The Create USB Interface or also known as “CUI” is the new technique for computing that generate music and visual arts. By using CUI, it allows you to bind physical processes or actions to corresponding digital expressions.

The CUI provides the necessary electronics to capture sensor input or control actuator output. For your information, the CUI is coming with a USB port, a power LED, a Reset switch, a Programming switch and a prototyping area.

The PIC18F4550, a versatile microcontroller is used as the main heart of the CUI board. The PIC18F4550 features thirteen A/D inputs, eighteen general I/O ports and an efficient RISC-like instruction set.

Normally, the CUI uses one of the PIC’s general I/O ports, while the remaining ports are available for user applications to be built in the prototyping area. Honestly, the total cost of the CUI is around $30 per piece.

With a PIC and CUI board, you can do many useful things:

A musical interface: The CUI board can be programmed to convert analog sensor inputs to a standard USB protocol.

A novel visual interface: The PIC can be used to measure input from a sensor, such as an accelerator.

An ultrasonic ranging device: The PIC is good enough to generate outgoing pulses and measure the result.

A game controller: After a small programming, the PIC can behave as a joystick-type device.

Beside of the above tasks, you still can do many other things with the CUI board…
