The Dutch-based company TRC Development b.v. announces the release of the first two versions (1 & 2) of the SimKits SDK (Software Development Kit) for the C-language. It will be released at the end of June 2003. With the use of the SDK, home-cockpit builders with programming skills can drive the SimKits hardware devices like aircraft gauges, indicators and other hardware directly from their own software via simple function calls.  Click on Read More for full article.

It is possible to read data from, and write data to SimKits devices via the CCU. Since the communication between the SimKits driver software (controlling the CCU board) and the SDK software is done via TCP/IP, you can either drive the devices from another computer over a network, or from the same computer where the CCU is installed. Using the SDK, all I/O lines of the Central Control Unit are accessible as devices (an Airspeed Indicator is a Device, like a Switch is a Device). So now home-cockpit builders can even control inputs as there are for the Yoke, Rudder Pedals, Digital Clock, Switches, Circuit Breakers, etc. The SDK does not allow them to write or read to or from individual I/O pins on the CCU.

Devices are controlled using Function Calls. For example, to position the Altimeter on an altitude of 12.000 feet, using a Function Call you write simply the values "ALTIMETER 15000". Or to set the Airspeed indicator to 98.5 Knots, you use the values "AIRSPEED 98.5".

The SDK becomes available for the following programming languages:
1. Microsoft Visual C++
2. Borland C++ Builder
3. Microsoft Visual Basic
4. Borland Delphi

As this software will be distributed free of charge, TRC Development b.v. will not give extensive support on how to write software, since programming knowledge is expected and it is up to the user how they use the SDK. However, if there will be found a bug in the SDK, full software support will be given. A special section in the forum on the SimKits website will be opened for discussions on the SDK. Tutorials and a sample programs will be supplied for every programming language.

About SimKits
SimKits is a project of TRC Development b.v. With SimKits you can build almost any gauge you want for home build cockpits to fly Microsoft Flight Simulator almost like the real thing. SimKits is build up in a way that you can use it for different types of aircrafts. The kits are made from high quality ABS plastics and come complete with all parts, screws, electronic parts, knobs etc. necessary to construct the gauge. All kits come with illustrated manuals while the difficulty level for building the kit is such that anyone can build it without technical knowledge. All gauges are connected to the Central Control Unit, which connects on its turn with a single USB wire to your PC running Microsoft Flight Simulator.

About TRC Development b.v.
TRC Development designs and manufactures realistic Flight Training Devices utilizing replicas of real instruments. The first products in a line of ATDs, FTDs and Full Flight Simulators are based upon the Cessna 172 Skyhawk, the world's most popular single engine aircraft. TRC Development b.v. was established in 1999 and is funded by private investors. The company is located at Rotterdam Airport in The Netherlands. Its products are sold worldwide via distributors and local representatives. Recently TRC Development signed an agreement with the Delft University of Technology's (TUD) Faculty of Aerospace Engineering, renowned for their accurate flight dynamics models. This collaboration enables TRC Development to deliver full flight simulators with excellent flight dynamics.
