Abstract

Based on the widely used USB communication technology, when the speed requirement is not too high using USB controller chip with I2C bus develops USB interface, you can reduce the use of pin microcontroller ATmega8, simplify connection circuit. This article describes the design method of a Philips company with I2C interface USB interface chip PDIUSBD11, as well as the peripheral hardware circuit connection and USB HID class program design method. The test results show that can reliably achieve communication function between USB and computer, and has good application value.
