Register-Level Programming
The final option for programming any National Instruments DAQ
hardware is to write register-level software. Writing register-level
programming software can be very time-consuming and inefficient,
and is not recommended for most users.
Even if you are an experienced register-level programmer, consider
using National Instruments application software to program your
National Instruments DAQ hardware. Using the National Instruments
application software is easier than, and as flexible as, register-level
programming, and can save weeks of development time.
