heya, I'm having a heck of a time getting a ds2438 onewire device to work on a 16f84a. I can't seem to get it to work worth anything. there are samples for other types of code in the onewire family, but I can't seem to modify the code example to work. I've got a 4.7k pullup resistor hooked up as per the example, but I have no code to let me know how to time it. also theres only one device on the bus..
