The Functionalities of Create USB Interface

The CUI board was designed based on the PIC18F4550 microcontroller in order to function as a musical interface, a novel visual interface, an ultrasonic ranging device, or a game controller.

One of the general I/O ports if PIC is normally used by the CUI and for user applications to be built in the prototyping area, the remaining ports are available. A versatile PIC18F4550 microcontroller is the heart of the board which features an efficient RISC-like instruction set, 18 general I/O ports, and 13 A/D inputs.

A variety of applications can be created using the PIC and CUI board. As a musical interface, an interactive composition or performance setup can be controlled by programming the CUI board to convert analog sensor inputs to a standard USB protocol. As an ultrasonic ranging device, the outgoing pulses are generated sufficiently fast by the PIC where the results are accurately measured. As a game controller, a game pad is enumerated where the PIC is programmed to behave as a joystick type device. As a novel visual interface, the input from a sensor can be measured by PIC and the user input is interpreted by host computer.
