Is a timer delay accomplished with an interupt?

Hi ShortBus,

I Hope your bike is not a CB 250/350 ... no emergency brake signal needed ... cause no break at all !!! LOL ...

But ... I'd bet for a CB 750 ...

Being serious ... no interrupt needed :

a fair solution could be to use a 32.768 Khz Xtal for clock ... and let TMR 1 ( 16 Bits ) run quietly ...

that permits to use 12F683 and 16F628 as "simple" Pics.

How to ???

By polling the TMR 1 Overflow bit !!! (TMR1IF)

Let's have TMR 1 running freely : an overflow will occur after the delay you want "not to re-arm the flashing sequence" ... let it run ...

Let's use the brakes :

Overflow bit is set : engage the flashing sequence, and when releasing brakes... quit the flashing sequence and reset TMR 1 and it's Overflow bit ...

re use the brakes :

- before "Timeout" : overflow bit is clear ... continuous lighting !

- after "Timeout" : overflow Bit is set ... engage the flashing sequence !!!

32.768 Khz Xtal ??? just will need you to correct the programmed times by x 122 if using the Std "DEFINE Osc 4"

( Programmed PAUSE 10 will give 1220 ms instead of 10 ms ... so, if needed, use Pauseus :
Pauseus 1000 will give 122 ms instead of 1 ms ... )

This is just not to twist your brain on how to create " 1 - 10 seconds" delays ...
