Summary of change:
I'm trying to connect HALL to both primary and secondary inputs on my development board. This is what I've figured out: http://jagenheim.se/hall-3.0.jpg The red areas are +5V, probably good to use as pullups. Trigger 1 is the magenta area; it needs a resistor (not pictured) at the voltage regulator to get there. It should connect to the cyan area, which is the input pin on the atmega. Trigger 2 is the Yellow area; it should connect to the Blue area. Does anyone have a good idea on how to make all these connected? * connect HALL to IC1 and IC3 traces * apply pullup * Recommended to apply some (diode) protection, eg. 5.1V zener (SOD80 D14 and D27) so IC1 and IC3 get clamped. On a production circuit this is a must. *trigg2= R91 stuffed, D24 should be a short, and D27 a 5.1V, zeener SJ5 shorted *trigg1=R55 stuffed, D13 short, D14=5.1V zeener, SJ2 solderd http://www.vems.hu/files/MembersPage/FredrikJagenheim/hall-3.0.jpg
