I'm sorry to keep asking hardware questions on the owfs-software-dev list, but I don't know where else to ask these things.
Why do all (that I've found) light-measuring circuits based on the DS2438 use reverse-biased photodiodes, rather than, say, a photoresistor? Either way you could have a fixed sense resistor between the Vs+ and Vs- terminals. I ask because I'm having trouble getting a photodiode to work correctly, and I can model a photoresistor using a potentiometer to make *sure* it's working the way I expect it to.
