chris stevens / Mbed 2 deprecated CCRMonitor12_sp07_120ver

A code to drive a 3sensor reading unit for monitoring the operation opf a closed circuit rebreather (CCR) with 3 electrogalvanic sensors. Also uses a DS1307 for realtime clock and an MPX5700 to read the depth (mounted inside the breathing loop to keep it 'dry'). circuit diagrams available on rebreather world.

Dependencies:   DS1307 TextOLED mbed
