Bob Giesberts / Mbed 2 deprecated Inductive_Sensor_3

Version 3.0: Switching to newer LDC1614 which is placed on the same PCB.

Dependencies:   Bob DS1825 LDC1614 LDC1101 SDFileSystem mbed

Fork of Inductive_Sensor by Bob Giesberts

Revision:
5:736a81a59f3c
Parent:
4:ae441c5727b9
Child:
6:ff39d60061ca
Power management: take samples for INTERVAL_ON seconds, then go to deepsleep for INTERVAL_OFF seconds. ; There is still a very stupid error with the SDFileSystem. writing to SD does not work properly. After power is cut from SD, it can not be awoken..
