MSP430F5333: SPI data transfer using DMA Controller

Part Number: MSP430F5333
Other Parts Discussed in Thread: MSP430F5335,

Good morning TI Community!

Today I'm here to ask you some infos about MSP430F5333/ MSP430F5335 DMA Controller.

I want to use DMA to transfer quite big data block (about 64Kb) between:

--> external RAM and uP via SPI

--> external EEPROM/FLASH memory and uP via SPI

--> I/O ports (8/16 bit) of the uP to other external devices.

Is it possible? I need to have the certainty that these setup(s) could work.

Waiting for your precious help,

Kind Regards

Luigi

  • Hi Luigi,

    Yes, you can use the DMA module to transfer data to/from the SPI module. For more information on implementing this, I recommend reading through the USCI and DMA sections of the user's guide. Additionally, there are DMA examples available in MSP430Ware. After exploring these, please let me know if you have any further questions. 

    Best regards,
