Need a code example of slave spi-dma for 21262

I need a code example of SLAVE SPI-DMA for ADSP-21262 (in C).

In the examples supplied with the VisualDSP installation disk, there are only Master examples.

  • Hi Gad,

              I have tested your code on the ADSP-21262 EZ-KIT Lite board. I have used ADSP-21469 board as master for this purpose. I have done some modifications in the code to send two buffers of data from the ADSP-21262 SPI slave to the ADSP-21469 master.  I could see that the data is sent properly from the ADSP-21262. Please refer the attached codes for the master and slave codes.

    I can see that the first word is received correctly. Please refer the attached VisualDSP++ screenshots.  I would suggest you to use this code on your setup and let me know whether you face any issues.

    Best Regards,
