Exodriver: Linux (kernel 2.6+) and Mac OS X low-level LabJack U12, U3, U6, UE9, Digit, T4, and T7 USB library 2.07 and C examples 01/17/2022 [email protected]

This package contains the liblabjackusb 2.07 USB library for low-level U3, U6, UE9, Digit, T4, and T7 USB communications and C examples for select LabJack devices.

Refer to the INSTALL.Linux or INSTALL.MacOSX file for library requirements, installation instructions, and compiling information (library and examples). Note that the Exodriver requires the libusb-1.0 library.

Library source code files are located in the liblabjackusb directory.

C examples are provided for the LabJack U12, U3, U6, and UE9 in the examples directory. They demonstrate basic open/write/read/close operations using the liblabjackusb library and low-level function command-response. Low-level function documentation can be found in Section 5 of the LabJack U12, U3, U6, and UE9 User Guides. The u3.h/u6.h/ue9.h, and u3.c/u6.h/ue9.c files contain helpful functions for opening/closing USB connections, calculate checksums, retrieving device analog calibration information, etc. There are 5 "easy" functions (eAIN, eDAC, eDI, eDO, eTCConfig and eTCValues) that are similar to our Windows LabJackUD driver's "easy" functions. All other .c files are examples.

USB command-response times for the U3, U6 and UE9 can be found in section 3.1 of their User's Guide and were tested with the Feedback low-level function. USB Stream times are in Section 3.2. These times were measured in Windows and are similar in Linux and Mac OS X.

Examples are not provided for Digit, T4, or T7 devices in this package. Please refer to the LJM library package and documentation for their API.

The U12 also has a high-level library, which requires this library (liblabjackusb), that provides the same API as the U12 Windows driver. It can be downloaded here:
