PicBasic - TMR0 16F877 - dino308gt4 - Oct 30 17:24:00 2002

I'm using PicBasic and my project requires taking an analog reading
every 100th of a second.
Is using TMR0 the best way to do the timing?
It looks like the prescaler ratios do not make it possible.

Even is written on picbasic or not, you have at least two good options:

a. tmr0 with rollover, it works with a good prescaler and tmr0 initial
value "100th of a second" 1/100 = 10mS
b. tmr0 in free running, start tmr0 and count the number of counts (
including prescaler ) until the tmr0 is equal with a comparison number.
( you have to count also the delay need for comparison by extra
instructions )

regards,
Vasile
