LAUNCHXL-F28379D: How to get all the 12 ePWMs of LAUNCHXL-F28379D at its physical pins

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

Tool/software:

Hi there,

I'm new to TI processors coding through CCS. I purchased Launchpad F28379D(336 pin ZWT package) considering its high ePWM count of 12 numbers. But I am able to activate ePWM1 to ePWM6  easily by careful filling GPIO structure. After struggling a lot, able to activate ePWM8 whose GPIO pins are GPIO14 and GPIO15 whose pins are available at pin 73 and 74. 

Ref. for above image. at page 20.

Ref. for above image. page 9.

Similarly I found out the physical pin for ePWM12A(not for ePWM12B) as pin 8 and for ePWM10A(not for ePWM10B) as pin 4. I searched out in TI forms and other resource on HOW TO GET ALL EPWM SIGNALS AT THE PHYSICAL PINS, but didn't find the helpful content.

This LINK conveys that LAUNCH PAD doesn't provide physical pins of all the GPIOs and suggest to work on TMDSCNCD28379D (Dock board). Is it true that  Launchpad just provides only subset of TMS320F8379D features?. If not why there is Dockboard with this chip?. Is it possible to access all ePWMs of this chip using Launchpad?.

    Hello Tharun,

    Based on the Quick Start Guide and schematic, it seems that LaunchPad does not bring out ePWM7 and above, which is mostly the case with LaunchPads. Dock board or controlCards are more sophisticated EVMs in that term. They are used for reference designs, and they are integrated into system design solutions.

    The EVMs like controlCard and especially low-cost LaunchPad are used for evaluation of C2000 MCUs by leveraging a flexible and modular ecosystem. It has a bit of everything, so it does not aim to add all ePWMs. You could try TMDSCNCD28379D, it should have more features, but I don't think it drives all ePWMs either.
