  I assume the spec 'little endian' msb means
   
  ((( 0x45 & 0x0f ) << 8 ) | 0xfc ) / 16 * ( 1240/2047 ) == > 58.001954079140205
   
  Help Help?

  VPSU = ADC / 16 * 1.24 / 2047
  = 18480 / 16 * 1.24 / 2047 = 0.6996 This value looks wrong.Measuring with multimeter I get 7.46v .. sbrick iphone app gives 7.43v Help? Am I doing something incorrectly ?
