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
    当系统采用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. Function description
    1. ADC1 regularly samples PA1, automatically injects and samples the analog voltage of the PB1 pin, and triggers sampling under the GTIM1 CC4 event
    2. The regular conversion result is read into the variable ADC_RegularConvertedValueTab[32] array through the DMA1_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 V5.34
        IAR EWARM 8.50.1

    Hardware development environment:
        Developed based on the full-function board N32H497ZGL7_EVB V1.0
        
3. Instructions for use
    System Configuration; 
        1. Clock source: HSI+PLL
        2. System Clock frequency: 
           SystemClock：240MHz
        3. Interrupt:
            ADC1 injects the conversion result to complete the interrupt open, steals 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
        4. Port configuration:
            PA1 is selected as the analog function
            PB1 is selected as the analog function
            PC6 is selected as general IO output
            PA3 is selected as TIM1 CH4 PWM output
        5. DMA:
            DMA1_CH1 channel loopback mode transfers ADC1 conversion result of 32 half words to ADC_RegularConvertedValueTab[32] array
        6. ADC:
            ADC1 independent working mode, GTIM1 CC4 trigger, 12-bit data right-aligned, regular conversion channel PA1, automatic injection of analog voltage data of conversion channel PB1.
        7. GTIM1:
            GTIM1 turns on CH4 output, CH4 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 PA1 and PB1 pins, the rules and injection channels are converted once every CC4 event occurs,
           and the variables are stored in the corresponding arrays. At the same time, you can see the PWM waveforms of GTIM1 CH4 in PA3
4. Attention
    When the system uses HSE clock (generally HSI is also turned on), RCC_ConfigAdc1mClk (RCC_ADC1MCLK_SRC_HSE, RCC_ADC1MCLK_DIV8) can be configured as HSE or HSI
    When the system uses HSI clock (generally HSE is turned off), RCC_ConfigAdc1mClk (RCC_ADC1MCLK_SRC_HSI, RCC_ADC1MCLK_DIV8) can only be configured as HSI
