[Shanghai Hangxin ACM32F070 development board review] 7. Give the watchdog a thread [Copy link]

 

In my mind, threads are tasks and tasks are threads.

Last time I ran the RTX operating system in the watchdog routine, so this time I will create another task to bring the dog with me. After all, it was modified from the watchdog program, and it would be bad to change it away.

The first step is to change the parameters of the watchdog function

The previous program is void WDT_Reset_Test(void) and is changed to void WDT_Reset_Test(void const *argument)

If you don't change RTX in this way, it seems that it will not pass.

Step 2: Add an ID

osThreadId Dog;

Step 3: Create a task

Dog = osThreadCreate(osThread(WDT_Reset_Test), NULL);

The running results are as follows;

Full Program:

The parameters of the watchdog function are really modified like the original poster's.
