MSP430FR6043: UART on DMA for MSP430

Vijay Simha

Hi,

We are trying to configure MSP430FR6043 UART on DMA. We see that there are not many APIs available for interrupt method and DMA method of access for UART.

Can you please provide some example code for accessing UART on DMA or interrupt method?

Thanks,

Vijay

DMA is rarely useful for dealing with serial data. It works by transferring blocks of known size and serial data is rarely that organized.

I did use it once in an application to transmit packets of data but reception used interrupts because packets were not of fixed length.
