Push Button 'Menu' to Choose Variable.

[Tissy]

I believe it wasn't working properly due to the Interrupt settings which i have now disabled on PortB.0.

I have it working the way i want apart from one thing.

It recognises the push switch, displays the appropriate PWM and then if it reaches 9 goes to 1 again. Also, if no input for 5 seconds it starts the flashing sequence (just to signal the end of the 5 seconds).

How does one get the LEDs to stay in their PWM routine until the switch is pressed again, without using Interrupts. When the swicth is pushed it goes to the appropriate PWM routine but after the PWM cycle, the LED goes off.

Here is the code.

MyNumber    VAR Byte	' Variable 1-9
MyTimeOut   VAR Byte	' 5 second Timeout (100 loops of 50mS)

Red         VAR PORTB.1 ' All LEDs
Green       VAR PORTB.2 ' Connected between
Blue        VAR PORTB.3 ' RC pins and ground
Orange      VAR PORTB.4

DISABLE INTERRUPT
MyButton    VAR PORTB.0 	' Pin goes LOW when Button pressed

MyNumber=1		' Power-On with this starting value
MyTimeOut=0		' TimeOut starts from zero at Power-Up	

	While MyTimeOut<100
        If MyButton=0 then
			gosub mynumberpwm
            MyNumber=MyNumber+1
			If MyNumber>9 then MyNumber=1
            MyTimeOut=0
			Pause 50	
				' This Pause DEBOUNCES Button - do not remove it
			While MyButton=0:Wend
				' Wait here if Button held down
			else
			MyTimeOut=MyTimeOut+1
			Pause 50
				' This Pause is the Timeout Pause
			endif
		Wend

main:
    high Orange
    pause 500
    low Orange
    pause 500
goto main

MynumberPWM:
    If Mynumber = 1 then PWM Red,1,255
    If Mynumber = 2 then PWM Red,25,255
    If Mynumber = 3 then PWM Red,255,255
    If Mynumber = 4 then PWM green,1,255
    If Mynumber = 5 then PWM green,25,255
    If Mynumber = 6 then PWM green,255,255
    If Mynumber = 7 then PWM BLUE,1,255
    If Mynumber = 8 then PWM BLUE,25,255
    If Mynumber = 9 then PWM BLUE,255,255
Return

Many thanks,

Unless you are able to write a program with an "active real-time" loop that executes continuous PWM (I do recall posting an example of such code dimming multiple LED's continuously sometime ago), the only option you have is chosing a PIC with multiple hardware PWM.
