hello guys, i want to use a reed switch like an on/off switch but also as selector.
i have connected it in a pull up resistor and to a pic16f88 port. the use i want to make for example is 3sec the magnet to the switch then system on if i release and put the magnet again for 3 sec there then it is becoming off, but if i dont release then after 4 sec (3-on+1) then is selecting mode A, 5 sec (3-on+2) then is selecting mode B and 6 sec (3-on+3) then is selecting mode C till i release. in the system program im checking a sensor and is in 4 mode silent (on state) 15sec ring (mode A) 30sec ring (mode B) and last 60 sec ring (mode C)
i have problem in ho to use the on-off and the mode selector code... any help with it?
 

To do this analog fashion, you can start charging a capacitor when you press the switch. Apply its rising volt level to a 3914 IC (bargraph). The output pins will go through your various choices, in sequence one at a time.
 

there isnt any way with the delay? for example
for (; {

if (porta.f1==0){
on=1;
delay_ms(3000);
if (porta.f1==0 && on==1) {
.....
...
}

something like this?
 

Sorry, don't know the syntax of that programming language.

It's a good idea to display what is the potential choice at each moment. That is, what you would select if you let up the switch.
