this is my programm. why is it not working? #include <XC888CLM.h> #include <stdio.h>
Timer 1 Interrupt Service Routine.
void timer1_ISR (void) interrupt 3 { while (TF1==0); TR1=0; P3_DATA=!P3_DATA; // Invertieren von P3 }
//MAIN C function
void main (void) { SFR_PAGE(_pp0, noSST); // Change to page 0 P3_DIR=0XFF; P3_DATA=0Xff;
TMOD = 0x02; /* Set Mode (8-bit timer with reload) */ TH1 = 5; TL1 = 0; ET1 = 1; /* Enable Timer 1 Interrupts */ TR1 = 1; /* Start Timer 1 Running */ EA = 1; /* Global Interrupt Enable */ TF1=0; CMCON = 12;
while (1) { } }
sorry I forgot to explain what the programm is supposed to do. i want to use the timer 1 in modus 2 (Autoreload) to synxchronise the on-off process of the leds of port3. after each overflow, the leds should change their state.
when in compile and run, i get 0 warnings, 0 errors, but Port 3 goes one time on and off, and nothing else .
i am using the mcbxc888 eval. board with ulink.
thanks
