I'm new in the Freescale world and I'd like to know if anybody can help me on the DMA Driver Framework. I'm using CW 10.5, MQX 4.1 and a TWR-K60 KIT. I need to send an SPI message every 50 microsseconds and I think that with the DMA driver it's possible to do that, but I'm not familliar (yet) with the structs and functions of the I/O drivers.
I've already read the MQX I/O User Guide. Does anybody have an example using these DMA functions (dma_init, dma_channel_claim, dma_transfer_submit, etc.) so I can understand how to implement them?
Thanks in advance.
