stm32_button_routines

Routines for handling buttons done the right way :)

If you ever struggled with handling buttons in your MCU project - struggle no more. Here is a good example of button routines for STM32 microcontrollers coded with HAL in CubeIDE.

No interrupt nor lame 20ms delay "debounce".

The code includes non-blocking routines for following button events:

• pressing button
• pressing and releasing button

Use as many buttons as you wish, as long as you have enough GPIO_Inputs in your MCU!

Schematic for connecting button (and LED)

If you're short on space on PCB, you can use internall pull-up for button and ommit external resistors.

To do:

• long / short press detection
• multiple pressing detection
