MSP432P401R: DMA example and UART Interrupt example using TI-ROTS

Hello LLouis,

LLouis said:

1. I only find DMA example using TI driverlib in Simplink-MSP432. While, could you suggest if we have example of using DMA with TI-RTOS;

Currently this example does not exist but we are constantly developing new examples (I already passed your request to our SW team). In the meantime, you will need to migrate the driverlib example. Please let me know if you need some help with this.

2. If I wants to add UART and register call back function for UART ISR, how I should handle with TI-RTOS?

I think it will depend on what are you planning to do. For example, I recently changed the attached UART terminal code (part of the SIMPLELINK-WIFI-CC3120-SDK-PLUGIN) from polling to a callback function. Please take a look at this code and let me know if this is what you had in mind.

David,

Thanks for response. Yes, we'll need your help on an example of migrating driverlib example to a TI-RTOS example. Could you support and let us know when we can get the example project?
Thanks.

Hi David,

I've find create_hwi() can create the H&W interrupt routine. So you can pass my second question. Just we need a example of using DMA in RTOS. Thanks.

The simplelink_msp432_sdk_1_30_00_40\source\ti\drivers\spi\SPIMSP432DMA driver uses DMA.

Todd,

Thanks for sharing. We'd like to learn how to integrate the DMA in TI_RTOS. Not register level.
