STM32 + LCD Display (FMC) Firmware Tutorial - Phil's Lab

[@ATwice291]

watched the video and remembered my first days at work. STM32F7 + QSPI Flash + FMC SRDAM + LTDC RGB888 7" Display + TouchGFX = several weeks before anything started working 😅everything is so easy in the video

[@PhilsLab]

Haha yeah, those beginnings are tough :D

[@xxbatman69xx98]

@@PhilsLabI’m still in those beginning days. Everything is hard

[@colingale]

mine was stm32f4, it was a bricked and locked 3d printer display, erased it, wrote new bootloader+ ported a competing fw to the device which is upset the oem who then open up the fw to ge on o/s band wagon, failed and now do compatible device for the other "maker", win for reverse engineering and open source :-)

[@rallymax2]

I’m having flashbacks just reading this. Things have changed a lot and at the same time very little in 25 years.

[@vincentnguyen8083]

I remember setting up QSPI XiP on an STM32H750 a few years back, took a whole month to even understand how to start haha 😂

Very interesting tutorial on using an LCD in parallel mode with the STM32H743, thanks a lot Phil. I am just designing a EuroRack module with a touchscreen. Your clear explanation comes at just the right time! Thx!

[@PhilsLab]

Thank you - Eurorack with a touchscreen sounds like a cool project!

[@casualnoises2808]

@@PhilsLab I hope so indeed. I learned a lot from your tutorials on pcb design and the STM32 mcu family. It was thanks to you that I started PCB design, thank you very much.

Stm32 is the family, Phil is the maestro.

[@edgerokoth7234]

Phil I am so grateful for your educational content. Im currently on #127, #128, and you are such a billionaire when it comes to hardware engineering teaching. Im still enjoying your free courses, then hopefully advance to the fedevel courses. much blessings

[@PhilsLab]

Thank you very much, Edger - I'm amazed you watched nearly all of the videos!

[@gosdeCarrer]

I have started to use VSCode with the new official extension from ST, instead of the CubeIDE. It works very well. What is important, CubeMX, is the same. Configure everything, save and it updates the code. But edit and build with VSCode, flash and also debug. So far is very stable, (I don't know if there's still something not 100% covered). CMake is an advantage also, to adjust the build and all paths, instead of many mouse clicks in the old IDE. And the editor is much better and agile, IMO, (I have worked many years with Eclipse).

[@PhilsLab]

Interesting - I haven't tried that myself, but may give that a go sometime. So far, despite some 'oddities' I'm actually quite happy with the standard Eclipse set-up and haven't had a reason to change (yet).

[@EmbeddedEnigma]

always happy to see get notification from phil's lab.

[@andrefigueiredo4511]

Thank you, I was just studying about this few weeks ago and was struggling a lot. Your videos help me a lot!

[@PhilsLab]

Awesome, glad to hear that, Andre!

[@bsodmike]

Fantastic master class as always Phil, absolutely love your educational content. This is definitely giving me ideas. I've been working on a stackable baseboard design with FPC connectors, but I think I want to use a dupont header as well leaving the FPC connectors as an option. Reason is during the prototyping phase, the FPCs alone will invariably need breaking out again, at additional cost etc.

[@PhilsLab]

Thank you very much, Mike! Good luck with your project!

[@vbcoder42]

fantastic video.♥ first time i used a tft lcd i didnt know there were many protocols and just assumed all lcd displays and libraries support parallel and SPI. was an adventure to get it working (turns out it only supported parallel interface). had to try out many libraries and edit them to get it to work. there was no proper documentation for that display i picked up since at the time i chose the cheapest option. like i found multiple contradicting infos about it and its touch support.

[@PhilsLab]

Thank you! Yeah, the first time is quite daunting.

[@Ferreira019760]

Lovely video. Sometime in the future I personally would like to see a touchscreen for a similar application.

[@PhilsLab]

Many thanks! Touch screen part is definitely to come with this this display and PCB.

[@kiprof4350]

[@workethicrecords5901]

Excellent video. Speaking of all this memory stuff, I would LOVE to see a video in ST's XIP implementation on the H7 series. I've been diving in a wrestling with the provided templates, but it does seem very opaque, and ST doesn't have a lot of good documentation on the system.

[@PhilsLab]

Thank you! QSPI/XiP stuff is definitely on my list of videos to make, as the ST documentation isn't terribly good (especially when trying to use OSPI as QSPI as well...).

I know.. had to put both in the video title, as otherwise it also looks weird :D

[@MSP_TechLab]

28:30 I know that it heavily debated question, but I still can't understand why so many developers are so lazy to add a comment to their library. And yes, author of the lib has a beautiful post with pretty good explanation of configuration, but in any case something like "//start address of fmc memory" will give a little bit more direction of search.

[@andrewlloydwebber2616]

Thanks for the video!

[@PhilsLab]

Thanks for watching!

[@platin2148]

Uhh this looks nice, i choose to punish my self though and did go with MIPI DSI and seem to struggle with interfacing the panel. Driver for it would actually be open source as in is Kernel Mainline. It seems to use the SD2828 and a extra GD32 which apparently is the only thing they use for the display no DBI? Using the all new ESP32p4 for it..

[@PhilsLab]

I've yet to try MIPI DSI with STM32s, as I haven't really had a reason to do so.. Let me know how you get on!

Do you also plan to make video tutorials about the quad copter? :)

[@PhilsLab]

Definitely!

[@billyjoe3309]

Would be truly awesome if you could design an embedded device like this one but that can also recieve videofeed from the drone!

[@PhilsLab]

I agree - that's definitely on my list of things to build! Once this is fully up and running, I'll aim to make a revision with some FPV-style video.

[@billyjoe3309]

@@PhilsLab I can assure you it will be a MUCH appreciated video. It may even give you the most views. Reason is that there is no such solution out there yet. Lots of DIY projects exist, but sending high quality video to a microcontroller that handles the feed and also able to overlay graphics, that's not an easy task. I'm thinking sort of a "DJI-style DIY project" if you know what I mean. We all know that DJI has some serious technology. Very much looking forward to see where this series of videos takes you. I believe it will be a huge success on your channel!

[@PhilsLab]

Thanks - agreed it's not trivial! Should be a few fun videos to make and a cool project overall.

[@billyjoe3309]

@@PhilsLab I got a little excited so I did some research which I wanna give to you. The STM32 processor you have probably has some nice way of getting a camera signal, but if not then here's a solution. Drone cameras use composite video, atleast the ordinary stuff. No idea what DJI uses, they're on a different level. So from the drone camera transciever, you get a composite video stream that you can then feed to a ADV7280, which will then give you 8-bit parallel output which you can feed into the STM32. You'll be running LVGL which has "lv_canvas" which is a very simple and smart way of taking that camera feed (which is now in a buffer) and "connecting" that buffer together with LVGL. Making you able to do overlays and even move the video feed on screen around (drag) if you'd want to. Hope this helps. I look forward to the next video!

[@sachinkumar-eb9mt]

Hi sir. How are you?

[@PhilsLab]

I'm alright, thanks - how are you? :D

[@Helal_Tech]

Hi, Phil. I always see in your designs the silkscreen section have solid square silkscreen and the word is written as a hollow in solid silkscreen. Could you tell us how you make it?

[@PhilsLab]

In Altium and KiCad, in the text options you can select the 'inverted' option.

[@CraigHollabaugh]

Excellent video including going with 'old school' 8080/6800 parallel interface using the FMC. How 1970s of you. I've never seen such a complete coverage in our SPI/I2C world. My question is, did you figure out this byteswap fix before or after you had boards made? Thanks Phil.

[@PhilsLab]

Haha thank you, Craig. I had previously implemented this on other MCUs (e.g. U5s) and naively assumed the procedure would be the same. Had the PCBs in hand and then found out that this remap is needed - but luckily it was an easy fix.

[@CraigHollabaugh]

@PhilsLab lucky yes, Ive been down multi-day rabbit holes like this and it sucks.

I've been meaning to with the NRF chips - but haven't found a reason to use them in a project yet unfortunately.

[@mkenya_engineer]

Could you do one for BLDC motor controller with FOC based on STM32

[@PhilsLab]

At some point, yes - in the meantime, TI has an excellent series of videos on FOC on KZbin.

[@danielpihlquist2664]

Hey! Thanks you so much, really good stuff! What's your take on using an CC2500 instead of something like an ESP32 and ESP-NOW? (Asking because I'm myself using a CC2500 for a project, and I feel that I would receive this question should I try to sell it...)

[@PhilsLab]

Thanks! The CC2500 has a few benefits for this application, e.g. low-level/direct comms (compared to WiFi/BT), extended range, lower power consumption, latency, etc. In my eyes far more suitable for this drone/controller application.
