This page is about '''building your own procedure trainer device''' using basically [[FlightGear]], other OpenSource software and home brew hardware. It is probably far from being a FNPT [http://de.wikipedia.org/wiki/Flight_and_Navigation_Procedures_Trainer Flight Navigation Procedure Trainer ], so I'd like to call it a '''PMPT''' for ''Poor Man's Procedure Trainer''.

The goal is to have most of the components, "real" FNPT have:

The ATMega8 itself needs a firmware before it is usable for our PMPT and to be recognized as a USB HID device. The source code for the firmware is mostly written in C and can be compiled with the avr-gcc toolchain. To get the resulting binary into the controller, no special programmer hardware is needed as long as you have a computer with a [http://en.wikipedia.org/wiki/Parallel_port parallel port]. [http://www.captain.at/electronics/atmel-programmer/ Here] is a description of the required interface - just two resistors and five wires between your computer and the controller do the trick.

Your best friend for programming the ATMega is a dude called [http://www.nongnu.org/avrdude/ avrdude].
