Part Number: TMS320F28069
Other Parts Discussed in Thread: C2000WARE

Hello TI team,

I hope this email finds you well. I am writing to request your assistance with

  1. logging data from the ADC result register in a CSV file format on a micro SD card using SPI protocol communication. Could you please guide me through the steps that I need to follow?

  2. could you please suggest any other way to log the ADC data (via DMA).

Thank you for your time and help.

Best regards,

Ram

    If you're looking to save data external to the device, the DMA will not be able to help because the intention of DMA is to offload memory writing from the CPU internal to the device. I will have an SD card expert respond to your first question.

    Ram, 

    Only bitfield examples are supported for TMS320F28069. You can refer to the SD Card examples in the following folder to use as reference and develop an example for F28069. 

    C2000Ware_X_XX_00_00\driverlib\f2838x\examples\c28x\sdspi

    Thanks.
