@par Example Description
|
|
|
|
|
|
|
|
|
|
How to configure the EXTI and use GPIOs to toggle the user LEDs
|
|
|
|
|
available on the board when a user button is pressed. It is based on the
|
|
|
|
|
STM32F0xx LL API. The peripheral initialization uses LL unitary service
|
|
|
|
|
functions for optimization purposes (performance and size).
|
|
|
|
|
|
|
|
|
|
In this example, one EXTI line (EXTI_Line4_15) is configured to generate
|
|
|
|
|
an interrupt on each falling edge.
|
|
|
|
|
|
|
|
|
|
In the interrupt routine a led connected to a specific GPIO pin is toggled.
|
|
|
|
|
|
|
|
|
|
In this example:
|
|
|
|
|
- EXTI_Line4_15 is connected to PC.13 pin
|
|
|
|
|
- when falling edge is detected on EXTI_Line4_15 by pressing User push-button, LED2 toggles
|
|
|
|
|
|
|
|
|
|
On STM32F072RB-Nucleo RevC:
|
|
|
|
|
- EXTI_Line4_15 is connected to User push-button
|
|
|
|
|

@par Hardware and Software environment
|
|
|
|
|
|
|
|
|
|
- This example runs on STM32F072xB devices.
|
|
|
|
|
|
|
|
|
|
- This example has been tested with STM32F072RB-Nucleo RevC board and can be
|
|
|
|
|
easily tailored to any other supported device and development board.
