1、功能说明
    1、ADC1开启增益补偿与偏移补偿的条件下进行采样、转换PB1引脚的模拟电压
    2、其中ADC1转换结果通过DMA1_CH1通道读取到变量ADCConvertedValue
2、使用环境

    软件开发环境：
        KEIL MDK-ARM V5.34
        IAR EWARM 8.50.1

    硬件开发环境：
        基于全功能板N32H497ZGL7_EVB V1.0开发
        
3、使用说明
    系统配置；
        1、时钟源： HSI+PLL
        2、系统时钟频率：
           SystemClock：240MHz
        3、端口配置：
            PB1选择为模拟功能
        4、DMA：
            DMA1_CH1通道回环模式搬运一个半字的ADC1转换结果到ADCConvertedValue变量
        5、ADC：
        ADC1独立工作模式、连续转换、单通道模式、软件触发、12位数据右对齐，转换结果即PB1的模拟电压数据 ,增益补偿系数为2*4096 ,正向偏移 0x400,饱和使能.
    使用方法：
        1、编译后打开调试模式，将变量ADCConvertedValue添加到watch窗口观察
        2、通过改变PB1引脚的电压Voltage，可以看到转换结果变量同步改变，数据寄存器的结果Result = Voltage * 2 * 4095/3.3 + 0x400. 
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_HSI, 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 performs sampling with gain compensation and offset compensation enabled ,converts the analog voltage of the PB1 pin
    2. The ADC1 conversion result is read to the variable ADCConvertedValue through the DMA1_CH1 channel
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. Port configuration:
            PB1 selected as analog function
        4. DMA:
            DMA1_CH1 channel loopback mode transfers a halfword of ADC1 conversion result to ADCConvertedValue variable
        5. ADC:
            ADC1 independent working mode, continuous conversion, single-channel mode, software trigger, 12-bit data is right-aligned,
            conversion result is the analog voltage data of PB1, Gain compensation factor is 2*4096, positive offset 0x400,enable saturation .
    Instructions:
        1. After compiling, open the debug mode and add the variable ADCConvertedValue to the watch window to observe
        2. By changing the voltage (Voltage) of the PB1 pin, you can see that the conversion result variable changes synchronously . the data register result = Voltage * 2 * 4095/3.3 + 0x400.
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
