System and method for converting radio control transmitter and joystick controller signals into universal serial bus signals
First Claim
1. A Universal Serial Bus (USB) adapter system for converting an analog and a digital signal from a joystick into the USB format, the system comprising:
- an analog port for receiving the analog signal from the joystick;
a digital port for receiving the digital signal from the joystick and supplying the digital signal to a bus;
an analog to digital converter for converting the analog signal received at the analog port into a converted signal and supplying the converted signal to the bus; and
a USB interface engine for receiving the digital signal and the converted signal from the bus, and for converting the digital signal and the converted signal into USB format data.

Abstract
A device for converting joystick controller generated analog and digital signals into Universal Serial Bus (USB) format, or for converting imported pulse position modulated (PPM) encoded signals from an external radio control (RC) transmitter into USB format data. The device is used, in an embodiment, for controlling simulated RC model aircraft as displayed, for example on a personal computer screen through the use of computer software. In an embodiment, the device includes a pair of two-axis gimbals, an auxiliary channel control potentiometer, and various control key switches to generate analog and digital joystick type signals as a result of direct manipulation by a user. The device also includes microcontroller circuitry for importing PPM signals, such as PPM signals generated by a commercially available model aircraft RC transmitter, to a USB port signal for interface with a computer.
