5.2 Example Project 2: I2C-USB Bridge Board Project

5.2.1 Project Description

This project demonstrates communication between the bridge and host. After each packet is

received by the bridge, an acknowledgement is sent to the host before the next transfer operation

begins.

This project uses the following modules:

CMPRG: Used to compare the data programmable reference threshold.

PWRFB: Used to set the power level for this application.

TIMER8: Used to wake up the application from sleep mode.
