TMR0 as counter

[savnik]

Thanks for yours answer.
My default PIC is pic16f88.
Maybe i change with pic18f1330 which have timer0 16bit.

Hi, Savnik

Also could eventually be useful :

the PIC freq.

The Porta.4 max input freq. to be measured

Savnik,

16F88 already has 16-bit timer.

Why change the whole car while you can change one tire and get going?

From datasheet:
---------------------------
The Timer0 module timer/counter has the following
features:
• 8-bit timer/counter
• Readable and writable
• 8-bit software programmable prescaler
• Internal or external clock select
• Interrupt-on-overflow from FFh to 00h
• Edge select for external clock

Hi, Savnik

Sayzer was only telling there's a 16 Bits timer in 16F88 : Timer 1 ...

but, if you want to use RA.4 and keep the same pinout ( must we understand PC board is already made ??? ) ... you'll have to turn to 18F1320 !

Ok , i understand
Yes PC board is already made, so i turn to 18F1320.

Thanks

Or you could just count the Overflows from timer0 and make it a 16-bit or larger counter.

Now count the TMR0 and also count the prescaler (256)

result var word ' 16 bit result of count, high from tmr0 low from prescaler
TMR0 = result.Byte1
prescaler = result.Byte0

But i cann't take the decimal numbers , only the integer
