Re: PWM Microchip Blocks in Simulink - dsPIC33EP512MU810
Blocks input are integers and do not represent physical values.
In your case, the PWM input block must be scaled.
The blockset set a Variable PWM1max in your Matlab workspace.
PWM1max value represent the max duty cycle (here 0.0001s).
Multiply your physical value (in s) with PWM1max, connect the result (unsigned integer) to your PWM block.
As Cristi mention, you could find others examples, either on this forum, of within the blockset. (type picInfo and follow links to copy examples in your working folder)
