Develop your application

At this stage, your system is ready and you can start developing your application code.

a)

The HAL provides intuitive and ready to use APIs to configure the peripheral, and

support polling, IT and DMA programming model, to accommodate any

application requirements. For more details on how to use each peripheral, refer to

the extensive set of examples provided.

b)

If your application has some real time constraints, you can find a large set of

examples showing how to use FreeRTOS and its integration with all middleware

stacks provided within STM32CubeF3. This can be a good starting point for your

development.

Caution:

In the default HAL implementation, SysTick timer is the source of time base. It is used to

generate interrupts at regular time intervals. Take care if HAL_Delay() is called from the

peripheral ISR process. The SysTick interrupt must have higher priority (numerically lower)

than the peripheral interrupt. Otherwise, the caller ISR process is blocked. Functions

affecting the time base configurations are declared as __weak to make the override

possible in case of other implementations in user file (using a general purpose timer for

example or other time source). For more details please refer to HAL_TimeBase example.
