EVAL - ADUCM350 - DAC

Hi,

Information about the use of DACs and ADCs can be found in the Hardware Reference Manual. We also provide several example codes to help users to start using the ADUCM350's feature. I'll recommend checking the amperiometric example project where there is a routine to change DACs from one level to another, and then an ADC conversion at the end.

Hi Mark,

   How to use DAC of ADuCM350 for generating the arbitrary waveforms, and also obtain the raw data of the ADC without the sequencer? 

Thanks!

Hi,

Without the sequencer, you will have to directly read and/or write to the registers that control the DAC and ADC. 

If you want to follow the sequence examples in the ADuCM350 Hardware Reference Manual (Rev. E) (analog.com), you can reverse the process the process on how it is implemented in sequencer mode. Please refer to this App Note for more details on the sequencer - AN-1293 (Rev. 0) (analog.com). It should be easy enough, here's an example. The command 0x8A000034 in sequencer would translate to writing 0x0034 to address 0x40080014. 

For ADC, it might be a bit more complicated than this but the raw ADC result can be access from AFE_ADC_RESULT register.

Hi Mark,

  Many thanks!

So can you give me an example to directly operate the DAC  for generating the arbitrary waveforms?
 

Best wishes!
