bmp180_barometer1

代码说明：

  借由蓝牙芯片CSR1010（未用蓝牙）实现对气压计BMP180的驱动并显示到1602中，从而能对气压和温度有个环境上的了解。(With the help of bluetooth module CSR1010,of course where I did not ultilize bluetooth function,I achieved the goal of driving the barometer BMP180 besides displaying to LCD1602,thus having a well knowledge of the surroundings.)
