Tutorial CubeMX 4 External Interrupts EXTI

Working with external interrupts in a project generated by STM32Cube is shown. Dealing with bouncing contacts by waiting before taking action is demonstrated. Passing variables from the stm32f4xx_it.c module to main.c module is also shown.
Once again Cube let the programmer concentrate more on the C part and less on initializations. However, the understanding of the hardware principles of the interrupts is highly recommendable.

I learned how to use a variable inside an interrupt. Thanks!

hi, do you have a example the usb-host?

[redsddd]

YEAH AWESOME delay with main function congratulion!

Hi Sever, How we can define polarity? Is the interrupt activated on both falling and rising edge?

[hyperloop]

Sever, if you select the board from MCU selector section then you do not need to click "clear pinout" .

Where the value of delta_t is Increasing?

what is difference between in pre-emption priority and subpriority??
I wanted to make the priority of External interrupt higher than USART1 interrupt.How to do it?

Hey sever. I really liked your video. all your videos are great. I tried interrupts with led. Can you help me in generating a pwm signal using an external interrupt activated using a button?

[slap_my_hand]

For some reason the debouncing doesn't work for me. There is no delay, even if i set thefor loop to have a delay of 1 second.

how can an int variable get till 1, 000, 000?? Isnt the limit 65535? I tried with uint_32 but it didnt work lol
