Abstract
An improved software architecture for data acquisition (DAQ) driver level software executing in a DAQ system. The DAQ driver level software receives calls from the DAQ user application and is executable to control the DAQ device. The DAQ driver level software includes one or more interpreters which receives calls from the DAQ user application. Each of the interpreters performs functionality which is common for a plurality of DAQ devices, and each of the interpreters is preferably useable for a plurality of different DAQ devices. The DAQ driver level software also includes a plurality of mini-driver primitives which each perform a portion of controlling the DAQ device, i.e., each controls a hardware resource of the DAQ device. In the preferred embodiment, each of the mini-driver primitives present the same application programming interface. The present invention thus comprises an improved architecture for DAQ driver level software. The software architecture of the present invention thus provides much greater code reuse and simplification of individual board drivers.
