  @Description
    This demo is based on the AT-START-F403A board.
	In this demo, You can #define pluse_cnt xx as the number of ADC conversion you want In at32f403a_407_board.h.
	Put the analog input signals to PC.02, PC.03 and PC.04 (ADC Channel12, ADC Channel13 and  ADC Channel14).
	
	ADC1 &ADC2 work at ordinary simultaneous mode triggered by TMR2CH2 
	while ADC3 works at independent mode triggered by TMR2CH3,
	Tmr2 works at subordinate hang mode which controlled by TMR1CH1.
	The results of ADC conversion are transferred by DMA.
	PC will printf the ADC conversion information Using USART1(PA9), and LEDs toggle after each printf.
    
	PC.02(Channel12)	----  	ADC3 Input
	PC.03(Channel13)	---- 	ADC2 Input
	PC.04(Channel14)	---- 	ADC1 Input
	PA9 (USART1)		----	PC 
	Ground				----	Ground
   
for more detailed information. please refer to the sample code document SC0001.
