-/** BMP180 class.
- *  Read Pressure and temperature from the BMP180 Breakout I2C sensor
- *
- * Example:
- * @code
- * #include "mbed.h"
- * #include "BMP180.h"
- * 
- * #if defined(TARGET_LPC1768)
- *     #define PIN_SDA p9
- *     #define PIN_SCL p10
- * #elif defined(TARGET_KL25Z) // watch out for the PTE0/PTE1 mixed up in the KL25Z doc 
- *     #define PIN_SDA PTE0
- *     #define PIN_SCL PTE1
- * #endif
- * 
- * int main() 
- * {    
- *     BMP180 bmp180(PIN_SDA, PIN_SCL);
- *     float pressure, temperature;
- *     
- *     // bmp180.Initialize(); // no altitude compensation and normal oversampling 
- *     bmp180.Initialize(64, BMP180_OSS_ULTRA_LOW_POWER); // 64m altitude compensation and low power oversampling
- *     
- *     while(1) 
- *     {        
- *         if (bmp180.ReadData(&pressure, &temperature))
- *             printf("Pressure(hPa): %8.2f \t Temperature(C): %8.2f\n", pressure, temperature);  
- *         wait(1);
- *     }
