This package provides EPICS drivers for the some of the USB I/O modules from Measurement Computing. Currently the USB-4303 counter/timer module and the USB-1608G-2A0 analog input/output module are supported. Each of these drivers is documented separately.
This module is currently only supported on Windows, with the win32-x86, windows-x64, and cygwin-x86 EPICS architectures. The driver uses the Measurement Computing "Universal Library", which is only available on Windows. Measurement Computing does not offer Linux support for the USB-4303. They do have a new message based library they call DAQFlex, which runs on Windows, Linux, and Mac. It currently only supports a few of their newer modules, including the USB-1608G series. The software architecture of this package is quite nice, and the source code for the drivers is provided. Unfortunately it is implemented in the C# programming language. C# is supported on Linux and Mac OSX with the "Mono" compiler package. My understanding is that it is difficult to call C# from C/C++, which is what the rest of EPICS is written in, and for this reason I have not used DAQFlex in this EPICS module. In principle one could rewrite the C# drivers in C++ and then use this new API with EPICS on Linux, Mac and other platforms that have an underlying USB library.
