Required Hardware

Connecting the Pieces

  1. Connect the STC1000 to the VINT Hub using the Phidget cable.
  2. Connect the stepper motor to the Phidget's output terminals. See your motor's data sheet or product page for wiring instructions.
  3. Connect the VINT Hub to your computer with a USB cable.


Testing Using Windows

Phidget Control Panel

In order to demonstrate the functionality of the STC1000, the Phidget Control Panel running on a Windows machine will be used.


The Phidget Control Panel is available for use on both macOS and Windows machines.

Windows

To open the Phidget Control Panel on Windows, find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

Windows PhidgetTaskbar.PNG

macOS

To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the Ph.jpg icon to bring up the Phidget Control Panel.


For more information, take a look at the getting started guide for your operating system:


Linux users can follow the getting started with Linux guide and continue reading here for more information about the STC1000.

First Look

After plugging the STC1000 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.


The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Stepper Motor

Double-click on the Stepper object, labelled {{{2}}}, in order to run the example: [[Image:{{{1}}}_Stepper_Example.jpg|center|link=]]


General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Toggle the Engage button to provide power to the motor coils.
  • By default, motor position, velocity, and acceleration are measured in sixteenths of a step. If you want to use different units, change the value in the Rescale Factor textbox.
  • Use the Target Position slider to set a new target position. Change the Acceleration and Velocity sliders to speed up or slow down the {{{1}}}'s approach.
  • Select the Velocity (Continuous) Control tab for continuous rotation instead of specifiying a position.


Testing Using Mac OS X

  1. Go to the Quick Downloads section on the Mac OS X page.
  2. Download and run the Phidget OS X Installer
  3. Click on System Preferences >> Phidgets (under Other) to activate the Preference Pane
  4. Make sure your device is properly attached
  5. Double click on your device's objects in the listing to open them. The Preference Pane and examples will function very similarly to the ones described above in the Windows section.

Testing Using Linux

For a general step-by-step guide on getting Phidgets running on Linux, see the Linux page.

Using a Remote OS

We recommend testing your Phidget on a desktop OS before moving on to remote OS. Once you've tested your Phidget, you can go to the PhidgetSBC, or iOS pages to learn how to proceed.

Technical Details

Power Consumption

The quiescent (idle) power consumption of the STC1000 varies depending on the amount of voltage it's supplied.

Function Calling Order

Target Position

The following functions must be called in the order in which they are numbered, or you will get a invalid sequence error. Functions on the same number can be called in any order:

  1. setControlMode
  2. setAcceleration, setCurrentLimit, setDataInterval, setVelocityLimit
  3. setEngaged
  4. setTargetPosition

Failsafe

The STC-1000_0 failsafe has the ability to hold its position even if VINT communication is disrupted. This could be caused by a disconnected cable or a program crash. To enable this feature, call these functions in order:

  1. setHoldingCurrentLimit
  2. setEngaged (set to '1')
  3. setFailsafeMode
