Part Number: TMS320F28335
Other Parts Discussed in Thread: CONTROLSUITE, C2000WARE

Hi everyone,

I'm working on a data logger project that is intended for sampling and transferring data to PC over USB protocol,

Interface device is MCP2210 that implement USB to SPI(Master) function, so my F28335 must be in the slave mode.

I'm looking for such a example code for F28335 Slave mode spi.

Any recommendation will be highly appreciated.

Best regards.

Hi Ali,

Download Control Suite from http://www.ti.com/tool/controlSuite

There should be some SPI examples under,

C\ti\controlSUITE\device_support\f2833x\v142\DSP2833x_examples_ccsv5\

You might need to change the examples from Master to Slave mode. I have attached the SPI Reference guide which explains how to do that in more detail.

Hi Marlyn,
Thank you for replying
I read the all related user guides and example codes in control suite and C2000ware packages before posting this question, but those are not clear enough. In the SPI user guide just one paragraph dedicated to SPI slave mode.
Is there other codes or documentation about this topic?

Ali,

There is an example for the F28004x device, but not for the F28335.

Please navigate to,

C:\ti\c2000\C2000Ware_1_00_04_00\driverlib\f28004x\examples\spi\spi_ex5_external_loopback_fifo_interrupts.c

This will give you something to look at, and is hopefully more clear.

Best Regards,

Marlyn
