VEE for UD - Windows
Keysight VEE examples for the Windows UD library. The Windows UD library is the high-level Windows library/driver for the LabJack U3, U6 and UE9. For other LabJack devices, go to the Software page.
Refer to the text file in the .zip for more information.
Updated December 1, 2010: Added I2C and Tick-DAC examples. Requires UD driver 3.24+ to work.

Example Package
UD Library Overview
First read the general overview of the UD library.
The UD driver has a handful of functions, many with the same 4 to 6 parameters.
Functions
The main functions are used to build a list of requests (Add), execute the list (Go), and read the result of each request (Get). Some functions (e.g. eGet) combine a single add/go/get into one function call.
Parameters
The parameters are described at the bottom of the Overview page. The meaning of each parameter should be apparent (e.g. Channel is the channel number you are operating on), but when it is not the pseudocode section of the device's datasheet has the extra information needed.
Handle: Always the handle.
IOType: Always the IOType.
Channel: If something besides a channel number the pseudocode section will tell you.
Value: Always the value.
X1: Usually not used, but if used the pseudocode section will tell you.
UserData: Usually not used, but if used the pseudocode section will tell you.
Pseudocode
Device specific pseudocode can be found in the device datasheet pseudocode section (U3/U6/UE9).
