I'm currrently on a project with the 4WD rover. I'm planning to use the SABERTOOTH 2x5 controllers and my microcontroller is a TMS320F28069.
Why not use one of the many "supported" ones, well, I used this one a lot and I like it. Plus, I already wrote most of the libraries already in another project.
Thing is, I'm kinda new to motor control and I read the user guide and saw that I could use a PWM output with a Low-Pass filter to control the analog input of the sabertooth.
Will the motor speed be controlled with the duty cycle of my signal ? (0-49 = reverse, 50 = stop, 51-100 = forward)
And will the frequency matter much, as long as I'm over 1kHz (recommended in the guide)?
Thanks a lot
I attached an image showing a block diagram of the output circuit to show what I want to use.
