| // Simple test of BMP085 output using default settings. |
| // This example requires AUTO_UPDATE_TEMPERATURE to be true in bmp085.h otherwise temperature will not update. |
| // IMPORTANT!! To get correct values you MUST CHANGE init() parameters, in |
| // this example I've set 250m based on GPS data for my location. |
