To no avail . . .

Hi Everyone,
This is my first use of a 12F675, and I used some of Bruces code, to BCD control the time period from a lookup table and it works really well. I am using his code to control LED off time, But I am trying to control on time using IF / THEN loops and the code simply ignores the IF / THEN loop as if it simply said 250. If I substitute a number in the B0 variables place it uses that number. Anyone have an idea why the IF/Then loop has no effect? I have moved it around within the code to no avail.
Thank You
JS

Code:

@ __config _INTRC_OSC_NOCLKOUT & _WDT_OFF & _MCLRE_OFF & _CP_OFF

 PCON = %00000011      ' BOD off, No POR flag set
DEFINE  NO_CLRWDT 1
    OSCCAL = %1111100  '
    CMCON  = 7                ' disable analog comparators
    ANSEL  = 0        ' disable A/D module, all digital
    WPU.4 = 0          ' disable weak pull up on GPIO.4
    B0    VAR BYTE
    X    VAR WORD
   
    Index VAR BYTE
   
    LED  VAR GPIO.5   
   
    TRISIO = %00011111  ' RA0 to RA3 inputs for DIP switch
   
    OPTION_REG = %11111111

   

   
Main: 
    IF (GPIO.4 = 1) THEN
  B0 = 2500
else
  B0 = 250
  endif   
 
    Index = GPIO & $0F  ' Read DIP switch AND mask result
    LOOKUP2 Index,[200,300,400,500,600,700,800,900,1000,2000,_
    3000,4000,5000,6000,7000,8000],X
   
   
    HIGH LED
    PAUSE b0
    LOW LED
    PAUSE X
   
GOTO Main

    END
    POKECODE @$3FF, $50  ' reintroduces osscal correction data

Hi,

I note :

B0 var Byte ... and further B0 = 2500 ...

so, 255 is the maximum possible value for B0

Since you're using a 12F675, how much accuracy do you need with the delay?
If a lot of accuracy isn't needed, how about throwing a pot on a pin and using the POT command for a the delay?
It would save you 3 pins to do other stuff with at the very least, and you can still scale the delay from a low to a high end with a simple software change.

Hi Jeremy,
I might do that, this device only needs to do what it does, but those extra pins could be used for more on time options like 500, 1000, or maybe the pot command might control that.
