STM32F7 Discovery board - SW4STM32 Eclipse with CubeMX: Tutorial 29 - LCD & Touch

[@slmmoese]

This is a really good tutorial. Thanks. There are a few issues I have, if anyone cares to comment: (1) There are a lot of errors that pop up in stm32746g_discover_ldc.c. Hundreds of undefined variables. I have no idea how the program compiles, but it does. (2) Nothing is done with the UART. It isn't initialized, etc. Though it all works and gives a good intro and framework for the LCD, graphics, and touchscreen, it *might* be better to go through the "Cube" builder to create all of this. Just my 2 cents as I'm getting started here.... But good tutorial. Thanks.

Hi, Starting with CubeMX is possible with a certain version of CubeMX.

[@JoshHin13]

Hi I tried use LCD screen on my stm32f7 following this tutorial but it doesnt work at all. At the beginning i use Cube IDE instead of cube MX and S4W. You build end up without any warning, but i have some warnings - Description Resource Path Location Type "__HAL_LTDC_RELOAD_CONFIG" redefined stm32f7xx_hal_ltdc.h /LCD/Drivers/STM32F7xx_HAL_Driver/Inc line 408 C/C++ Problem I have definition this macro in two different files. One definition is in file from your github and one in stm32_hal_legacy.h So it doesnt work and the program stops at infinity loop. Could you help me to fix it ?

[@ESEben10]

Is it possible to print images stored on the board memory onto this kind of LCD?

[@micklr143]

I have an error when I build the project : cannot open linker script file ../: No such file or directory collect2.exe: error: ld returned 1 exit status

[@ShizzleMyChizzle]

Dang, just realised that if you regenerate the cubemx code, all the h files you manually added gets removed and has to be added again, that's only bummer.

Very good video to get started with STM32F746NG Discovery board :)

[@daringeagle5745]

I have discovery board with lcd and capacity touch panel. But that has 769 not 746 cpu. I saw some of the header files you used are specific to 746. What do you suggest that how can I follow this tutorial with 769? What files I would need to change from the files you provided here? And from where I can get the 769 specific files?

[@manusv799]

Hi, I'm using stm32f746d disco, I wanted to monitor the sensor data and display it in lcd. Can you give any suggestion links

[@africafuture8158]

Hi sir i worked with STM32f769 but when ia wanna build project i get an error in fonts.c files and the functin who i copie in file .text can you help me plaise

[@earlycastle411]

Hello. I'm the very newbie on this. Though it could be very silly question, did you coded this files(5:25) that you've linked just under the video by your self? Or st.com serves the files like that? Since, I'm studying STM32F469I-DISCO, not STMF7 Series, so that I think I can't follow your lecture anymore. What do you think I can do now? Thanks for reading.

[@mutexembedded2206]

Hello, A bit of both. I modified ST files. In your case, i would suggest you read ST F4 firmware package and look for your board. It can be hard to read but for long term, you will get there. I wish I could make it shorter by making a video, but I very busy nowadays with work. But let me know if you got stuck, I will do my best to reply.

[@earlycastle411]

@@mutexembedded2206 I thank for your kindness. I'll try.

[@aymen_dh2499]

Great! I have a suggestion. How about a demo of audio signal on STM32F7. Thx Mohammed.

Thanks Bro! How can i flash original firmware of the stm32f746 discovery board?

[@sayalijoshi5010]

Hello. Is this tft compatible with stm32f407vg? I want to make gui with icons as buttons and all. Can u help me how do I do it?

[@mutexembedded2206]

This type is not compatible with the mentioned F4. You can use 8080 interface LCD

[@francisgremillet7546]

Great tuto ! Just a mistake : STM32F746-Disco Led is on Pin I 1

[@nasrinmoni8908]

Hello. I did the following tutorial with Keil 5 and I didn't have any error and the project compiled. but I got a white LCD. What should I do? Where is the problem?

[@mutexembedded2206]

You have missed some code somewhere.

[@nasrinmoni8908]

@@mutexembedded2206 Is it any difference between using Keil 5 or any other compiler?? Cause I did the same as you explained but I employed another compiler.

[@mutexembedded2206]

@@nasrinmoni8908 No difference in final result. If you use it correctly

[@D1e9o-SIIA]

Hi MYaqoobEmbedded, I wanted to ask you if it was possible for you to develop a communication tutorial MCU series to MCU in RS485 protocol using SN75176 or MAX485 for example between Discovery Stm32f407 and Nucleo-64 or as it is more comfortable for you !🤷‍♂️. ah!🤔 And if it's not too much to ask in Keil 😂. thank you very much !!!👍🏻, regards.🙋‍♂️

Hi Ali, it is on my list for coming tutorials. Thanks

[@stevenchavarro3644]

Thank you for your tutorials, By the way, how long did it take you to master everything related to these embedded systems?

[@mutexembedded2206]

Hi, About 4 years :)

[@DAMIRSALAKHOV]

Hi, How to save changes after regeneration? To repeat 10 times a day the same operation is not comfortable. Thanks.

[@bears7777777]

you have to place your code within the comments that say /* USER CODE BEGIN */ and /* USER CODE END */ any code that is not within those comments will be removed. also variables and such have places labeled for that

[@bears7777777]

Also, I believe there is a setting in CubeMX that changes whether unused files are deleted or not. If you create or add your own files you may need to uncheck it so they don't get *deleted*. There might even be an option to completely wipe the files every time too so check for that

[@mutexembedded2206]

@@balkischaabi1226 Ok sure, I recommend you start from the video here, you will be able to display bmp images with this library here. Then, do the Bluetooth bit to receive the image, easiest way is to store it in SD Card, then display it from there. You will get there if you tried. Unfortunately, I Don't have much time this period to set a full series on programming LCDs

[@marioc3810]

Hi thanks so much for all your videos they are great, i have bought a bunch a development boards like nucleo and discovery among others because i really like this topic, just i want to know how can i learn embedded MCU programming, i follow your steps and i feel i'm not doing something far from copy and paste you know, so my question is, where do you get the information about the programming part for MCU ? i have the datasheet, user Manuals, everything that ST provides but programming is like dark magic, i would really appreciate some enlightenment on this. Thank so much.

[@mutexembedded2206]

Hi Mario, I did the same tutorials within 2 months in my training 4 years ago, but was not that useful.. It's the work I did after that of programming on STM MCUs for 3 years that got me here.

[@David-nk7pv]

@@mutexembedded2206 Hello, I feel like Mario... what kind of work did you do in those 3 years? I'm trying to learn to be able to figure out by myself things like what you did in this video, but reading books and watching tutorials is not helping much. Perhaps a video explaining how you learned would be the most useful of all

[@daringeagle5745]

In my humble opinion you can start from learning C or micro C. There are many tutorials available online. Most of them are free.
