Hello TI team,

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

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?
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.

Hello Omer,

Thanks for your concern.

Please connect with an SD card expert.

Let me know about data logging in the micro SD card with the SPI protocol.

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.

Thanks.
