Joystick Interfaces - This is a very simple circuit to interface a current loop sensor to an input which is designed for a voltage, such as that from a standard potentiometer. This page is technical so that interested persons can build the circuit themselves, but 4QD can also supply the interface on a 'postage stamp' sized (22mm x 27mm) board as shown in the first diagram. It is a relatively trivial circuit! __ Designed by Richard Torrens
Joystick Interfaces - This is a page of analogue interfaces for joysticks. Although these interfaces have been developed for use with 4QD's controllers they will have plenty of other uses. Also because of the development history, we have printed circuit boards available (either fully populated and tested) or bare boards) for these interfaces. __ Designed by Richard Torrens
PC Games Port Tester - So your joystick dosen't work? Is it the games port, a software problem or the joystick itself? This simple device will tell you if the games port is OK.___ SiliconChip
PC Thermometer using PC Game Joystick Port - A method of measuring temperature using the PC Game port. Display is via the program dialog or in the System tray. V2.2.5 supports timed FTP to a web server __ Designed by andrew AT AndysWorld
Soundcard Joystick Port problem solver - Typical PC soundcards (for example Sound Blaster family) has added MIDI interface to the joystick connector by using pin 12 for MIDI output and pin 15 for MIDI input. This causes sometimes problems with some joysticks and adapters which work pefectly on standard joystick port. The following conversion circuit enables standard joystick Y-cables __ Designed by Tomi Engdahl
The Wire Between Multiio Card & Joystick Connector - Some PC multi-IO cards have a 16 pin header in the circuit board which is wired to the joystick connector (fitter to other slot place) using flatcable. The wiring is straight one-to-one connection but, due to the different numbering scheme of the gameport connector vs the 16-way header, the pin numbers don't necessarily match (pin 16 in header is ocource lef not connected because joystick connector has only 15 pins) (Design Idea 07/03) __ Designed by Tomi Engdahl
Use PC Joystick Port to measure temperature & light levels - PC joystick port can be used very easily for simple measurement of light and temperature values. All you need for light measurements is to connect a LDR resistor between +5V and potentiometer input. For temperature measurements substitute the LDR. __ Designed by Tomi Engdahl
Using the Joystick Port as General Purpose Input - The joystick button inputs can be used as general purpose button or switch inputs, and can also be driven by logic level signals or by open collector or open drain logic outputs. If used with a signal direct from a mechanical contact (e. g. a switch, microswitch, contact, or pushbutton) , remember that the joystick port does not perform hardware debouncing, so this must be provided by external hardware or provided by software __ Designed by Tomi Engdahl
