US Digital Device Explorer (READ ME file)

This download includes the US Digital Device Explorer which utilizes the .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 A2, QSB, and T7 devices.

NOTES:

  • The QSB demos included in this setup are written to communicate at the default baud rate of 230400 bps. If a different baud rate is required, use the US Digital Device Explorer to change the device's baud rate.
  • The latest release of the US Digital Device Explorer setup now includes the latest release of the FTDI drivers (2.12.36.1). 

The following items are also included in the download:

  • USDDeviceExplorer.exe: The US Digital Device Explorer Application version 1.0.46.0.
  • Documentation includes: QSB Application Examples.pdf, QSB Commands List.pdf, USDigitalLibraryHelp.chm, SEI Absolute Encoder Communication Protocol.pdf, and SEI_Serial_Encoder_Interface_Bus.pdf
  • A2HelloWorldVB2010 - This demo provides a simple VB2010 form application that demonstrates how to open a single A2 device object and listen to count change events.  The demo allows the user to select a COM port and address, connect or disconnect, and reset encoder count.
  • A2Read - The A2Read example is a CSharp command line example that displays one or more A2 encoder counts depending on the device addresses supplied as command line parameters.
  • A2ReadMultipleVB2010 - This demo provides the ability to view multiple A2 devices, enter a description and scale factor for each device, and log sample data to a file.
  • A2SimpleConnect - CSharp form example that displays a list of available COM ports. Allows a user to select a COM port and connect to an A2 device. Displays product and version information along with the current encoder count.
  • CPRQuickCheckForQSB - C# demo that displays the number of counts between index.  This demo can be used to verify the counts per revolution (CPR) of an encoder.
  • QSBCommandDemo - simple vb.net example that allows a user to connect to a device and issue read or write commands and view the response.
  • QSBCommandLine - a C# Commandline demo that displays the current count upon startup. When bit 2 transitions from low to high the counter value will be captured and displayed.
  • QSBCPPDemo - simple C++ console application that a connects to a device and reads and displays the QSB counter value. The COMx port must be passed in as a command line parameter.
  • QSBDisplayCountVBdotNet - VB.Net form example that displays a single dial showing the encoder count.  Uses the DeviceManger to automatically find that attached device.
  • QSBDLLTester - A VB6 demo that provides a simple user interface that communicates with a QSB using the QSBUser.dll C library.  The QSBUser.h, QSBUser.lib, and QSBUser.dll are included in this demo and can be referenced by other development environments that can make calls to a C DLL.
  • QSBExcel - This demo utilizes VBA and the QSBUser.dll to connect and read a QSB device from a macro enabled Microsoft Excel file.
  • QSBHelloWorld - C# command line example that displays the encoder count. Uses the DeviceManger to automatically find that attached device.
  • QSBMeasureCPR - C# example that reads encoder counts and translates count to a distance in feet.
  • QSBMeasureTheDistance - C# example that reads encoder counts and translates count to a distance in feet.
  • QSBReadMultipleVB2010 - VB.Net example that captures the encoder count values from multiple QSB devices and logs the collected samples to a file.
  • QSBSampleCSharp - C# form example that displays a single dial showing the encoder count.  Uses the DeviceManger to automatically find that attached device.
  • QSBSampleVBdotNet - VB.Net form example that displays a single dial showing the encoder count.  Uses the DeviceManger to automatically find that attached device.
  • QSBSaveCountExcel - a C# demo that displays the count for multiple QSB devices and has the ability to log samples to an MS Excel spreadsheet.
  • QSBSimpleConnect - C# form example that displays a list of available COM ports.  Allows a user to select a COM port and connect to a QSB device.  Displays product and version information and displays the encoder count.
  • QSBVelocityAndAcceleration - C# example that reads encoder counts and calculates speed and velocity.
  • T7HelloWorldConsole - C# command line demo that demonstrates how to connect to T7 devices in Standard communications mode and displays the device information for each device found.

QuickCheck (READ ME file)

CPRQuickCheckforQSB.exe or “QuickCheck” provides the ability to test the output of any incremental encoder with Index with a QSB-S or QSB-D device.

To use the program, follow the steps below.

  1. Plug your QSB into a USB port on your computer
  2. Connect the 5-pin latching connector (for QSB-S) or 10-pin latching connector (for QSB-D) into the QSB device
  3. Connect the other end of the cable to the encoder
  4. Open the QuickCheck app
  5. Enter the expected CPR in the “Target Value” field
  6. If measuring CPR (counts before quadrature) leave “Measure CPR” checked; if measuring PPR (counts after quadrature), check the “Measure PPR” box.
  7. Spin the shaft on the encoder so that it passes index at least twice to start the count

The background color of the app will switch to green if the value you entered for CPR or PPR matches the encoder’s output. If the box goes red, the value entered doesn’t match the encoder or the encoder being tested is not performing to spec.

Note: The “Invert Counter Direction” checkbox reverses the default rotational position from CCW to CW.

QSB Scope (READ ME file)

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.

QSB Linux Demo (READ ME file)

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.
