  This demo is based on the GD32H75EY-EVAL-V1.0 board, it shows how to 
use the ADC to convert analog signal to digital data.The ADC is configured 
in dependent mode, channel17(VBAT/4 channel), inner channel18(temperature sensor channel),
channel19(VREFINT channel) and inner channel20(high precision temperature sensor channel),
are chosen as analog input pin.

  As the AD convertion begins by software,the converted data in the ADC_IDTRx register
,where the x is 0 to 3.

  We can watch temperature, vref_value and vbat_value in debug mode or by COM.

  This example requires printing floating-point data. Please configure the
"Settings->GD ARM MCU Linker->Miscellaneous" option in the Embedded 
Builder project and check "Use float with nano printf" to enable this functionality.
