Detailed Description

Read nRF51822 VDD volatage and return 0 to 100% charging level. 

 #include "mbed.h"
 #include "nRF51_Vdd.h"

 nRF51_Vdd vdd(3.6f, 1.8f);
 // or follows if you don't use ADC function (more low current)
 // nRF51_Vdd vdd(3.6f, 1.8f, ONLY4VDD);

 int main() {
 uint8_t batteryLevel;
 float batt;

   while(true){
      wait(1.0);
      batteryLevel = vdd.read();
      batt = vdd.read_real_value();
   }
