The QSB software enables users to explore various features of the QSB product.
This download includes the US Digital Device Explorer which utilizes the new .Net US Digital Device Library to scan for US Digital devices and display device specific configuration and status panels. US Digital devices are added to and removed from the US Digital Device Explorer by listening to plug-and-play events.
The US Digital Device Library provides a framework to communicate with all US Digital devices.
NOTE: The latest release of the US Digital Device Explorer setup now includes the latest release of the FTDI drivers (2.08.30).
The following items are also included in the download:
Note: On Windows 7 PCs, the first time a QSB device is plugged in, the Device Explorer should be run as admininstrator in order to allow the COM port's Latency Timer to be reconfigured to run at optimum speed. Right-click on USD Device Explorer shortcut and select "Run as administrator".USDDeviceExplorerSetup_25.EXE
The QSBFirmwareUpdater.exe provides the ability to update the firmware on a QSB device. The latest available firmware is embedded in this program.
NOTE: The latest update of the QSBFirmwareUpdater provides the ability to communicate with QSB devices at multiple baud rates. This feature is only available for QSB devices that support firmware version 13 or higher.QSBFirmwareUpdaterSetup_0.EXE
The initial release of the QSB Scope application configures a QSB-M device to stream analog input every 1.95ms and digital input when the input value changes (also limited to every 1.95ms). The resulting input is then displayed to look much like a basic oscilloscope.
The QSB Scope is capable of displaying 1 channel of analog and 4 channels of digital input. Any single channel can be configured to trigger a synchronized screen capture on a rising or falling edge. Basic trigger modes supported include auto, normal, and single sequence.QSBScopeSetup_8.EXE
The file qsb-helloworld.c is provided as a demonstration of how to
communicate with the QSB in a Linux environment. It was tested using Ubuntu 9.10 (Karmic Koala) but should work similarly in other Debian-based distributions.
The program configures the QSB to read an encoder in quadrature mode and count up to 500 pulses before restarting at 0. It then polls the QSB for updates in the count and displays them in a loop until the user ends the program using Ctrl-C.QSB Linux Example.rar
The QSB_S LabView 2009 demo utilizes the USDQSB.dll .Net library to access an attached QSB device and read the encoder count value and perform basic encoder configuration. Note: the US Digital Device Explorer must be installed before this demo will work. Extract the QSB.zip file to your LabView user.lib directory.QSBLabView.zip
This download contains the 64 bit version of the USDigital.dll, USDQSB.dll, AGauge.dll, and USDigitalExplorer.exe.USDigital_64bit_version.zip
