Register Level Programming for OEM Customers
The Measurement Hardware Driver Development Kit (MHDDK) provides development tools and a register-level programming interface for NI measurement hardware. This package is designed for customers who are developing custom drivers or require nonstandard OS support. The MHDDK exposes the register map of each supported device and provides examples for completing common measurement and control functions.
Please contact your local field engineer to discuss support options as standard phone and e-mail support are not available for the NI MHDDK. You can find community support in the DDK discussion forum and the DDK User Group.

Download LabVIEW Files
All Measurement Hardware DDK files needed for register-level programming development in NI LabVIEW are installed with the version of NI-DAQmx Base which supports your version of LabVIEW.
Note: The last version of the NI-DAQmx Base driver available for download is 15.0. Please check compatibility for Windows, Linux, and macOS for supported versions of this driver. Starting in 2018, NI-DAQmx for Linux is included with the NI Linux Device Drivers. For more information, please read the End-of-Life Announcement for DAQmx Base Driver.
NI-DAQmx Base is written in LabVIEW and was created using the Measurement Hardware DDK. This makes the driver itself is an excellent source of example programs and documentation.
In addition to the examples installed with NI-DAQmx Base, the following LabVIEW examples are available for download:
