MSPM0G1506: does MSPM0G150x UART support the DMA+IDLE interrupt to receive random length(1~128Bytes) datas?

Hello,

Yes, MSPM0G devices support using UART and DMA with interrupts. There are a couple code examples available in the MSPM0 SDK, which can be viewed on TI Resource Explorer. 

Please see the below links:
uart_tx_multibyte_fifo_dma_interrupts

uart_rx_multibyte_fifo_dma_interrupts

You can also view the UART and DMA academies available on TI Resource Explorer for more information on those respective peripherals.

In addition, in case you have not seen it, there is a migration guide available for moving from STM32 to MSPM0G (linked here).

Thank you,

Susan

Hello, 

It is my understanding that you are referring to the LSB-first or MSB-first data transmit and receive settings on the UART peripheral, which in that case would be yes.

For more information, please see the TRM and Datasheet sections over UART.

Thank you,

Susan
