TMS320F28335: TMS320F28335

Mahetab,

        this is relatively common, you can use the sync in and sync out funcitons of the PWM. Please see this post here for more details: https://e2e.ti.com/support/microcontrollers/c2000/f/171/p/612493/2261541#2261541 .

Please note when doing this there is a small additional delay in the sync chain that you will need to compensate for, this is described in both datasheet and the following post.

Hi,

Also note that some of our newer devices, such as the F2837x (F2837*D/F2837*S), have more ePWM modules than the F28335 device.  As a result, they can output more PWM waveforms - without needing to utilize multiple devices.  These newer devices would also have more features.

If you have sufficient flexibility in device choice, these newer devices may be something worth investigating.


Thank you,
Brett
