LAUNCHXL-F28379D: number of ePWM in launchpad f28379d

Tauquir iqbal

Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: C2000WARE, TMDSCNCD28379D

currently, i could see only 12 ePWM from ePWM1A-ePWM6B . i want to use 24 ePWM I could see in the datasheet of the DSP that the number of epwm is 24.

can anyone clarify ?

Hi Tauquir,

Not every device pin has been brought out to a header on the LaunchPad, therefore you won't have access to all ePWM signals.

There are however more than just ePWM1A-ePWM6B on the LaunchPad, but the MUX options are not documented on the pinout diagram provided with the board.

For example GPIO14 and 15 are pinned out to the J8 header and have ePWEM8A/B MUX options available (see datasheet for MUX options). I believe there are some other ePWM signals available on the board like this, such as the DAC1-4 pins documented (should remove RC filters on these pins, see schematic).

Best,

Kevin

Thanks kevin.

i know all pin are not been brought out due to lower the price in launchpad.

do all pins is brought out in the experimental kit ?

can i use 24 ePWM in experimental kit

Hi Tauquir,

Sorry for the delay. You can find the schematic and pin map for the ControlCard within the C2000ware directory below:

C:\ti\c2000\C2000Ware_3_01_00_00\boards\controlCARDs\TMDSCNCD28379D\R1_3

Not every pin is brought out on the ControlCard either, however it's much more than the LaunchPad. I'm not certain about every PWM signal, you can reference the CC pinout and device datasheet to confirm.

Best,

Kevin
