Timer Question 16f877

[btaylor]

Timers are often too valuable to use just to blink a LED and adding a PAUSE statement can stuff up other parts of the code. What I do for such time insensitive issues is use a loop counter and the TOGGLE command.

Activity VAR portb.0 ' activity LED
LoopCntr VAR word

MAIN:
LoopCntr = Loopcntr + 1
IF loopcntr//1000 = 0 THEN TOGGLE Activity

your code goes here

goto MAIN

Depending on your system cycle times, you can adjust the divisor to get an appropriate flash rate.

Hi Btaylor

You say that timers are too valuable to use for an led, what kind of things do you use them for generaly ?, i ask because i have not used them before and dont know what they can be used for.
In the case of the status led, i had the idea that i could somehow tell the timer to flash an led independant of my code, since charles told me how its done i dont think that will be possible, but, its introducing me to a new tool i might use in other projects.
