CCS compiler easy answer I think... |

I have been getting myself familiarized with the CCS IDE and compiler and was trying to get the basic blink a light project working and for some reason I get the weirdest error when compiling. It indicates there needs to be a closed ")" at the end of "output_low(yellow)" and "output_high(yellow)" but that makes no sense after looking over the documentation and videos. I hate to be posting such a simple question but I don't know what else to try, I've been adding () and {} all over the place hoping to catch this simple mistake but it just makes no sense.
Code: |
#include "C:\Documents and Settings\Garry\Desktop\CCS trial\blink_light.h"
#define yellow PIN_J5;
void main(){
while(TRUE){
output_high(yellow);
delay_ms(1000);
output_low(yellow);
delay_ms(1000);
}
} |

Look closely at the #define statement. What happens if you put the
defined symbol into the output statements ? |

WHAT?!?!!? ok now I'm lost, got the little bugger to compile but I thought I was assigning "yellow" to J5, what is going on here? Also much thanks for the info but now it leads to more questions. In the examples I've seen they show that the syntax I'm using should be correct to "name" my output pin. |

Your define syntax is incorrect for what you are trying to do. Remember, EVERYTHING (except for comments) after the word yellow gets put where the word yellow is found. Do the substitution on a piece of paper and see what output_low(yellow); looks like with the substitution. |

I will most certainly be re reading the library files, and give that substitution a run through. So weird when you change compilers (was using mcc18) all the things you used to know are still valid but with a little twist. After I run through the substitution I will then be headed down the rabbit hole to see if I can make my ICD 3 program my board. Thanks for the input, do appreciate it. |

Code: | #define yellow PIN_J5;
#define yellow PIN_J5 |

The fault, would give problems with _every_ C compiler in existence.....
