  This demo is based on the GD32350R-EVAL-V1.0 board, it shows how to use the ADC to
convert analog signal to digital data. The inner channel 16(temperature sensor channel) 
and channel 17(VREF channel) are chosen as analog input pin.

  The ADC routine sequence conversion begins by software, and the inserted sequence works in
automatic conversion mode. Every software trigger will trigger ADC to convert all the 
channels .

  The converted result will be displayed on the HyperTerminal by USART.
