                                样例使用说明
                                Sample Description
================================================================================
功能描述：
此样例演示了ADC的模拟看门狗监控通道6(PA0)的功能，当电压值超过上下限时，会进入看门狗中断，在中断中打开LED。

Function descriptions:
This example demonstrates the function of the ADC's analog watchdog monitoring channel 6 (PA0). When the 
voltage value exceeds the upper or lower limit, it will enter the watchdog interrupt, and in the interrupt, the LED 
will be turned on.

测试环境：
测试用板：MS32C001B_STK
MDK版本： 5.41
IAR版本： 9.20
GCC 版本：GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
Test board: MS32C001B_STK
MDK Version: 5.41
IAR Version: 9.20
GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10
================================================================================
使用步骤：
1. 编译并下载程序
2. 通道6(PA0)的电压值小于1.65V，LED灯不被点亮；
3. 通道6(PA0)的电压值大于1.65V，LED灯被点亮。

Example execution steps:
1. Compile and download the program and run it
2. the voltage value of channel 6 (PA0) is lower than 1.65V, the LED off
3. the voltage value of channel 6 (PA0) is higher than 1.65V, the LED on
================================================================================
注意事项：
1.通过USB转TTL模块连接PC与STK板,STK板与USB转TTL模块的连线方式如下；
@PrintfConfigStart
STK板         USB转TTL模块
PB4(TX)  -->  RX
PB5(RX)  -->  TX
GND      -->  GND
UART配置为波特率115200，数据位8，停止位1，校验位None
@PrintfConfigEnd

Notes:
1.Connect the PC to the STK board through the USB to TTL module, and the connection
method between the STK board and the USB to TTL module is as follows:
@PrintfConfigStart
STK board USB to TTL module
PB4(TX)  -->  RX
PB5(RX)  -->  TX
GND      -->  GND
UART is configured as BaudRate 115200, data bit 8, stop bit 1, and parity None.
@PrintfConfigEnd
