I have a Raspberry PI2 with Adafruit MotorHAT, and two stepper motors attached to the hat. I have installed the Cymplecy GPIO7 on my Raspberry Pi 2, and I tried to control the stepper motors with it, but I cannot. I set the AddOn variable to MotorHAT, and send broadcast message "motor1speed20" but nothing happens.
Does anybody know anything about how to control stepper motors using scratch in such an environment like this? Does GPIO addon supports this adafruit motorhat?
