would you mind explaing how your set up works for me please pommie as i would hate to mess the bug up as i am starting to like it in a odd kind of love/hate relationship lol

, and i got the following errors

. its a great bit of kit i am still a little cautious with it as i tend to be a little heavy handed and the last thing i want to do is kill it lol. is probally one the best purchases i made last year and trust me i made a few :d btw happy new year everyone
, i would use another compiler but to be honest i paid soo much for this one i am reluctant to just discard it. cheers in advance and sorry if it seems like i am just having a moan
void main() {
PORTB = 0 ;
TRISB = 0 ;
while (1) ;
PORTB = ~PORTB ;
Delayms (1000) ;
}
as an example i took the following code from there web site
Code:void main() { PORTB = 0 ; TRISB = 0 ; while (1) ; PORTB = ~PORTB ; Delayms (1000) ; }
and i get 6 324 Undeclared identifier 'Delayms' in expression C
so what basic noob mistake am i making
