CC1312R: DAC output

Hi Yolande,

It's not clear to me what you're trying to do. Can you please re-phrase and specify what you mean by " I want to get the data from the radio out of DAC. " What data is this? Is this the IQ data or the payload?

Are you seeing an issue with the dacoutputbuffer example, or is there missing functionality?

Cheers,

Marie H

Hi Marie

I didn't see the sine wave of the DAC output when I burned the dacoutputbuffer example。

Hi Peter,

The picture above shows the jumper lines are not connected. Can you double check the following? (This is from the readme.)

• Example output requires the use of an oscilloscope connected to the output pin and a jumper wire to connect the ADC’s input pin to the DAC’s output pin.

• Connect CONFIG_DAC_0 to the oscilloscope probe and CONFIG_DAC_1 to CONFIG_ADC_0.

• The oscilloscope should show the sine wave output from CONFIG_DAC_0 with a frequency of 60 Hz.

Cheers,

Marie H

Hi Marie,

Isn't the sine wave output by DAC0 defined in code? I just want to see the output of DAC0 now, can I use the energy trace to see the output curve, or do I want to use an oscilloscope connection to see it?

Cheers，
