Paul,
I now have a DS9490R USB driver and the DS1820 works fine, so its a timing
issue in my PIC code written in C from a Maxim app note. Someone has
suggested reducing the 4.7k pull-up resistor so I'll try that.
Thinking a bit more, maybe I should use one of the DS2480B driver chips
instead of bit-banging?
That might be easier, or even a LINK, which is actually a PIC. There are
also PIC-basic circuits that bit-bang 1-Wire.
What is your eventual goal?
