The Linux Control and Measurement Device Interface

About Comedi

Comedi is a collection of drivers for data acquisition hardware. These drivers work with Linux, and also with Linux combined with the real-time extensions RTAI and RTLinux. The Comedi core, which ties all the driver together, allows applications to be written that are completely hardware independent.

Comedi supports a variety of data acquisition hardware; an incomplete list may be found at

This distribution contains just the Comedi kernel modules. You will almost certainly also want to download Comedilib, which is a user space library, a few utilities, and some example programs.


For installation instructions, look at the file INSTALL.
