Tutorial STM32F746g Discovery LCD using Keil MDK RTX

[@powerproton9139]

Thanks. but i have problem. .\Objects\3.axf: Error: L6406E: No space in execution regions with .ANY selector matching guiconf.o(.bss). .\Objects\3.axf: Error: L6407E: Sections of aggregate size 0x100000 bytes could not fit into .ANY selector(s). minute 4:14

i edit GUI_NUMBYTES 0x10000, i build ok, but LCD is not display anything

[@SeverSpanulescu]

Free trial Keil has a 32k limit. You may try the pro for 7 days when you use the display, or use another variant.

@@SeverSpanulescu yes. i do. but. i try, i build ok, with minute 4:14. i programming ok. but lcd not display anything. i im looking for problem

@@SeverSpanulescu can you share project ?. thanks

@@powerproton9139 Sorry, it was 4 years ago... Where should I find it? I don't keep these, I am in atomic physics. And maybe the IDE changed a lot. If I succeeded, why couldn't you ? I'm in my 60's now :)

Hi, do you know how configure the library to use other LCD with STM32F7? If you have time I would like to ask you some questions about configure the code for other TFT, if you can answer, please send me a message.

Hi..Can you please do a tuorial how to interface usb mouse with stm..i want to read mouse movements and mouse buttons but dont know how to do it.

[@pavlychev_funny]

Can you give me source code, because my screen doesn’t show anything. Thanks

[@chloemcholoe3280]

Thanks for the video! But i really wish you talked more loudly and clearly.

[@vietha1510]

Hello,I followed your instructions but the dark screen does not show anything

[@SeverSpanulescu]

As I remember, the screen remains dark if you do not increase the stack as shown at 3:37 and limit the number of bytes reserved for GUI (10,000) as shown at 3:57. You must also comment the MPU_Config(); line. I'm sure you'll succeed. Good luck!

[@vietha1510]

thanks.

It's 2019! Why is everything still at such a low level programming? Why don't we have a friendly IDE and GUI for creating graphics and components? This stuff is stuck back in the 1980's, don't you think?!?!

[@SeverSpanulescu]

There are lots of high level IDE and GUI. One may choose: low level means performance and a big effort, while high level is the contrary. Some medium level languages (as C) are sometimes a good compromise. You don't need assembly language for an automatic aspersor, but you need it for automotive or rocket science. It's a matter of speed mostly. Of course, it's not the case here. This video is for educational purpose, as an exercise.

[@driversteve9345]

@@SeverSpanulescu Lots of high level IDE and GUI? I haven't been able to find them except for Nextion! Problem with them is that you are very limited with what you can do and it's not expandable. We got awesome frameworks for web development and desktop development but hardly anything for these displays. Maybe they aren't in demand?

[@SeverSpanulescu]

@@driversteve9345 I thought you were speaking generally, now I see what you mean. Well, I think these microcontrollers evolve hardware pretty quickly and rather diversified, so the software can't keep the peace. Anyway, if you compare with 1980... in that year I played with Z80 and I had only machine language for it: C3.21.B2...... and so on (!!!) . I think that software tools progressed too. By the way, if you find some friendly GUI for ARM, please let me know, I would be very interested. Thanks.

[@chloemcholoe3280]

Omg glad it’s not me. All the embeded programming resources SUCK. Like I’m mainly a PC programmer and on the Pc software programming side you have millions of amazing libraries and lots of feature rich IDEs meanwhile STM’s server are SLOW like hell. Their documentstions are so basic and ugly. Keil has near zero IDE features and it looks do ugly. Like god Embed stuff look like they’re from the 80’s. This is one of the reasons i keep embed as a hobby and stick to high level coding for my future

[@chloemcholoe3280]

I copy paste my code from Visual Studio code to keil when i wanna compile and upload it ;p

[@diegoleal9625]

Nice tutorial... unfortunately i have this message: Error #603: 'Segger.MDK-Plus::Graphics:CORE:5.36.6': component requires valid MDK-ARM Plus or MDK-ARM Professional license =/

[@SeverSpanulescu]

Hello! You should use the seven days trial license www2.keil.com/mdk5/activation.

[@duytranpham4782]

Hello, I did comment the MPU_Config(); line, but It didn't work...Can you help me figure it out? Thanks
