USB Joystick

Posted on Feb 6, 2014

It makes sense to build your own individual joystick. Especially the flight simulation enthusiasts like to build cockpit parts with the look and feel of original aircraft parts. Such self made hardware needs an joystick controller that meets the requirements of the hobbyists. This project is ideal to build up devices with up to 5 axi

s and 24 buttons. It is based on the microcontroller PIC18F2455. I was inspired by a project on opencockpits. com. There is used the outdated PIC16C745 to design a similar project. The operating system of any modern PC recognizes the device as a joystick with 3 additional axis (sums up to 5 axis) and 24 buttons, not needing additional software or driver. The joystick-controller is powered and controlled via USB. The capacitors C1 and C5 stabilize the supply voltage. C2 is stabilizing the USB-voltage if the internal 3. 3V-voltage regulator. To every 3-pin-connector SV1 bis SV5 can be hooked up a linear 10-kOhm-potentiometer (the resistivity value is non critical). The sliding contact of the potentiometer has to be connected to pin 3 of the connector.
