1-wire lurker

From EWiki

Jump to: navigation, search

Dallas Semiconductor has this great bus called 1-wire that allows you to hook up a bunch of different sensors, A/Ds, D/As, and GPIO to a microcontroller port pin and put them tens of meters away. There are master drivers out there for every CPU imaginable, but no client drivers. I have a large network throughout my house for temperature monitoring, but I can only put Dallas/Maxim chips on it.

To remedy the situation, I am in the process of creating a client driver for 1-wire on the 8051 and PIC architectures.

Status

  • Working asm program for PJRC development board that listens to the first few pulses and can identify the ROM command sent over the bus.
  • On hold until I get some motivation to work on it.

Todo

  • Write PIC version of lurker
  • Write code to respond to some ROM commands like Search ROM
