How to program Interrupt in EDMA with SPI data transmit ?(C6747)

Jeremy13304

Hi, i am a newer with c6747, it turns great differences in programing with c672x series?

and it is the first time for me to use the DSP/BIOS, it seems stranger to me a lot!

Problem is the SPI0 is used to transmit data with DMA, how can i program the SPI interrupt?

In 672x, the CSL is easier to program the interrupt service routine...

What components are needed to program c6747?

CCS, DSP/BIOS and some other tools??

Hi Jeremy,

Please look at the GSG. The C6747 does not have a CSL, but a PSP (https://community.ti.com/forums/p/2094/7963.aspx#7963). In PSP, the hardware interrupt is abstracted by the driver.

After you installed the software according to the GSG, you can find an example using the SPI (and edma) for C6747 at the folder:

C:\Program Files\Texas Instruments\pspdrivers_01_20_00\packages\ti\pspiom\examples\evm6747\spi\edma
