功能描述：
|
|
|
此样例演示了ADC的模拟看门狗功能，当开启看门狗的通道的电压值不在设定的上下限中，
|
|
|
会进入看门狗中断。
|
|
|
|
|

Function descriptions:
|
|
|
This example demonstrates the analog watchdog function of ADC. When the voltage
|
|
|
value of the channel that opens the watchdog is not within the set upper or
|
|
|
lower limits,Will enter watchdog interrupt.

测试环境：
|
|
|
测试用板：PY32F403_STK
|
|
|
MDK版本： 5.28
|
|
|
IAR版本： 9.20
|
|
|
GCC版本：GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
|
|
|
Test board: PY32F403_STK
|
|
|
MDK Version: 5.28

使用步骤：
|
|
|
1. 编译下载程序到MCU，并运行；
|
|
|
2. PA4的电压值小于1.65V(供电电压为3.3V),不会进入看门狗中断，LED灯不亮；
|
|
|
3. PA4的电压值大于1.65V(供电电压为3.3V)，进入看门狗中断，LED亮。
|
|
|
|
|
|
Example execution steps:
|
|
|
1. Compile and download the program to MCU and run it;
|
|
|
2. If the voltage value of PA4 is less than 1.65V (with a power supply voltage of
|
|
|
3.3V), it will not enter the watchdog interrupt and the LED light will not light
|
|
|
up;
|
|
|
3. If the voltage value of PA4 is greater than 1.65V (with a supply voltage of
|
|
|
3.3V), the watchdog will interrupt and the LED will light up.

注意事项：
|
|
|
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；
|
|
|
STK板 USB转TTL模块
|
|
|
PA02(TX) --> RX
|
|
|
PA03(RX) --> TX
|
|
|
GND --> GND
|
|
|
|
|
|
Notes:
|
|
|
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:
|
|
|
|
|
|
STK board USB to TTL module
|
|
|
PA02(TX) --> RX
|
|
|
PA03(RX) --> TX
|
|
|
GND --> GND
