I want to use eCAP peripheral in DSP TMS320F28377D, but the datasheet omits the pins of all eCAP ports.

Which ports should I connect to have access to eCAP1..6 inputs?

Hi Nedais,

I guess you're using the Experimenter's Kit, refer these docs:

2465.TMDSCNCD28377D_180cCARD_pinout_R1_1.pdf

Hi Nedais,

On the F28377D device, you can configure any GPIO to be an eCAP input.

Take a look at the INPUT X-BAR part of the GPIO section of the F28377D TRM for more information.

If you want to output a signal (like APWM mode) from an eCAP module you will need to use the OUTPUT X-BAR to do bring the signal to an IO pin.

===

Hopefully this helps.

Thank you,
Brett
