TMS320F2806: Cannot find spi or uart example on CLA

Part Number: TMS320F2806
Other Parts Discussed in Thread: C2000WARE

Hello, I tried to access SPI on CLA on TMS320F2806, but It hangs. My question is this can I access SPI and UART on CLA on this device? I am a beginner and I did not find any example to acess peripherals on CLA. in C2000 library, there is only example to do calculations on CLA. Please help me out how to do this and whether this is possible or not?

    Hi Sanjay,

    The CLA unfortunately does not have access to the SPI or SCI (UART) modules on the TMS320F2806. To check which peripherals it has access to, you can see what the CLA Bus has a connection to in the 3.1 Functional Block Diagram section of the F2806x datasheet. I don't believe any of our devices give the CLA access to the SCI module, but some of the newer devices (like F28004x, F2837xD etc.) do give the CLA SPI access. Some of the newer device examples also have example code for interfacing with peripherals (like the ePWM and ADC) via the CLA which could be helpful to look at. These examples can be found in the [C2000Ware Install]\driverlib\f28p65x\examples\c28x\cla folder of C2000Ware.

    Best Regards,

    Delaney
