  This demo is based on the GD32G553Q-EVAL-V1.0 board, it shows how to use the ADC
differential input mode to sample the the difference voltage between two ADC channels.
The ADC is configured in continuous mode, PC0,PC1 are chosen as analog input pin.

  As the ADC conversion begins by software, the converted data from ADC_RDATA register
to SRAM begins continuously.

  The analog input pins should configured to AIN mode, and need connected to the different
voltages. We can watch array adc_value in debug mode or COM.
