MinimalModbus is an easy-to-use Python module for talking to instruments (slaves) from a computer (master) using the Modbus protocol. Example code includes drivers for Eurotherm and Omega process controllers. The only dependency is the pySerial module. This software supports the ‘Modbus RTU’ serial communication version of the protocol, and is intended for use on Linux, OS X, and Windows platforms. It has been tested with Python2.6, Python2.7, and Python3.2.
The lxi-control application is a command line utility for remote controlling LXI enabled devices. Typical devices include instruments such as power supplies, oscilloscopes, digital multimeters, signal generators, etc. The devices are controlled by sending SCPI commands via a LAN IP network to the devices. LXI is the successor to GPIB.
Multiple Devices Proxy is an application proxy to communicate with pipes, serial ports (RS-232/RS-485), TCP/IP, and potentially all devices in a host computer via TCP/IP sockets. It supports multicast and communication isolation. Any server may have many resources, e.g. 2 pipes, 4 RS-232, and 2 connected sockets to another server. Clients may ask for 1 to many of these resources, and all data will be multicast.
CANpie defines a Standard API for access to the CAN (Controller Area Network) bus. The API provides functionality for ISO/OSI Layer 2 (Data Link Layer). The CANpie driver is the base for HLPs like CANopen, DeviceNet, J1939, etc. Through its low memory footprint, CANpie can be used for embedded applications (without any OS) as well as for Linux. Access to the Linux CAN driver is via a socket interface (AF_CAN).
Push Puppet Toy is a computer-controlled puppet that stands to attention when a friend joins an IRC channel or comes online on IM, and collapses when he leaves. The concept is very similar to the Availabot (http://availabot.com/), but works under Linux. Schematics, firmware for the puppet, and plugins for Gaim and XChat to control the puppet are provided.
E-Badge Ticker is a tool for programming LED name badges using an IR (infrared) transmitter under GNU/Linux. It should work without major changes on almost all other Unix variants. This software has been created for the inFactory E-Badge IR sold by the German hardware/software/etc. supplier PEARL Agency. As the PEARL brand inFactory seems to be OEM reselling this product, it is very likely that this program will work for other devices.
