Work with SPI on TMS320C6657

Other Parts Discussed in Thread: TMS320C6657

Hello,

I'm working with the evaluation kit TMS320C6657 and I need to communicate with A2D through SPI component.

As I read, there is software API in PDK for hardware components and example codes for some of them in BIOS_MCSDK_2.0_User_Guide(UART GPIO etc.) .

In addition I understand that the SPI is connected to the NOR flash memory and to the FPGA on the board, Is there any option to work with it directly through the DSP ?

Is there any example program/codes for the SPI component  ?

Thank you, 

Joni Sheingouz.

    In your case, you may need install and refer latest MCSDK 2.x. Please find the download and user guiide links below my signature.

    Thank Rajasekaran K fo your response,

    I'm already have the packages, in that packages I found the files like evmc665x_spi.c that supposed to work with the NOR memory that connected through the SPI, can I use these functions to program the DSP if I connect external hardware through these ports?

    In addition , I found files : spi.c, spi_api.c and spiutil.c at C:\ti\mcsdk_2_00_xx_xx\tools\boot_loader\ibl\src\hw\spi folder ,
    are that files useful for using SPI in the DSP ?

    Thank you ,
    Joni Shein.

    You may need configure the spi peripheral with reference to the external hardware connected to these ports.

    In addition , I found files : spi.c, spi_api.c and spiutil.c at C:\ti\mcsdk_2_00_xx_xx\tools\boot_loader\ibl\src\hw\spi folder ,

    Yes. These are all very low level init, read and write functions. You can write own wrapper functions around it to use if for the custom hardware configurations.

    Thank you.
