TMS320F280025C: how to use DAC to output to a pin in 280025

Quentin Fu

Part Number: TMS320F280025C

280049 has DAC, but does 280025 have DAC? I can not find it.

Although CMPSS contains internal DAC, but "The reference 12-bit DAC output is internal only and cannot be observed externally" according to the Reference Manual

Then how to convert a digital number to analog signal and output to a pin so that it can be observed with Scope? Please point me to an example project.

Thanks,

Quentin

Hello Quentin,

No, there is no dedicated DAC for this device, please see tha C2000 Peripherals Guide. The CMPSS DAC is the only version of a DAC available for this specific device.

I will let the CMPSS expert help with using that specific DAC.

Hello Quentin,

Thanks for your patience.

As Omer mentioned, unfortunately this device doesn't have a DAC peripheral so you can output it on a pin.

Regards,

Hadi
