About the
Low-level API
The low-level API provides direct access to the DAQBIOS protocol structure and
registers in C. The low-level API is intended for speed-optimization, when
programming unconventional functionality, or when programming under Linux or
real-time operating systems.
When programming in Windows OS, however, we recommend that you use the
UeiDaq high-level Framework API (see
). The Framework extends the
low-level API with additional functionality that makes programming easier and
faster.
For additional information regarding low-level programming, refer to the
“PowerDNA API Reference Manual” located in the following directories:

On Linux systems:
<PowerDNA-x.y.z>/docs
