The CodeInfo Structure/Class represents all aspects of a code except for the data. This is used when learning and when transmitting codes.
 
* '''dataLength:'''      The length of the code data in bits
* '''encoding:'''        The encoding used for the data. Possible values are: Space, Pulse, Bi-Phase, RC5 and RC6
* '''length:'''          Whether the code length (including gap) is constant or variable.
* '''gap:'''              The gap time. For constant length codes this is the entire code time including the data and the gap, for variable length codes, this is the gap time only.
* '''trail: '''          Trailing bit time.
* '''header:'''          Header pulse and space. Specify 0 for no header.
* '''zero:'''            The pulse and space used to identify a ‘0’ in the bit stream.
* '''one:'''              The pulse and space used to identify a ‘1’ in the bit stream.
* '''repeat:'''          The repeat code. This must start and end with a pulse and be terminated with a 0 (null).
* '''min_repeat:'''      Minimum number of times to repeat the code.
* '''toggle_mask:'''      The toggle mask. These bits are toggled when transmitting.
* '''carrierFrequency:''' The carrier frequency in Hz. Default is 38000. Range is 10kHz - 1MHz
* '''dutyCycle:'''        The period of the carrier frequency. Default is 50. Range is 10-50.
 
Depending on the encoding used, most of these can be set to 0/null to select default values.
 
===Functions===
 
{{UGapi|Transmit(Byte[] data, IR_CodeInfo codeInfo)
|Transmits a code.
}}
 
{{UGapi|TransmitRepeat()
|Transmits a repeat for the last transmitted code. Note that this function must be called before the gap time has elapsed since the original code transmission, or the repeat code will be transmitted too late.
}}
 
{{UGapi|TransmitRaw(int[] data, int offset, int count, int carrier, in dutyCycle, int gap)
|Transmits a raw data stream of length count starting at offset, at a specific carrier frequency and duty cycle, with a microsecond gap after the data is sent. Carrier, duty cycle, gap, count, and offset can be set to 0 to specify default values. The data array must start and end with a pulse (have an uneven number of values).
}}
 
{{UGapi|int ReadRaw(int[] data, int length)
|Reads up to a specified amount of raw data in the data buffer. If no data is available, returns 0, else returns number of ints read. Read data always starts with a space and ends with a pulse.
}}
 
{{UGapi|Byte[] LastCode() [get]
|Gets the last code received. If there is no last code, this will throw the EPHIDGET_UNKOWNVAL exception.
}}
 
{{UGapi|(Byte[], IR_CodeInfo) LastLearnedCode() [get]
|Gets the last learned code. Returns both the code and a CodeInfo structure/object. If there is no last code, throws the EPHIDGET_UNKNOWNVAL exception.
}}
 
===Events===


{{UGapi|Code(Byte[] data, int bitLength, Bool repeat)
|The code event is fired every time a code is received and correctly decoded. The data array has a length 1/8 of bitLength with the MSB being in position 0. MSB is considered to be the first bit received. Repeat will be true if a repeat is detected - either timing wise or via a repeat code. False repeats can happen if two separate button presses happen close together.
}}
{{UGapi|Learn(Byte[] data IR_CodeInfo codeInfo)
|The Learn event fires when a button has been held down long enough for PhidgetIR to have learned the CodeInfo values - usually about 1 seconds, or after 4 repeats.
}}
{{UGapi|RawData(int[] data)
|The Raw Data event will fire every time the PhidgetIR gets more data - at most once every 8ms.
}}

Revision as of 19:48, 29 August 2016


Required Hardware

  • A 1055 PhidgetIR
  • An IR remote control and the appliance it controls
  • A USB Cable
  • A computer

Connecting the Pieces

File:1055 0 Connecting the Hardware.jpg
  1. Connect the PhidgetIR to your computer using the USB cable.


Testing Using Windows

Phidget Control Panel

In order to demonstrate the functionality of the 1055, 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 1055.

First Look

After plugging the 1055 into your computer and opening the Phidget Control Panel, you will see something like this:

1055 Panel.jpg


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.

IR

Double-click on the IR object, labelled PhidgetIR, in order to run the example:

IR Example.jpg


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

  • The Show RAW Data checkbox toggles the RAW data window. This window lets you see incoming codes as pulses and gaps (expressed as numbers in milliseconds). You can also re-transmit this raw data.
  • IR Code: the hexadecimal code corresponding to the signal just received.
  • Repeat Count: how many times the same code has been received in a row. If you hold down a button on most remote controllers, it will continually transmit repeat codes.
  • Bit Length: the length of the code in bits.
  • When a code is repeated multiple times, the {{{1}}} will learn the code. It will display the relevant information in the Learn box. For more information, see the technical section.


You can read more about IR remote controls in our IR Remote Control Primer.

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

Consumer IR

The PhidgetIR can send and receive data encoded in various fashions as pulses of infrared light. The various encoding that the PhidgetIR supports are grouped under the general term ‘Consumer IR’ or CIR. CIR is generally used to control consumer products such as TVs, DVD players, etc. with a wireless remote control, but in general can be used for any application that needs to transmit low speed data wirelessly.

CIR is a low speed protocol - commands generally contain no more then 32-bits of data with a bit rate of at the most 4000 bits/second, but usually much less. There is no concession for anti-collision, so only one code can be transmitting at any time. Transmission distance depends on the power of the transmitter, but needs to be line of sight - though generally this can include bouncing off walls/ceilings, etc.

CIR data is transmitted using a modulated bit stream. Data is encoded in the length of the pulses / spaces between pulses, of IR light. The pulses of IR light are themselves modulated at a much higher frequency (usually ~38kHz) in order for the receiver to distinguish CIR data from ambient room light.

Further Reading

You can read more about IR remote controls in our IR Remote Control Primer.

What to do Next

  • Programming Languages - Find your preferred programming language here and learn how to write your own code with Phidgets!
  • Phidget Programming Basics - Once you have set up Phidgets to work with your programming environment, we recommend you read our page on to learn the fundamentals of programming with Phidgets.
