Problems with 12F675

Also, for the Voltage conversion ...

The way you are doing it will overflow the variables and isn't very accurate.

A better way would be to use DIV32 ...

CHECK :
  ADCIN 3, ADVAL
  VT = ADVAL * 5000  ; 5V with 3 decimals
  VT = DIV32 1023    ; / maximum A/D reading

  IF VT > 550 THEN
    GPIO.5 = 0
    GPIO.0 = 0
  ENDIF
RETURN

hth,

THANK YOU !!!!
I will try the soft and I will keep You inform.

I write this code. It's something wrong :
- if I press but1 and rel1 goes low because of 'check' (over-load detected), but2 don't work not at all (must disconect power), and rel1 goes high only after two press of but1 ;
- if I press but2 and rel2 goes high, if I press but1 rel2 goes low ;
- if I press but2 and rel2 goes low because of 'check' (over-load detected), but1 don't work not at all (must disconnect power), and rel 2 goes high only after two press of but2.
Can help me ? Thanks in advance.
btw: The 'check' subroutine works fine !

OOPS, my fault

In post #5 the line

        GP3PressDone     ;   we're done

Should have been

        GOTO GP3PressDone ;   we're done

That's how it get's out of the loop under those conditions.

Sorry,

[fratello]

...still not work proper...same bugs

In your LAST version, you missed the LOW statement.

if but1=1 and rel2=0  then
         high rel1 
         pause 20
                          
         while but1=1
         call check
         wend
         pause 20
                                       
         while but1 = 0
         call check
         if rel1=0 then
            GOTO Btn1PressDone
;         pause 10
         endif
         wend
         LOW rel1

         while but1=1
         wend
         pause 20
endif
Btn1PressDone:

Thank You so much for help !
I think this is my worst project ... I damage two PIC, now I have just one, and this project don't work, even with so much help...I write so many lines of code but nothing works right...
This is the last version. Bugs:
-if press but2, ON/OFF rel2 works fine, but if I press but1 after but2, then rel2 goes OFF and nothing works more, need to disconect power
-if press but1, ON works, without OFF ; after OFF because of 'check' nothing works more, need to disconect power.
This is one nightmare !!!
Hope I don't became verry, verry boring...and I am really sorry about my english...
