sandeep ponnuru / Mbed 2 deprecated DanTkr

An integrated code base for smart watch model using nrf51822. Used the efforts from Roger Clark, Goran Mahovlic, Nordic team SDKs and mbed repos on OLED. Programming: The watch prototype can be interfaced to Tiny Seeed BLE programmer (left of the Tiny Seeed BLE board). Connect SWDIO, SWD CLK, Vin and GND pins. For USB debugging also connect RX and TX pins. Used Roger's nice webpage to come up with the pin mapping and many other HW insights. http://www.rogerclark.net/arduino-on-the-id100hr-fitness-tracker/

Dependencies:   BLE_API SFE_MicroOLED_debugPrint mbed nRF51822
