xilinx fpga edk开发实例，用I2C总线控制温度传感器-xilinx fpga edk development examples, with the I2C bus control temperature sensor

This tutorial shows how to use an IIC controller with MicroBlaze. The IIC controller is connected to a Texas Instruments TMP100 temperature sensor. A custom application with code to communicate with the temperature sensor is used to exercise the

一般而言，Xilinx Microblaze会被用来在系统中做一些控制类和简单接口的辅助性工作，比如运行IIC、SPI、UART之类的低速接口驱动，对FPGA逻辑功能模块初始化配置及做些辅助计算等等。类程序的代码量普遍不大，常常在十几KB到几时KB之间，因此对存储的需求通常也不是太高，使用FPGA内部RAM资源便已经够用(Generally speaking, Xilinx Microblaze will be used to do some auxiliary work of control
