TMS320F28379D: How to have a shared pre-processor in CPU and CLA

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hello , What is the correct way to have a common pre-processor variable compile for both the CPU and CLA.

I have a preprocessor

#define ADC_TYPE 0

It is used in both the main CPU and a CLA task to set some initial configuration , I define it in a header file and the CLA does not seem to be able to recognise it, when the source complies.

    Hello,

    As long as you have included this header file inside of your CLA file, you should be able to reference any defines from the header file inside a CLA task. If you take a look at some of the examples in C2000ware they do something similar, for example in the cla_ex1_asin example ([C2000ware install]/driverlib/f2837xd/examples/cpu1/cla), TABLE_SIZE_M_1 is defined in cla_ex1_asin_shared.h and used in a CLA task in the asin.cla file.

    Best Regards,
