the example here:
On the other pin, you can write the boolean flag you want using writeDigitalPin
Hope this helps

Hello! Thank you for your note. I am using Simulink and I was able to use pins 17 and 22 for PWM and DIR (direction) to control the motor. The issue I am encountering is that despite changing the available settings on the PWM generator block, the motor moves at a steady state. In another words, varying the duty cycle does change the speed of the motor but does not slow it down as much as needed. any ideas?
