I have several ideas now. I am using a vb.net program I wrote using the DS9490 to talk to 1-wire network. If I could use serial I would but I am looking at a way to bit bang a protocal just for pic communication using a .dll. If I do this it could be a cheap way to talk to pics using a ready made usb link in the DS9490. I will post the code if I do this. I am also looking at the DS2423 but it says "Do not use for new designs".
I guess I could use a DS2405 to latch a pin on a pic then write to a memory 1-wire using master mode then read the data. This seems excessive.
Thanks for all the Ideas.
