clemente di caprio / MPL3115A2

Llibrary for the WiGo MPL3115A2, I2C Precision Altimeter sensor.

Dependents:   KL25Z_Batt_Test WIGO_MPL3115A2 Multi-Sensor SPACEmk2 ... more

30/05/2013 Added and tested the data acquisition using Interrupt. Added code for Altimeter trigger Interrupt but not yet tested.

Very basic library. Under development. Need to add in order: 1. IRQ configuration. 2. FIFO mode configuration.
