4、注意事项
    当系统采用HSE时钟时（一般HSI也是打开的），RCC_ConfigAdc1mClk(RCC_ADC1MCLK_SRC_HSE, RCC_ADC1MCLK_DIV8)可以配置为HSE或者HSI
    当系统采样HSI时钟时（一般HSE是关闭的），RCC_ConfigAdc1mClk(RCC_ADC1MCLK_SRC_HSI, RCC_ADC1MCLK_DIV8)只能配置为HSI

    1. The ADC regular channel sampling PC2, automatically inject and sample the analog voltage of PC3 pin, and trigge source is TIM1 CC2 event
    2. The regular conversion result is read into the variable ADC_RegularConvertedValueTab[32] array through the DMA_CH1 channel
        The injected conversion result is read into the variable ADC_InjectedConvertedValueTab[32] array through the conversion end interrupt
2. Use environment
    Software development environment: KEIL MDK-ARM V5.26.2.0
    Hardware environment: Developed based on the development board N32L40XML-STB V1.0
3. Instructions for use
    System Configuration;
        1. Clock source:
            HSE=8M,PLL=64M,AHB=64M,APB1=16M,APB2=32M,ADC CLK=64M/16,ADC 1M CLK=HSE/8,DMA CLK=64M,TIM1 CLK=64M
        2. Interrupt:
            ADC injection conversion complete interrupt enable, steal priority 0, sub-priority 0
            In the interrupt function, the injection result is read into the ADC_InjectedConvertedValueTab[32] array, and the PC6 level is flipped
        3. Port configuration:
            PC2 is selected as the analog function, ADC1 conversion channel
            PC3 is selected as the analog function, ADC1 conversion channel
            PC6 is selected as general IO output
            PA8 is selected as TIM1 CH1 PWM output
            PA11 is selected as TIM1 CH4 PWM output
        4. DMA:
            DMA_CH1 channel is configuered as circular mode, carries 32 half-word of ADC1 conversion result to the ADC_RegularConvertedValueTab[32] array
        5. ADC:
            ADC TIM1 CC2 trigger, 12-bit data right-aligned, regular conversion channel PC2, automatic injection of analog voltage data of conversion channel PC3
        6. TIM:
            TIM1 turns on CH1 CH4 output, CH2 is used to trigger ADC conversion
    Instructions:
        1. Open the debug mode after compiling, and add the variables ADC_RegularConvertedValueTab[32], ADC_InjectedConvertedValueTab[32] to the watch window for observation
        2. By changing the voltage of the PC2 and PC3 pins, the rules and injection channels are converted once every CC2 event occurs, and the variables are stored in the corresponding arrays. At the same time, you can see the PWM waveforms of TIM1 CH1 and CH4 in PA8 PA11
4. Attention
    When the system uses the HSE clock (HSI is generally enabled), ), RCC_ConfigAdc1mClk (RCC_ADC1MCLK_SRC_HSE, RCC_ADC1MCLK_DIV8) can be configured as HSE or HSI
    When the system uses the HSI clock(HSE is generally disabled), RCC_ConfigAdc1mClk(RCC_ADC1MCLK_SRC_HSI, RCC_ADC1MCLK_DIV8) can only be configured as HSI
