Introduction

Model 526 is controlled through a set of registers mapped into I/O space of a PC-compatible

system. Interrupts can be handled, if necessary, by setting up an interrupt vector which points to

the interrupt processing function (handler). Those tasks are relatively easy in the environments

that allow I/O operations from the application level (for example, DOS).

Some operating systems (for example, Windows) are more restrictive in terms of hardware

access. Under most versions of Windows even a simple I/O access (port read or write) is not

allowed directly from the application software and has to be performed by a driver. For this

reason Sensoray provides a Windows SDK (Software Development Kit) for Model 526, which

includes a driver component, and a DLL which contains necessary board control functions.

Sample applications are provided to illustrate the use of the SDK.

Some useful functions are provided in the form of C source code. Those may be used with minor

or no changes under various operating systems and development platforms.
