N Nayth New Member Nov 11, 2009 #1 Hi I'm trying to understand how to make the timer1 work I have input on PORTA.4 and it pulses, and I want to check if there's more or less than 10 seconds between the pulses Code: TMR1CS = 0; //internal clock TMR1ON = 1; //enables TIMER1 T1OSCEN = 0; //oscillator is shut-off TMR1H = 0x00; TMR1L = 0x00; Then I thought I could do something like Code: if(Timer1 > 10) { //Do Stuff }else{ //Do something else } I know the above code wont work and this is where I need your help, cause I just can't seem to find any info about how to set up Timer1 and then check how far it's counted. Please write if I should supply more code

N Nayth New Member Nov 11, 2009 #2 If I set Code: TMR1H = 0xFDE8; Shouldn't it count to 65,000 and then roll over? Another questen is, why is my program slowing down when I execute this command? Code: TMR1IF = 0; That command should reset the interrupt flag for the timer, no? I'm so lost with this Timer1, please help if you can Thanks in advance

N Nayth New Member Nov 13, 2009 #3 Same slowdown if I use Code: T1IF = 0; I can't crack my head around why it slows down when I call that function There's no slowdown when I reset the interrupt bit for Timer0 Anybody have an idea? Last edited: Nov 13, 2009
