Part Number: TMS320F28335
Tool/software: TI C/C++ Compiler
Hi all,
I am using F28335 control card. I am trying to build Matlab model for PWM(20 kHz) generation. I need a constant value and sawtooth wave(20 kHz) to generate PWM pulses. Remember I don't want to use epwm modules. I tried several ways to generate sawtooth waveform and compare with a constant value to generate pulses. None of them gave the desired frequency (20 Khz) when I saw on oscilloscope. Could you please suggest some ways to generate sawtooth waveform based PWM in embedded coder environment?
Thank you.
