1203 User Guide

Required Hardware

• A 1203 Phidget TextLCD
• Sensors, LEDs, and switches to test the InterfaceKit
• A USB Cable
• A computer

Connecting the Pieces

1. Connect any sensors to the voltage inputs on the 1023.
2. Connect a switch or a piece of wire connecting ground to one of the digital input terminals.
3. Connect an LED to one of the Digital Outputs by inserting the long LED wire into the digital output 0 and the shorter wire into Ground.
4. Connect the 1203 TextLCD to the computer using a USB cable.

Testing Using Windows

Phidget Control Panel

In order to demonstrate the functionality of the 1203, 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 icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

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 icon to bring up the Phidget Control Panel.

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

• Getting started with Windows
• Getting started with macOS

Linux users can follow the getting started with Linux guide and continue reading here for more information about the 1203.

First Look

After plugging the 1203 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 If your Phidget is listed in red, your firmware is out of date.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.

Text LCD

Double-click on the LCD object, labelled {{{2}}}, in order to run the example: [[Image:{{{1}}}_TextLCD_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:

• Write in the Display text text boxes, your input will be mirrored on the LCD screen.
• Drag the Contrast and Brightness sliders to a level where you can clearly see the text on the screen.
• Toggle the Cursor and Cursor Blink checkbox to view the current cursor position on the LCD screen.
• Toggle Custom Characters to show an example of the {{{1}}} using bitmaps.
• Use the Clear button to clear the screen.

Voltage Input

Double-click on a Voltage Input object in order to run the example: [[Image:{{{1}}}_VoltageInputSensor_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:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• If you have an analog sensor connected that you bought from us, you can select it from the Sensor Type drop-down menu. The example will then convert the voltage into a more meaningful value based on your sensor, with units included, and display it beside the Sensor Value label. Converting voltage to a Sensor Value is not specific to this example, it is handled by the Phidget libraries, with functions you have access to when you begin developing!

For more information about Voltage Inputs, check out the Voltage Input Primer.

Voltage Ratio Input

Double-click on a Voltage Ratio Input object in order to run the example: [[Image:{{{1}}}_VoltageRatioSensor_Example.jpg|link=|center]]

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

• The voltage ratio is reported in Volts per Volt. For example, if the Phidget is providing 5V and the sensor is sending back 2.5V, the ratio will be 0.5V/V.
• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• If you have an analog sensor connected that you bought from us, you can select it from the Sensor Type drop-down menu. The example will then convert the voltage into a more meaningful value based on your sensor, with units included, and display it beside the Sensor Value label. Converting voltage to a Sensor Value is not specific to this example, it is handled by the Phidget libraries, with functions you have access to when you begin developing!

Digital Output

Double-click on a Digital Output object {{{2}}} in order to run the example: [[Image:{{{1}}}_DigitalOutput_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 state of the digital output by pressing the button.

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

If you want to know more about the input/output capabilities of the InterfaceKit, check the Digital Input Primer, InterfaceKit Digital Outputs page, and the Analog Input Primer. For more information about the LCD screen, see the LCD Primer.
