Using Servo Block with Simulink IO
显示 更早的评论
Simulink IO currently supports the PWM output block in Normal mode, but I need to control a servo. The PWM output is at 1Khz, but a servo typically uses 50Hz. Is there any way to change the PWM frequency? My servos don't recogize 1Khz. I'm currently using a second Arduino to down convert 1Khz PWM to 50 Hz, but of course slows down the real time simulation.

Hi Jeff,
With Simulink IO, it is not possible to change the PWM frequency.
But for changing PWM frequency in external mode or deploy to hardware, there is a workaroud.
Use this Simulink library to change frequency on Arduino AVR boards. Note that this workaround will not work for Arduino ARM boards like Due/MKR1000.
Request for supporting variable PWM frequnecy on arduino is under consideration.

Hi Jeff,
The feature is available in R2020a.
