[DemoCode下载] NUC131在Arduino下读取EEPROM的方法

/*

                This sample code sets I2C bus clock to 100kHz. Then, accesses EEPROM 24LC64 with Byte Write

                and Byte Read operations, and check if the read data is equal to the programmed data.

        

                This example code is in the public domain.
