4.2 Functional Description

The I2C-USB Bridge is connected to the PC in the same way as an HID device. It requires no

additional driver when connected to a PC installed with Windows. This I2C-USB Bridge works as a

master in the I

C bus and is controlled by the PC program via USB. In addition, a demonstration PC

program is included with the project to demonstrate bridge operation with connected I2C slave.
