Three programs

Short about the progress. We now have three stand alone programs (CK,SI and CI) that communicates with each other and the simulator through FSUIPC. We're still bug testing to make sure we haven't lost any functionality when we split the program into three. To communicate with each other the programs use some "free" offsets in FSUIPC that is not used by any other system we use.

The communications between the hardware (buttons, switches and numeric displays) is also handled with these offsets in contrast to emulated keyboard input as we used to have. At the moment we have an 8 bit offset reserved for key codes from the cockpit but it can easily be expanded if 256 different buttons is not enough. This progress means that I can start working on the navigation system.
