这个例程有助于大家理解如何通过TWI接口使得at91微处理器访问外部EEPROM。开发环境为keil。-This example program demonstrates how to use the TWI peripheral of an AT91 microcontroller to access an external serial EEPROM chip. The development kit is keil.

at91sam7的 i2c通信的温度传感器例程，iar工程例程 非常好用-at91sam7 the i2c temperature sensor communication routines, iar works very useful routine
