MSCAN driver and PE code generation. compile error in msCANdrv.h:expected identifier before numeric constant

[saya]

Hi, all,

I am trying to load the msCAN driver into my project these days. I enabled Processor Expert and generated code, but when I include the msCAN drivers, I encountered this error:

Description	Resource	Path	Location	Type
expected identifier before numeric constant	msCANdrv.h	/MSCAN_KEA128/MSCAN_DRIVER/CAN_inc	line 98	C/C++ Problem

I have tested the msCAN example without PE code generation, it works without any error. Thus I am guess there are some redefine in the generated code that cause this error, but I can't find any.

I attached my project here, any enlightenment is appreciated!

Alan

hi Alan,

I open your project with CW10.6. generate pe code then build. I saw "expected identifier before numeric constant" error stopped at ERR_OK line in enum definition in msCANdrv.h.

the problem is ERR_OK is already defined in PE_Error.h:

#define ERR_OK

0x00U /*!< OK */

thus if you define it again in enum format in msCANdrv.h. CW produces error.

does this answer your question?  if yes, please click the Correct Answer button. Thank you!

Have a great day,

Thanks, Jennie! I knew it was define somewhere else but I can't find it! Thank you for pointing that out!
