RedRat SDK

The RedRat SDK is intended for the development of applications based on RedRat technology or to support its integration into third party systems. The SDK supports irNetBox and RedRat3 using .NET on Windows OS and irNetBox using Mono on Linux (from V3.04 onwards).

Using the SDK

Windows Prerequisites

  • The .NET Framework 4.5.1 or higher.
  • RedRat.dll – V4.15.zip
  • RedRat hardware. This is actually optional, but only minimal testing will be possible without hardware.

Instructions

Reference the file RedRat.dll in your .NET project to access its API. Several sample projects show the basics of using RedRat devices. Sample .NET Code (C#, VB.NET, VC++) Download (zip)

  • SimpleSignalOutput: Shows how to find a USB RedRat3 device, load an IR signal database file and output a signal from this file via the RedRat3.
  • RR_CLI: A command line program for the output of IR signals, described in more detail here.
  • SignalDecoding: Demonstrates the code needed to handle input IR signals from the RC detector on a RedRat3, decode them and perform an action as a result. In this case, a small window is moved around the screen using cursor keys on a remote control.
  • CustomSignal: shows how to construct a couple of IR signals, and then save them in the standard Signal DB Utility XML file format so that you can load them into the Signal DB Utility for further use.
  • irNetBox-III-Demo: Shows how to output IR signals via the irNetBox-III. This uses both the old synchronous API (sending one signal at a time, which is applicable to older irNetBox versions) and the new asynchronous API which supports sending multiple, different IR signals from the MK-III irNetBox.
  • VB-Net-Sample: A small VB.NET application that tests many RedRat3 functions to show API use with VB.NET.
  • VC++_NET_Sample: Shows use of the RedRat API using managed VC++.

Code Examples

Take a look at various code examples giving an introduction to using the RedRat SDK.

  • USB RedRat device naming changed to RedRat-N, which is common to MK-I and MK_II RedRat3s.
  • Moved registry key storage of device information from HKLM to HKCU so that there are no warnings when RedRat code is run on Vista and Win7 in non-Admin mode.
  • Added support for the irNetBox-III.
V2.30 – 19 Oct 10
  • If an irNetBox is discovered twice (e.g. two network cards in PC) then only one is added to list of devices.
  • RedRat lookup and irNetBox output group lookup is now case insensitive.

  • All device finder methods now return LocationInfo objects rather than string names.This may require changes to application code.
  • Added further support for irNetBox-II output power levels:
    • IROutputChangedEventArgs now uses power state rather than just boolean values.
    • IROutputGroup also uses the OutputPower enumeration rather then bool on/off values.
  • COM API supports the use of the USB irNetBox-II.
  • Many other bug fixes and small improvements.
V2.20 – 8 May 08
  • Supports RedRat3-II, i.e. MK-II versions.
  • DoubleSignal.SignalLength() returns the length of the longest signal, rather than 0.0.
  • RedRat3USBImpl: When RCOneShot was set, and there was an error when disabling the RC detector then a background, unhandled exception would be generated. This now fails quietly.
  • RedRat4 XPorts IP versions can now be set as being found directly by IP address.
V2.06 – 1 Feb 08
  • Minimum fuzz length on RedRat3 can now be set to 0 when used with Firmware V0.33 or greater. This gives faster length processing on signal input.
  • Added XMP-1 signal decoding.
  • Added RC5 signal generation from system/command codes.
  • Added DO_TOGGLE_TIMEOUT to SignalDataCache so that the A signal will always be used following a certain timeout period.
  • RegistryKeyValue code changed to open HKLM reg entries as read-only if it can’t open as read/write.
  • CCWRedRat3 & CCWRedRat4: Learning signal input, when cancelled or timeout, the event wasn’t passed through the CCW layer, so never arrived.

  • Allow DB XML file to be opened read-only mode through the COM interface.
  • When a RedRat3 was unplugged while the RC detector was enabled, exceptions would be generated in a very tight loop, causing high CPU and memory usage. This has now been throttled.
V2.05 – 25 June 07
  • Added a function to COM interface to allow unhooking of RedRat events prior to application shutdown. This prevents a COM error raised when the application is closed. See VB6 sample for details.
V2.04 – 12 June 07
  • Ported the SDK to .NET 2.0
  • Added support for USB irNetBox
  • The irNetBox can now output flash type IR signals

  • Validates the X5 version of the XPort is in an irNetBox, i.e. looks for the RedRat ID in XPort setup records.
V1.22 – 4 Dec 05
  • Default signal decoder still not always picked up. Now fixed.
  • On RR3 object initialisation, do not now insist on reset of endpoint 2. If another application was inputting via this RR3 it meant that this second application could not start.
