MSP430FR5969: Use DMA to write a certain amount of data directly to the FRAM inside the MPU

Part Number: MSP430FR5969

Hi team,

The customer would like to know if it's possible that DMA be used to write data directly to FRAM inside the MPU (for example, to FRAM from ADC memory)? And are there any related routines to reference?

If the amount of data transferred is large, is it possible to still use it to do this: for example, transfer from FRAM-block to FLASH outside the MPU.

Could you help check this case? Thanks.

Best Regards,

Cherry

    Hi Cherry,

    I suggest getting them to look at the DMA controller section of the MSP430FR596x Family User's Guide. It can provide all the information on how to use DMA.

    The User's Guide does state all memory addresses so it should be able to write to the FRAM memory address if that's what is required, though typically the data is stored in RAM.

    There are some code sections in that family user guide under the DMA controller section and we have a code example, though it is very basic. Code Example.

    I don't know about moving data outside of the microcontroller using DMA, and for large data transfers you might need to break it up into parts depending on the size. All the information will be in that User's Guide.

    Regards,

    Luke
