Hi Dennis,

As per the shared second link, it has SPI DMA driver changes:

the driver used in the above link is C32xx, but i am using MSP432 SPI driver.

can i get the project code or SPI DMA driver implemented code for MSP432?

Thank you,

Maniram   

Hi Dennis,

thank you for sharing the example code, i had gone through the example code, the points observed are:

1. the code is based on the non-rtos

i want to implement the DMA ping-pong using TI-RTOS, were i can configure the DMA interrupts and emulate the I2S over SPI.

2.currently i am able to use the DMA ping-pong in my current project, but unable to configure the DMA interrupt, can u please share your inputs on this?

Inputs Required:

how to configure the DMA IRQ's in TI_RTOS project?

Thank you,

Maniram
