Adding an interrupt to an existing program
Hi Pascal,
I managed to merge both examples : GPIO_EXTI and TIM_TimeBase on a STM32F469I-DISCO board.
The TIM3 can be used from the GPIO_EXTI project by updating the list of modules to be used in the HAL driver.
It is done in the stm32f4xx_hal_conf.g file : define HAL_TIM_MODULE_ENABLED
