Summary of change:
I'm trying to connect HALL to both primary and secondary inputs on my development board. http://www.vems.hu/files/FredrikJagenheim/hall30.jpg '''Trigger1:''' Pin is connected to IC by 10k R55 and shorted SJ2. It's protected by a 5.1V zener on D14 and a short on D13. It's pulled up by a 10k R88 and shorted SJ6. '''Trigger2:''' Pin is connected to IC by 10k R91 and shorted SJ5. It's protected by a 5.1V zener on D27 and short on D24. It's pulled up by a 10k R59 and a short on SJ7. '''The result''' The board boots, but doesn't run lcd_update. Stuck in primary/secondary trigger handler? This happen even if I disconnect the trigger pins; so I guess I've botched the pull-up. I have; the signal should look like this 'hall signal -> pulled up by 10k to 5v -> 10k series resistor -> 5v1 zener to ground -> ic1 pin'. Thanks, Dave.
