Multiple button press at a time.

[7hills]

Dear All,

I want to press two buttons at a time to do something but no luck. Pls see my code below. Im doing this due to I/O shortage. All individual codes are working perfectly except two button code.

Again:
 
  If PORTB.0 = 0 And  PORTB.1 = 0 Then ' this is what im trying to do but no luck.
   DelayMS 50
   Toggle LED_Green
   While PORTB.0 = 0 and PORTB.1 = 0 : Wend
   DelayMS 50
   End If
 
          ' below codes are working. 
 If PORTB.0 = 0 Then
   DelayMS 50
  Toggle LED_Red
   While PORTB.0 = 0  : Wend
   DelayMS 50
   End If
 
   
  If PORTB.1 = 0 Then
   DelayMS 50
  Toggle LED_blue
   While PORTB.1 = 0  : Wend
   DelayMS 50
   End If

Try this because your getting locked up in the wend loop

If PORTB.0 = 0 And  PORTB.1 = 0 Then ' this is what im trying to do but no luck.
      While PORTB.0 = 0 and PORTB.1 = 0
     DelayMS 100
     Toggle LED_Green
    Wend
    End If

Hello.. Thanks for the reply. But still not working. instead its going to single press code and activates portb.0 and portb.1 individually. (LED blue and RED..Whichever button pressed first)

Regards.

Sorry for my basic, test it


Again:
 
 
 If PORTB.0 = 0 Then
   DelayMS 200 'max delay between double key press
   If PORTB.1 = 0 Then
     DelayMS 50
     Toggle LED_Green
   Else         
    DelayMS 50
    Toggle LED_Red
   EndIf
   While PORTB.0 = 0 OR PORTB.1 = 0 : Wend
   DelayMS 50
   End If
 
   
 If PORTB.1 = 0 Then
   DelayMS 200 'max delay between double key press
   If PORTB.0 = 0 Then
     DelayMS 50
     Toggle LED_Green
   Else         
    DelayMS 50
    Toggle LED_blue
   EndIf
   While PORTB.0 = 0 OR PORTB.1 = 0 : Wend
   DelayMS 50
   End If
