Hi,

I need help in figuring out how to transfer 16ch ADC measurements with DMA at 16.67us intervals.

Thanks in advance for your support.

Hi Arthur,

There is a ADC+DMA example in C2000ware in \device_support\f2837xd\examples\cpu1\adc_soc_continuous_dma\.

Usually you would trigger the ADC at some rate (I think 16.67us for you) using the ePWM or CPU timer, then the DMA would move the resultant samples immediately when they are complete.

Hello Devin,

Thanks very much for your response. The example helped a lot.

On another topic, is it possible to get the source code for the Code Composer library that deals with the DSP internal flash read/write/erase?

Best regards,

Arthur

Hi Arthur,

We don't provide the source code for the Flash API. All related docs and files can be found within the C2000ware directory below:

C:\ti\c2000\C2000Ware_2_01_00_00\libraries\flash_api\f2837xd

Best,

Kevin
