How to use counter in pic16f628 using picbasic pro?

Wich counter? The PIC TIMER0,1,2?

Code:

    TMR1ON=0                ' Stop counter
                            '
    CounterA.HIGHBYTE=TMR1H  ' Get results                         
    CounterA.LOWBYTE=TMR1L  '

Hi Steve,

I have succesfully set up Timer0 and Timer1 as counters individually working in the background (F877).

As I need one more counter, and went through the Data Sheet, how do I set Timer2 as a counter?

Data sheet says in "Microcontroller Core Features" that "Timer2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler".

However, there is no mention of counter in "7.0 TIMER2 MODULE" section in the data sheet.

Am I missing a key point here, and thus Timer2 can not be used as a counter from an external source?


Thanks in advance.

From what i remind, Timer2 is unfortunately just a timer and have something to do with the HPWM and CCP2 module.. not a counter. But timer0, timer1 can be used as counter.

In your case you could also use any interrupt source and increment a variable in the ISR.
