UCD3138 LLCHBFirmware-1.2 ADC scale design

Hello,

These scale are defined in line 230 and 234 in system_define.h:

#define ADC12_IOUT_SCALER_MANTISSA (29947)

#define ADC12_VIN_SCALER_MANTISSA (32380)

Here is how these value comes from:

Iout scale = 1mohm*35.7kohm/1kohm = 0.001*35.7/1

29947 = ((Iout scale/2.5) << 12) << 9

Vin scale = 1.93/400

32380 = ((Vin scale/2.5) << 12) << 12

To change the scale, change the value defined in line 230 and 234.
