# A Intelligent house system Base on STM32F407 and FreeRTOS created by stm32cubemx
## >>Some bug record:
>2024/6/28
1.Programme was stuck in Hay_delay() ,because the control system of freertos is based on sysTick timer.
Solution: change sysTick base on TIM4 or don't use it or rewrite fuction
2.Programme die in prvTaskexiterror() , before call for xQueueGenericSend()
Solution: forget to create the queue of some Task queue handle
3.DTH11 init is failed,because of TIM7 is stuck in get count value function
Solution:change delay base on TIM4 ,and verify the ms/ns accuracy

>
> 1.use vTaskdelete to kill the void MQTT_Client_Init(void *Param),result in MQTT break connection
> Solution: substitute vTaskdelete() for vTaskSuspend();
> 2.osPriority setted by hal's freertos doen't match the original priority;
> Solution: substitute #include "cmsis_os.h" for #include "cmsis_os2.h",use the (osPriority_t) to relieve the limitation of priority is less.
> 3.Programme through three times start to stuck in vportfree(),consider maybe its stack and heap is overflow,so expand the capacity.but helpless.
> Solution: after check the process,I find myself create and delete task handle over and over again ,so change the method and add a judge to determine handle or not
> code :
> if (G_xMQTT_Client_Task != NULL)
> {
> vTaskDelete(G_xMQTT_Client_Task);
> G_xMQTT_Client_Task = NULL;
> printf("G_xMQTT_Client_Task task deleted\r\n");
> }

1.when create same priority tasks which are running immediately
Solution: use Mutex to protect resource avoid being interrupted
2.Programme was stuck in hardware_error,because of stack is overflow
Solution:use memset to clear upload buffer.

> 1.add lcd and use the spi+dma created by hal library , when send a data after the program will wait hal_ready never exit
>
> call for HAL_SPI_Abort()
