1. Function description
    1. The ADC regular channel samples the analog voltage of the PA4 and PA5 pins, and the injection channel samples the analog voltage of the PA0 and PA1 pins.
    2. The regular conversion result is read into the variable ADC_RegularConvertedValueTab[64] array through the DMA_CH1 channel
           The result of the injection conversion is read into the variable ADC_InjectedConvertedValueTab[32] array through the conversion end interrupt

        2. The regular channel data sampling can be triggered by the rising edge of PA9, and the data sampling of the injected channel can be triggered by the rising edge of PA10.

4. Matters needing 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
