Velleman K8055N peripheral controller

The K8055N interface board has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors. All communication routines are contained in a Dynamic Link Library (DLL). You may write custom Windows (XP, Vista, Windows7) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows application development tool that supports calls to a DLL. Source code examples for Visual Basic, Visual C++, Visual C#, Excel, Delphi and Borland C++ builder are available. - DIAGNOSTIC / TEST SOFTWARE: - separate output / input test - clear all / set all function - counter function on inputs 1 and 2 with adjustable debounce (max 20kHz depends on total I/O load) - analog output set sliders - analog input bar-graph indication - minimum system requirements: - 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor - USB 1.1 or higher connection - Windows XP or later
