ljacklm: Linux (kernel 2.6+) and Mac OS X high-level LabJack U12 library and
|
||||
C/C++ examples

|

This package contains the libljacklm high-level library for the U12 and examples
|
||||
written in C. The examples demonstrate libljacklm library usage. The library
|
||||
is a port of the ljackuw high-level Windows driver, and uses the Exodriver for
|
||||
low-level USB communications. The functions are documented in section 4 of the
|
||||
U12 User's Guide and in the ljacklm.h header.
|
||||
|
||||
Refer to the INSTALL file for library requirements, build and installation
|
||||
instructions.
|
||||
|
||||
Function execution times are comparable to one ones documented in section 4.x in
|
||||
the U12 User's Guide.
|
||||
|
||||
Note to Mac OS X users:
|
||||
|
||||
The libusb_get_device_list libusb call tends to be slow, causing 900+ ms
|
||||
overhead when a device needs to be found and opened over USB. This overhead
|
||||
will be seen in your program's first libljacklm function call that communicates
|
||||
with a U12. Subsequent function calls to the U12 in the program will be the
|
||||
standard 20 ms execution time unless an error occurs.
|
||||
|
||||
|
||||
Contents of this package:
|
||||
|
||||
The libljacklm directory contains the following:
|
||||
* The libljacklm library source and header files, ljacklm.c and
|
||||
ljacklm.h, and the Makefile for Linux and Mac OS X.
|
||||
|
||||
The examples directory contains the following:
|
||||
* This directory contains U12 code examples written in C. The examples use
|
||||
the ljacklm header file installed in the /usr/local/include directory and
|
||||
the ljacklm library installed in the /usr/local/lib directory. The
|
||||
applications created from the code run in a terminal.
|
||||
|
||||
|
||||
The INSTALL file provides requirements and installation instructions for the
|
||||
liblabjackusb library, along with instructions on building the examples.
