******************************************************************
Generate the code using STM32CubeMx for Keil. In this tutorial, we will learn how to generate Nucleo board initialization c code for Keil uvision using the STM32CubeMx. STM32F401RE Nucleo board have 64pin ARM Cortex M4 + FPU on board running on 84MHz maximum speed. PIN 5 of GPIOA is connected with user LED and PIN 13 of GPIOC is connected with Push Button. The external interrupt is also available to each GPIO pins. The push button is initialized into the external interrupt mode.
The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features. The Arduino™ connectivity support and ST Morpho headers make it easy to expand the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger and programmer. The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together with various packaged software examples, as well as direct access to mbed online resources.

How did you get , if(tDelay == 250) is 500ms, can you please explain. Thanks
Hi, Thanks for this good explanation.
Could you please inform reason about enabling of RCC and CRS global interrupt.
Can you make video on can protocol
Hey do you know how to program a capacitive touch that when it touched it turns on the LED?
hey man, this is awesome, thanks bruv
Hi, how can I got the list of functions on IAR ? I don't find it...
hi even after enabling the interrupt checklist and then generating the code, void EXTI..(void) function is not creating. any suggestions please?
Your video is awesome! Thanks for doing this
Thank you. I really appreciate for this tutorial. :D
This code works, thankyou. Where can I find example #3?
Please watch lesson 3 here ruclips.net/video/kI_Xngn3G8c/видео.html
does rcc necessary and ? which external crystal clock (on the board ) are you referring for rcc then ?
thank you ...
I was actually looking for this but the logic of 2000 and 500 ms is still very unclear to me. Explain that. Thanks again
Kindly, revisit ISR once again and you will notice there that at every interrupt I am changing delay value i.e. If current tDelay is 1000 then I am assigning it to 250 and so on. This logic shows that interrupt is working if tDelay is changing after pressing button. I hope it helped you. Thanks for watching.
How did you know that to switch the button for interrupt GPIO to PC13 with external interrupt? Is that in the documentation of the board?
Yes.
:) super!

I am New in Arm develpment And Bought Nucleo 64 STM32F446RE, I wanna Know whether this video is exactly worakble for my board too
Yes, it will work with a very little change. I am sure you would be able to make it without any difficulty.
Where is the code?
Do we need full version of keil for programming
Hi,
You don't need if your code size is under 32KB which Keil provide in free version.
@@LaxmiKantTiwarilaxmimerit ok tq could blz make a video ok can protocol .I have down can coding for Stm32f103C8 and Stm32f446re but don't know we're I am facing the problem
Gudelli Thrishool I will try my best in near future. thank you for watching my videos. Please share it on social media if you have found it helpful to you. Thank you.
Excellent tutorial
Which denouncing do you speak about!!!!!!!!!! There’s a capacitor to eliminate the denouncing when you push the button, so you don’t need to add a delay to complicate the instruction!
It is necessary otherwise capacitor discharge too fast
Don’t worry ST don’t use one cap, it uses 2 even 3 cap and a large resistor ;)!
Try without the delay and it works fine as we expected
Hi,
There is just one capacitor is connected with user button which is 100nF and resistance connected with it is 4.7K therefore RC is equal to 4.7k x 100nF which really very small amount of time. You might have got correct answer but I am not sure you will always get. Please refer datasheet for schematic Diagrams.
I have 3 connected cap on my board! Even thought with one cap it works fine, but I’m not sure that you have only one cap or one resistor, there’s an other resistor on your board, I advice you don’t use denouncing via software bc the uC will be occupied and waiting out the delay
Merci.
For those who don't know French. 'Merci' means Thank You :P
