Other Parts Discussed in Thread: TMS320C6670

Dears,

I'm working on the TMS320C6670 Evaluation Module DSP which I want to interface with another kit via SPI.

I have read the document of the SPI and I was searching a lot about examples for it but I didn't find any thing.

Do you provide an examples for SPI ?

Thanks in advance.

    Hi Maha,

    You can use SPI with external device. 

    Please refer the evmc66x_spi.c file description before using it. You may need to modify this file for other external devices.

    Thanks.
