Errors on CCS 5.077 compiler and PIC24FJ128GC006
PostPosted: Sat Jun 16, 2018 9:12 pm     Reply with quote
Has anyone know why I have this error only for pin RB6, although the pin is listed in the data sheet as CN24?

enable_interrupts(INTR_CN_PIN | PIN_B6);

Error#27 Expression must evaluate to a constant :: Not a CN pin

All other pins seem to work.
thanks

You need to talk to CCS. Looks as if whoever was typing in the database for the chip managed to omit CN24.
You can potentially cheat by enabling it on another pin, and relocating it yourself, with something like:
Code:

#bit CN24IE = getenv("BIT:CN24IE")
#bit CN23IE = getenv("BIT:CN23IE")
//define the bits to access the CN interrupts.

   enable_interrupts(INTR_CN_PIN | PIN_C12); //enable the interrupt on CN23
   CN23IE=FALSE; //turn off CN23
   CN24IE=TRUE; //Now connect to CN24


A 'bodge', but ought to make it work till they come back.
