hello When you compile a program TMS320F28335 error:
Error evaluating 'InitFcn' callback of C28x SPI Transmit block (mask) 'Test_plati8_work / Tok / sample / SPI Transmit'. The SPI module SPI_Tx_A is already used by another block.
I use two SPI_A module in two different blocks, but this is what I need because 2 different units operate in different interrapt.
How to remove this problem.

Please can you update on the version of the MATLAB being used?

I'm sure this is NOT the right way to do it, but I was able to get past this error by doing the following.
When you look at the Callbacks of the SPI Transmit block:
  • Block Properties of SPI Block
  • Callbacks
  • InitFcn*It is calling a function "validateC280xSPI();"
If you then enter in command prompt: edit validateC280xSPI
You can edit this function, I just commented out line 24 where it says:
lf_registerBlockCallbackInfo(opts);
Obviously, this just makes it so that MATLAB will generate the C code (and probably disables useful error checking), but I would still be interested in a more elegant solution from MathWorks
