  This demo is based on the GD32E517Z-EVAL-V1.0 board, it shows how to use ADC0 and
ADC1 regular follow-up mode convert function. PC2 and PC3 are configured as AIN mode.
PC3 pin is connected to the external voltage input. PC2 is the output voltage of the 
slide rheostat VR1 on board.

  TIMER1_CH1 is the trigger source of ADC0. When the rising edge of TIMER1_CH1 coming,
ADC1 starts immediately and ADC0 starts after a delay of several ADC clock cycles. The
values of ADC0 and ADC1 are transmitted to array adc_value[] by DMA. We can watch array
adc_value[] in debug mode or COM0.
  JP13 jump to USART0.
