Real Time DAQ Linux for Humusoft's (and others) I/O devices.

This library gives an access to DAQ devices under Linux with same interface as Windows. Library has been tested under both 32 and 64 bit Linux. Also alternative Windows driver is published here.

Windows driver is compatible with Humusoft's original. The compatibility is provided through different hudaqlib.dll library. You will not need to recompile your code, only replace DLL. The Windows driver is even binary compatible with Tedia drivers - for Tedia cards. If you use tedia_ep4gxa.dll you can directly access to Tedia device without reinstalling driver.

Windows and Linux drivers grants channel wise approach to the device. Chanell wise approach allows to replace e.g. digital ports from AD-622 with TEDIA PCD-7004 or reversible without changing code in your application.

Software published here is not product of Humusoft. Please NEVER ask their hot line for support with this clone of library.

On the reverse site don't ask me for regular support of your DAQ device. Ask instead. I could help you with Linux port and new features in my Windows hudaqlib that are not present inside standard release.

Hudaqlib clone driver supports these devices:

This program only checks, whether a driver is correctly installed and runs without problems.

Matlab interface to Hudaqlib

This interface is not official one, but it is much more optimised for performance. On the other side, this code does not grant realtime access. All timings must be done by Matlab means.
