1. Function description
    1. The ADC samples and converts the analog voltage of the internal temperature sensor and converts it into a temperature value
2. Use environment
    Software development environment: KEIL MDK-ARM V5.26.2.0
    Hardware environment: Developed based on the development board N32G43XRL-STB V1.0
3. Instructions for use
    System Configuration;
        1. Clock source:
            HSE=8M,PLL=108M,AHB=108M,APB1=27M,APB2=54M,ADC CLK=108M/16,ADC 1M CLK=HSE/8,DMA CLK=108M
        2. DMA:
            DMA_CH1 channel is configuered as circular mode, carries a half-word of ADC1 conversion result to the ADCConvertedValue variable
        3. ADC:
            ADC configuration: continuous conversion, software trigger, right-aligned 12-bit data, conversion channel 17 is the analog voltage data of the internal temperature sensor
        4. Port configuration:
            PA9 is selected as the TX pin of USART1
            PA10 is selected as the RX pin of USART1
        5. USART:
            USART1 configuration: 115200 baud rate, 8 data bits, 1 stop bit, no parity, no hardware flow control, transmit and receive enable
        6. Function function:
            TempValue = TempCal(ADCConvertedValue) function converts the temperature ADC raw format data to the format of the unit of degrees
    Instructions:
        1. Open the debug mode after compiling, and add the variables ADCConvertedValue and TempValue to the watch window to observe
        2. Connect the serial port tool to the PA9 pin, and open the serial port receiving tool
        3. Running at full speed, you can see that the value of the temperature variable is close to 25 degrees at room temperature, and the serial port tool displays the temperature value in the real-time chip
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
