Undefined identifiers when using NHET

Dave Saggs

Hi,

I am using the TMS570 Microcontroller Development Stick, with a TMS570LS20216 MCU (ASPGEQQ1).

I have a short NHET program using CNT and MCMP to generate a clock output via NHET pins.

I am getting the following errors:

#20 identifier "CNT_INSTRUCTION" is undefined
#20 identifier "HET_MEMORY" is undefined
#20 identifier "HET_MEMORY" is undefined
#20 identifier "MCMP_INSTRUCTION" is undefined
#71 incomplete type is not allowed

The last error I think is because of the previous errors.

regards,
Dave

Hi Dave,

Were the HET files generated through any TI tools ?

Hi Pratip,

I have not used any TI tools to generate the code.

The .HET file is as follows:

L00: CNT{next = L01, reg = A, max = 6};
L01: MCMP{next = L00, reg = A, en_pin_action = ON, hr_lr=HIGH, pin = CC24, action = PULSEHI, order = REG_GE_DATA, data = 0x3, hr_data = 0x60};

I have generated the .c and .h files by running the NHET assembler (hetp.exe) on the .HET file above.

regards,

Dave

Hi Dave,

You have to include the std_nhet.h file in your project. This header file is placed in the same place where you have the Nhet assembler ( hetp.exe).

By Default it can be found in ..\Texas Instruments\Hercules\NHET Assembler\std_nhet.h

Hi Prathap,

I have the header file included.

I have noticed that I was copying the NHET program to NHET RAM twice, after removing the second copy the project compiles OK. Thank you for your help.

Regards,

Dave
