The Universal Serial Bus (USB) is an industrial standard serialinterface between a computer and peripherals such as amouse, joystick, keyboard, etc. This application note describeshow a cost-effective analog USB joystick can be builtquickly using the Cypress Semiconductor single-chipCY7C63000 USB microcontroller. The document starts withthe basic operations of an analog joystick followed by an introductionto the CY7C63000 USB controller. A schematic ofthe analog USB joystick and its connection details can befound in the Hardware Implementation Section.
