Problems with 12F675

[Darrel Taylor]

One last problem : if press but1 and rel1 is high, how can made rel1 low, with but1 - press again, of course - OR BUT2 - press once... ?!? (and some things with but2/rel2).

I don't understand that.
Relay1 and Relay2 can never be high at the same time.

That's because of these statements...

if but1=1 and rel2=0  then

If Relay2 is on, it won't accept a press of Button1.

Or maybe I missed the point of the question.

But1 make rel1 high at first push and low at second push.
But2 make rel2 high at first push and low at second push.
It is possible this :
-but1 make rel1 high at first push and low when push second time but1 OR push but2 ?
-but2 make rel2 high at first push and low when push second time but2 OR push but1 ?
So, rel1 ON with but1 , and OFF with but1 OR but2 ; rel2 ON with but2, and OFF with but2 OR but1. Hope now You understand me;I am really verry sorry for my poor english...
Thank You !


....me again. This is my working variant !
In check: procedure I write this :
if rel1 = 1 and but2 = 1 then
low rel1
pause 500
goto Btn1PressDone:
endif

if rel2 = 1 and but1 = 1 then
low rel2
pause 500
goto Btn2PressDone:
endif
In ISIS don't work, but in fact yes ! I don't understand why, but...Maybe You have another variant, much better; it's a good way to learn more. Still don't know if rel (1 or 2) stop if overload detected, only AFTER checking this overload for 5 times...

OK, I see what you mean now.

Try this ...

btn1:                   'actionare buton up

if but1=1 and rel2=0  then
         high rel1
                                 
         pause 20
                          
         while but1=1 
         call check
         wend
         pause 20
                                       
         while but1 = 0 AND but2=0      
         call check
                  if rel1=0  then
                  GOTO Btn1PressDone
                  endif
         wend
         LOW rel1

         while but1=1 OR but2=1
         wend
         pause 20     

endif
Btn1PressDone:

And yes, the check: routine seems to work "only after 5 times".

I am speechless...THANK YOU VERRY MUCH ! Works like a charm ! Great job, You are verry, verry good in this...

I have tested this module on my car ; works verry fine, like I expect.Since this will be use on car, I think this is one good ideea to minimize the consumption.So I try to write something...Please take one advice...Thanks !

[Darrel Taylor]

I think it might be better to ...

main:
    rel1=0
    rel2=0
@   sleep
    pause 100

It looks like you have correctly set-up the pic to wake from sleep on PORT change (either switch).

So then it wakes up ... drives the motor relays as necessary ... and only after the motor is finished, and no buttons are pressed, go back to sleep.

The two NOP's are only required if it will be jumping to an Interrupt vector on wake up.
Yours is just continuing where it left off.

Hmmm, sounds like a powered antenna driver. ??

Thanks for reply ! I KNOW that YOU are right. ...Now my car has "intelligent" windows !
...I think to 'implement' the detection of 'long press button/short press button', but after one short holidays...All the best !
