TMDSPREX28335: Regarding onboard DAC pin numbers

Other Parts Discussed in Thread: C2000WARE

I want to use the 2 DAC pin given on the explorer board for my Digital to Analog Converter.
Please, anyone, provide me with the pin number of the DAC pins on the board.

Thankyou

Best Regards

Please reference the schematic found in C2000Ware.

The F28335 Device does not have a DAC. The PREX board has 2 PWM DACs setup. These are connected to ePWM1A and ePWM2A.

Thankyou so much.

I am stuck with DAC is it possible that you can help me with codes?

I believe the example software is located here: https://www.ti.com/lit/zip/sprc875 However I am unable to verify this due to IT security policies.

It is still unclear to me if a DAC code example exists. This fundamentally is just a PWM waveform driven by these pins, PWM examples can be found in C2000ware here: C:\ti\c2000\C2000Ware_4_01_00_00\device_support\f2833x\examples
