STM32F4 Discovery board - Keil 5 IDE with CubeMX: Tutorial 1 Blinking LED - Updated Oct 2017 

really? dudde?

Mohammed Algailani Thank u Mohammed

Ekky Hermestian IW Thanks!

Thanks Qamar Hussain, really like your name brother.

I don't see anything wrong with Hindi ppl accent.

nothing wrong with Hindi but my ears almost bleed, it's so cringy.

@@JoseRomero-wp4ij maybe you should be grateful for people spending their time to show us this stuff. If you can understand what they are saying and the content is accurate, what is the problem ? ? 😀

Hi Muhammed, I am not sure if I will continue with the ENC28J60 tutorials,, as it was interrupted by my exams last year and now I am very tight with time to continue with it. If I would, it is not gonna be anytime soon. Thanks

zer3vro89 Cheers

Hi Eon, Good to know that my tutorials are helping you out. Ok, basically GPIO means: General Purpose Input/Output. So, each pin on the STM32F4 board is referred to an a GPIO pin because you can set it to be input, output or others (e.g. I2C, SPI, Analog, etc...). The pins are grouped into few ports (e.g. Port A, Port B, Port C, etc...), for the STM32F4, each port consists of 16 pins. Thus, if you want to use any pin within that port, say Pin12 in Port D (also called PD12), then you need to enable that GPIO port clock first. And this where enabling GPIO came from. I hope this clarifies it more. Thanks

Thank you for explanation! I subbed :-)

It is part of the project includes. An easy way to navigate there is to right click one of the gpio functions and click on go to reference. It will open the header file for you.

good one

@@mutexembedded2206 Thank you! looking forward to it!

Hi, Could be a hardware issue

Hi, HAL correspond to library functions that themselves implement low level direct register operations, so if you look inside HAL_GPIO_TogglePin, you will see something like this: GPIOx->ODR ^= (1UL

Hi, Thanks for your suggestion, I agree will be an interesting one.

You are right, can use it with SysTick Interrupt count. But I did not want to get into detailed Cortex-M NVIC at this stage.

Are you using the same board or any different? This STM32 integration is not available with every series of STM32. Even in F1 series no such HAL libraries are available directly.

rOHIT PATIL Hi sir, I think the F429 uses different pins for LEDs.. I think it is PD10 and PD11. Give that a try

Hi You need to make some changes to the project setup especially the startup and target file

@@mutexembedded2206 ok so in code no need to change anything just that settings we should change

Hi, it could be just the clock and port settings. Make sure you put the right clock frequency when enabling trace to achieve synchronization.

Hi, You can use SW4STM32 IDE without CubeMX. Set-up a project manually and select StdLibrary instead of HAL.

Many thanks friend !!! I've been trying to do this for years.

Hi, Need to ensure you handle SysTick correctly, any typing error in callback, it will not work. make sure you type it fully correct: void SysTick_Handler(void)

@@mutexembedded2206 Thanks for your information !. Would you share me your e-mail I need to ask something to you? My email address is frknalty61@gmail.com

Hi, This is correct error, you need to replace the x with your port. For instance, GPIOD: __HAL_RCC_GPIOx_CLK_ENABLE(wrong) __HAL_RCC_GPIOD_CLK_ENABLE(correct)

MYaqoobEmbedded Thanks, that solves the compiling problem, but how come my LEDs just stay on without blinking?

@@chaowang2771 I have same issue and think I have narrowed it down to some missing files within the main.c file but cannot solve the problem any further? I did notice that I got 6 warnings when first compiling the code but MYaqoobEmbedded code showed only 1 warning for inital compiling! have you managed to solve this problem, and if you have, can you share the solution please? @MYaqoobEmbedded , can you help with this problem also please.

@@brianaherne7396 Hi Brian, I have the same issue. Were you able to fix it? My LEDs aren't blinking as well.

Rick JR Hi Rick, Sorry, not sure if i got ur question.

Hello Rick, This is the main HAL header which gets installed as the STM32F4xx_DFP(Device Firmware Package) while installing Keil. It contains GPIO struct definitions. It is located at: C:\Keil_v5\ARM\PACK\Keil\STM32F4xx_DFP\2.12.0\Drivers\STM32F4xx_HAL_Driver\Inc\stm32f4xx_hal_gpio.h I hope this answers your question. Read this for more details: www.disca.upv.es/aperles/arm_cortex_m3/llibre/st/STM32F439xx_User_Manual/stm32f4xx__hal__gpio_8h.html

type #include "stm32f4xx_hal_gpio.h" then right click and chose: open document "stm32f4xx_hal_gpio.h"

I recommend CubeMX IDE also available from ST, free and simple to use. Just be sure to "build" the code so you can right click and find definitions.

Hi Could be your SysTick interrupt not handled. Check that you have a handler in the stm32f4xx_it.c

@@mutexembedded2206 Hi. It seems that I missed the 8:54 step. It works now. Thanks for your response

I often program in C/C++. Use C# for PC interface purposes. Want to use Python for PC interface? or as an IDE?

@@mutexembedded2206 I wanted to code all the in the IDE using Python.

@@mutexembedded2206 examples and run it in Python.

Jany Basha Hi Jany, Same principle.. Which board are using specifically?

MYaqoobEmbedded STM32f103C8t6

Jany Basha LED is on PC13

Hi, I have a basic FreeRTOS video demonstrated on the Nucleo board. Concept is the same. I am still planning on making tutorial series for FreeRTOS with STM32.

@@mutexembedded2206 thanks bro

You don’t have tutorial in Arabic?

Hi Easiest way is to open associated .c file and right click on any function inside and select Go to declaration... It will open .h file

I have already done that But it doesn't show like in your header file But I resolved my issue By going on to Stm and readed a document and I am following your lecture they are really good thanks for your reply :) jazak allah khair

Hi, 16 pins per port for STM32. Number of ports depends on the MCU Package/number of pins. You will find all these information in you specific MCU's datasheet.

@@mutexembedded2206 Hi Sir, can you please guide me how to configure Keil5 with Proteus

you can do it with cube ide

@@parisazaheri7775 thanks a lot

Hi mate, What's the problem, might worth mentioning it here, just so that if somebody else had the same, can read the comments.
