TIMER3 issues
PostPosted: Fri Jul 23, 2010 10:14 am     Reply with quote
Hi,
I need to configure TMR3L and TMR3H with 0xCF2C but it seems like this piece of code is not doing it. I also tried to use Assembly for the same reason but I can get this configured it always shows that TMR3L and TMR3H have a zero value.
The purpose of this code is to have TMR3 overflow every approx. 10ms.
CODE 1:
Code:

setup_timer_3(0xCF2C);        // 0xCF2C = 53036
setup_timer_3(T3_INTERNAL | T3_DIV_BY_1);
enable_interrupts(INT_TIMER3);
enable_interrupts(GLOBAL);

CODE 2:
Code:

#asm
 MOVLW  0xCF
 MOVWF  TMR3H
 MOVLW  0x2C
 MOVWF  TMR3L
 MOVLW  0x85
 MOVWF  T3CON
 BSF    PIE2,1
#endasm

What is the problem?

Thank you

That line should be:

set_timer3(0xCF2C);

If you have problems with CCS functions, always post your PIC and
your compiler version.
