Assembly example of a multistate switch

[No1Daemon]

Hi there

I am doing a project of a timer device using a PIC12F683 and I am struggling to implement code to do 2 different functions for the same switch

I have 2 switches, Switch A on GP4 and Switch B on GP5. I want it to work like this

Switch A short press call increment timer routine
Switch A pressed and held call Low voltage cutoff routine
Switch B short press call Activate timer set by Switch A routine

Can someone please help me to work this code out using either an ocerflowing timer or a flip flop method which I have read about(or another if you have an easier method)

Thanks
Steve

This is for the following config of switches..."When switch is activated, pin goes low". Dont forgot to add debounce delays....

loop:
btfss PORTA,1
goto short
call delay //long delay
btfss PORTA,1
goto long
btfss PORTB,1
goto activate
goto loop

short:
for short press of PORTA switch

long:
for long press of PORTA switch

activate:
for short press of PORTB switch

So I can simply set up a 1 second delay as a subroutine and change PORTA etc to GPIO,4 and GPIO,5 in my case correct?

Thanks for that, I didn't realise it would be so simple.

Exactly...and put the debounce delay atleast 50ms...
