    If you are using Linux There are no sample programs written for Linux. Go to www.phidgets.com >> Drivers Download Linux Source • Have a look at the readme file • Build Phidget21 The most popular programming languages in Linux are C/C++ and Java. Notes: Many Linux systems are now built with unsupported third party drivers. It may be necessary to uninstall these drivers for our libraries to work properly.

  • Page 9: Programming A Phidget

    Programming a Phidget Phidgets’ philosophy is that you do not have to be an electrical engineer in order to do projects that use devices like sensors, motors, motor controllers, and interface boards. All you need to know is how to program. We have developed a complete set of Application Programming Interfaces (API) that are supported for Windows, Mac OS X, and Linux.

    Functions int MotorCount() [get] Returns the number of motors this PhidgetStepper can control. In the case of the 1063, this will always return 1. This call does not return the number of motors actually connected. double Acceleration(int MotorIndex) [get,set] Acceleration is the maximum change in velocity the PhidgetStepper uses when speeding up or slowing down the motor. This is specified in the same units used for Position - in the case of the 1063, 1/16th steps.
  • Page 11 VelocityMin is the minimum VelocityLimit the PhidgetStepper can accept. In the case of the 1063, this will always return 0. Functionally, it is the minimum speed that the 1063 can drive your motor at. For very low speeds, you can increment position inside a slow software based timing loop.

    CurrentMin is the smallest CurrentLimit the PhidgetStepper can accept. In the case of the 1063, this will always return 0.0542. int InputCount() [get] Returns the number of Digital Inputs available on this PhidgetStepper. In the case of the 1063, there are 4 Digital Inputs. bool InputState(int InputIndex) [get] Returns the state of a particular Digital Input.

    At low speeds, less than 1024 1/16th steps per second, the 1063 uses a microstepping scheme to allow precise control of the current to each coil, and therefore the position of the stepper. It’s important to note that many steppers are not designed to be microstepped precisely, and will not accurately produce the expected angle.

  • Page 14: Wire Stepper Motors

    By applying current to the two coils in sequence, and changing the direction of current flow, the motor can be made to rotate. Determining how to connect a 4 wire stepper to the 1063 can be done by following this procedure. Start by measuring the resistance between all the wires. Below is a sample table of resistance data, in ohms.

    8 Wire Stepper Motors 8 Wire Motors are very difficult to wire up if you do not have a schematic showing how the wires are connected to the internal coils. Only follow these instructions if you are really desperate. In an 8 wire motor, the coils are split, and we have to reconnect the coils, to reduce them to a 4 wire.

  • Page 16: Choosing A Power Supply Voltage

    Choosing a power supply voltage The 1063 can operate from 9 to 30 VDC. It is able to reduce the voltage if your motor requires less, but it cannot increase the voltage. First, find the resistance of the coils in your motor. We will assume 4 Ohms. Add 0.5 Ohms to this to account for the electronics on the 1063. Decide the maximum current you want to push through the coils.

  • Page 17: Disabling The Phidgetstepperbipolar

    Disabling the PhidgetStepperBipolar When the stepper motor has rotated the requested number of steps, and is stopped, the coils will remain energized to hold it in position. This is necessary to allow the motor to support a load on its shaft without rotating to an unknown position.
