soft example:

Jumper is active LOW

Code:
'******************************************************************************
' check if programming jumper not forgotten ...
'******************************************************************************
 delay = 0
 BUTTON Prog,0,255,0,delay,1,mesurav
 
oubli:       ' infinite loop ... jumper MUST be placed ...
 error = 1 ' Blink the led !!!
 PAUSE 50
 error = 0
 PAUSE 50
 
 GOTO oubli
 
'****************************************************************************** 
'******************************************************************************
' Measure programming pulses
'******************************************************************************
'******************************************************************************
 
 
'******************************************************************************
Mesurav: 'Measure Forward Max pulse
'******************************************************************************
 Show = 1 ' programming led ON
 Entree = 0
 
 GOSUB Mes

Sorry, basically, all the jumper is doing is on boot it the Pic check if it is "on" and then goes into a setup mode to sense the Transmitter stick location.

What I have done this evening is resolder another board and manged to bridge accross on another PIN (one I had designed onto the same PCB for LED lighting) and got it to work. Its not "pretty" but now functional. I would still like to find a way to use the pins that are now unconnected untill the jumper is installed and then pulled up to +ve.

Worst case, is there any harm of leaving the pins floating if I am not using them for input or output? would mean I can use these PCBs for now and then fix the design in the next batch I have printed (sounds commercial, :-), not for sale but making some onboard glow / LED light drivers for some mates at the flying field.
