1-Wire Network Emulation over RS485
I'd like to create software for some Atmegas that will emulate a 1-wire network however the actual communication will occur over RS485. The goal is to allow software written for 1-wire hardware to function with this custom hardware. It will emulate 3 devices a 1-wire Master (DS2480b/ds9097u) a DS2450S (4 Channel ADC) and a DS2408 (8 channel general IO). Again the goal is for software written for 1-wire to think it's communicating with a 1-wire master and DS2408 and DS2450s devices.
Master based on Atmega164p (1 serial port connects to MAx232 and other serial port to a MAX485 or similar chip)
Slaves run on Atmega48 with max485 chip.
I maybe making this sound more complicated then it is. 1-wire software sends commands over the serial port to the master, the master then communicates commands to the slaves and relays the response back over the serial port connection.
