iButton Software

This is my iButton stack for UNIX. It's written completely from scratch and designed to be used primarily for telemetry. With it, I record and analyze temperatures from six online thermometers as well as two offline thermometers.

I'd rather write code than about code, so here's the basically what you get:

• Fault-tolerant, resiliant logging, including the last reading in an individual file by serial number for DS1920 and 1921 digital thermometers (including ``offline mode'' for the 1921).
• Network based logging via multicast group.
• Network based control via a simple asynchronous TCP server.
• A multi-threaded log collector that stores data in RRDTool and/or PostgreSQL databases. For RRDTool, this allows for complete plug-n-play operation, new devices on the bus are automatically logged as soon as the first sample is read.
• Scheme interface (via Guile) to MLan network for writing anything from device drivers (a full 1920 driver is provided as an example) to writing useful standalone applications dynamically.
• Full control utilites for 1920, 1921, and 2406.
