TMS320F28379D: EnDat interface real requirments

Ed Sanders

Part Number: TMS320F28379D

Greetings,

We have been using the EnDat library which places the direction control pin, ENDAT_DIR on GPIO34 (sprui35). Newer documentation, tidude3a, states that it is now on GPIO9. Has it been moved, or am I missing something?

Thank you

Hi,

Earlier software (GPIO34) library was intended for IDDK hardware. So, it's fine if you continue to use that pin.
Recently released software library version was intended for BOOSTXL_POSMGR booster pack hardware.
You can continue to use what you've been using, no need to change to GPIO9.

Hi Subrahmanya,

For our new HW, we would rather use GPIO9. It seems that for our processor, the TMS320F28379D, the new library would work for us. Do you agree?

Thank you,

Yes - you could use the new library. Please look at all other pin assignments as well and make sure it works for you.
