My problem is to implement a SPI master driver. Also I need to send this port many bytes (9600 bytes).

I implemented it on MK60FN1M0VMD12  by Keil environment and Processor Expert.


I can send it using a SPI by interruptions, but I would like to be able to use DMA.


This can not be done using the Processor Expert.

In addition I have seen that it is not possible to send bytes directly to the "PUSHR", because we must also complete "command information" for each byte.


Are there examples code to send a full buffer by DMA?

Is it possible without copying byte by byte with the command information?

Remember, we need to send a lot bytes continuously.


thank you!
