However each example also puts more focus on a particular feature of the STM32 general-purpose-timer peripherals. For all the details on the general-purpose timers, refer to the “General-purpose timer cookbook”, application note (AN4776)...
* @note In the default implementation, SysTick timer is the source of time base. * It is used to generate interrupts at regular time intervals. * Care must be taken if HAL_Delay() is called from a peripheral ISR process, * The SysTick interrupt must have higher priority (numerically...
