@par Application Description
How to implement thread creation using CMSIS RTOS API.
This application creates two threads with the same priority, which execute in
a periodic cycle of 15 seconds.
In the first 5 seconds, the thread 1 toggles LED1 each 200 ms and the
thread 2 toggles LED3 each 500 ms
In the second 5 seconds, the thread 1 suspend itself and the thread 2
continue toggling LED3
In the last 5 seconds, the thread 2 resumes execution of thread 1 then
suspends itself, the thread 1 toggles the LED1 each 400 ms
@note Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds)
based on variable incremented in HAL time base ISR. This implies that if HAL_Delay() is called from
a peripheral ISR process, then the HAL time base interrupt must have higher priority (numerically lower)
than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
To change the HAL time base interrupt priority you have to use HAL_NVIC_SetPriority() function.
@note The application needs to ensure that the HAL time base is always set to 1 millisecond to have correct
HAL operation.
@note The FreeRTOS heap size configTOTAL_HEAP_SIZE defined in FreeRTOSConfig.h is set according to the OS resources memory requirements of the application with +10% margin and rounded to the upper Kbyte boundary.
For more details about FreeRTOS implementation on STM32Cube, please refer to UM1722 "Developing Applications
on STM32Cube with RTOS".
@note The connection of the LCD reset pin to a dedicated GPIO PH7 instead of the STM32F469 NRST pin may cause residual display on LCD with applications/examples that do not require display.
The LCD clear can be ensured by hardware through the boards power off/power on or by software calling the BSP_LCD_Reset() function.
