Timer 0 as Counter

[Nobody/Anonymous]

Hi all. I'm trying to use hardware timer0 in counter mode on board a 16F74 to measure an external frequency.

I read the pic data sheet, and understand if I set the prescalar to 1:1 and input the signal to RA4/T0CK1 it should work?

I'm looking at the timer function commands, and I figure it should go something like this:

InitTimer0 (Ext, PSO_1/1)         ; I'll use 1/2 if necessary and
                                                 ; double the sample period

Clear timer                               ; Set to 0

Wait Sampleperiod                   ; Wait for the count to build up

Ok, now I'm at an impasse. How do I read the value of the register (Called TMRO in the PIC) into a variable so I can use it?

Thanks for any advice,

Chay

In GCBASIC a register is a variable, so you can just use TMR0 like any other variable.

Thanks for the advice.

I found the usage in the online help section.

I should have looked there first!
