I started studying interrupts on stm32 specifically the stm32f4 discovery board. To do so close the Pin Configuration window and from the System column, click on the NVIC button. Each input line can be independently configured to select the type (interrupt or event) and the corresponding trigger event (rising, falling, or both). The only difference between an external interrupt and an internal. I don't think you want to use an analog signal to generate an interrupt. 3 Create project in STM32CubeMX ↑. Here's the code I have so far; main. External Interrupt using Registers. So the stm32 got stuck. Each GPIO pin can be individually configured by software in any of the following modes: • Input floating • Input pull-up • Input-pull-down • Analog • Output open-drain with pull-up or pull-down capability • Output push-pull with pull-up or pull-down. So, that one group is called GPIO port. Getting started with the STM32 HAL development environment. i found this example in which you have to press.
