Edison平台eclipse环境下通过MRAA库使用IIC、SPI、UART例程（BMI160、MS8607）

MRAA库IIC例程：

以下程序是操作MS8607传感器

mraa_init();
/* initialize I2C on bus 0 */
m_i2c = mraa_i2c_init(1);
mraa_i2c_frequency(m_i2c,MRAA_I2C_FAST);//400K
/* now run in a loop 10 times, reading the seconds */
/* register and printing it.*/
mraa_i2c_address(m_i2c, 0x76);
//mraa_i2c_address(m_i2c, 0x0f);
mraa_i2c_write_byte(m_i2c, 0x1e);
while(1)//iic1
{
char buf = 0;
char cdata = 0x00;
char buff[2];
