Sample Description

功能描述：
|
|
|
此样例演示了WWDG的 窗口看门狗功能，配置WWDG的窗口上限（下限固定是0x3F），程序中
|
|
|
通过delay延时函数，确保程序是在WWDG计数窗口内进行喂狗动作，通过LED灯闪烁，可以判
|
|
|
断窗口内喂狗并未产生复位。
|
|
|

Function descriptions:
|
|
|
This example demonstrates the window watchdog function of WWDG. Set the upper
|
|
|
limit of the window of WWDG (the lower limit is fixed at 0x3F).The program
|
|
|
ensures that the WWDG is refreshed in the WWDG counting window through the delay
|
|
|
function, and can judge that the WWDG is refreshed in the window without
|
|
|
resetting through the LED light blinking.

使用步骤：
|
|
|
1. 编译下载程序并运行；
|
|
|
2. 程序默认会在窗口时间内喂狗，程序不会复位，LED灯一致闪烁；
|
|
|
3. 注释掉宏定义”#WINDOW_IN",打开宏定义“WINDOW_UPPER”，重新编译下载并运行；
|
|
|
4. 程序会一直复位,LED灯循环点亮4s，熄灭500ms；
|
|
|
5. 注释掉宏定义”#WINDOW_UPPER",打开宏定义“WINDOW_LOWER”,重新编译下载并运行；
|
|
|
6. 程序会一直复位,LED灯循环点亮4s，熄灭500ms。
|
|
|
|
|
|
Example execution steps:
|
|
|
1. compile and download the program to MCU and run it.
|
|
|
2. By default, the program will refresh WWDG within the window time without
|
|
|
resetting, and the LED light will keep blinking;
|
|
|
3. Mask the macro definition "#WINDOW_IN",unblock the macro definition
|
|
|
" WINDOW_UPPER ", re-compile, download and run;
|
|
|
4. The program will always reset,LED light cycle on 4s, off 500ms;
|
|
|
5. Mask the macro definition "#WINDOW_UPPER", unblock the macro definition
|
|
|
" WINDOW_LOWER ", recompile, download and run;
|
|
|
6. The program will always reset,LED light cycle on 4s, off 500ms.
