21 / 29 page ![]() Getting started with STM32CubeF3 UM1766 21/29 DocID026352 Rev 8 7. 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. |
