Thank you very much for you videos! Helps me a lot!
Definatelly would really like to see some of the more fancy stuff. Thanks for the videos!!
Can you write firmware without hal library?
What would i need if i wanted to program a chip itself ,with no board?
Rtos would be awesome! Also check out micro-ROS.
This channel is just fantastic. I've always wanted to learn this stuff and this is one of the finest resources I've stumbled upon. It's easy to find beginner tutorials like Arduino programming but when you get beyond that it becomes harder and harder to find good content and resources.
Thank you so much, Rohit! Yeah, it's hard to find resources that cover 'the middle ground' for STM32s, so I hope I can make some more videos on that.
The best stm32 tutorial on RUclips! Hands down!!
Keep up the good work. The best detailed tutorials ever. Never get bored I can watch your videos for hours 😍
Awesome, thank you very much Chiheb!
Mate, you're gonna groom alot of engineers with all this content. Essentially, helping people earn their way in the world. God bless you. Take care, and Thank you.
Thank you, Suva!
your stm32 videos are hands down the best on RUclips keep up the great work sir
Agreed! On a scale of 1 - 10, Phil takes his tutorials to an 11! (Spinal Tap Reference).
Amazing tutorial Phil! No wasted time, just clear and complete explanations. On the downside, now engineering managers are going to expect that we can crank out a complete project in 38 minuets.
Phil, you have excellent presentation ability on topics that are on a different level and it is rare to see such a thing. The video is excellent and professional and shows all the basic steps to get started. I'm sure everyone will also be happy to see how DMA is enabled and how RTOS is used. Your contribution to amateurs, students and beginning engineers around the globe is unquestionable.
Hi David, Thank you so much for your very kind words. I'm glad to hear that this video has been helpful - thanks again!
Great tutorial. It was tutorials just like this that helped get me into electronics a few years back.
This is some really high quality content/tutorial!
Thank you very much, Vinam!
I completely love your videos. Please continue these STM32 videos!
Thank you very much! More STM32 videos to come :)
@@PhilsLab Actually working on my first STM board, it's very complex with lots of functions. Using a STM32F7 driven by a LiPo with a high end display. Goal is smooth UI and handheld. I have never used STM32 stuff before so I'm new to the Cude software and your videos are really helping allot!
As someone getting into this your videos have been one of my greatest resources, thank you so much for creating this awesome content!
My pleasure, thank you very much for watching! Really glad to hear that. Let me know if there's anything in particular you'd like to see in future videos :)
Great video. Very few people go this way to explain things in a simple and detailed way. Expect more content from you!
Thank you, Rikil! More content to come very soon :)
Have been searching for content like this for a while now thank you for taking the time to provide such an amazing content .
Awesome, well thank you for watching! :)
A really nice overview! I'm going to go back and watch your earlier videos.
Thank you, Mark!
This is awesome, especially with the long tutorial on making a PCB. I struggled so much trying to figure out how to program and debug a cheap blue pill board. I couldn't find a straightforward tutorial on getting started. I spent countless hours trying to figure out what I needed to program and debug with stlink. Thanks again.
Thank you, glad it helped out! Yeah, it takes a while to figure this stuff out - but definitely worth it in the end.
Absolutely an amazing video! This really gives a boost in the right direction when you want to know more about designing a standalone sensor or control unit. I really hope you also want to make a video about how to deal with ADC and write the data to the flash memory. Again really helpful Phil!!
Thank you, Pjotr! Yes, I'll be making quite a number of videos relating to the firmware of this board. Next one is on DMA and FreeRTOS! :)
@@PhilsLab awesome!!!
Great timing. I just recently got a few of the WEACT modules. Great video and really helped me understand CubeIDE. Thank you.
Very glad to hear that, thanks for watching, Jessie!
Awesome video! I hope this will be a whole video series. The topic is not covered well on the internet yet, so I think the community welcomes it nicely!
Thank you very much! Yeah, hoping to show the basics of writing firmware and then to build up to actually implement something 'useful'!
Salute for your work and dedication. Thank you so much Phil's Lab..
Thank you!
Love the stuff you are teaching here... So glad that I discovered your channel!
Thank you very much for watching, Abhishek!
Vielen Dank für diese Video. Eine sehr gut beschriebene tutorial. Thanks Phil.
Danke fürs Zuschauen! :)
Please keep this videos coming. I'm learning such great things, that I couldn't find online before you! It's really rare to find someone who explains everything slowly, bit by bit(pun intended😅). Thank you!
Thank you! Very glad to hear that. Will definitely be keeping the videos coming! :)
I really want to get into the electronics and this software design. This is such a good video and so well explained. But hell i am confused, lost and amazed all at the same time lol
Super informational video, thank you very much! Excited to see what's coming in the future, cheers!
Thank you very much! :)
Its here and at Ben Eater's channel that I get content that very few give/or dish out properly, great staff!
Thank you very much!
Started playing around with stm32f3discovery with rust, I am really into embedded right now and this is quality content
Awesome, thank you!
I really enjoy watching it, thank you Phil!
That's great to hear, thank you!
While more advance subject is more my cup of tea, I really appreciate what your doing.
This would have help me a lot when I was beginning.
Thank you! Yeah, just trying to cover the basics before moving on to actually implementing something useful (and more advanced) :)
@@PhilsLab Yes. I saw your last video using FreeRTOS and DMA. Those are definitely more advance ^^
Looking forward seeing more RTOS-driven software design.
best channel for pcb boards!
Hi Phil. Great video. the 40min more productive of my weekend. thanks so much for sharing your knowledge.
Awesome, thank you, Mauricio!
Yes please, more STM32CubeIDE C-programming tutorials !
More to come! :)
Another top video -thanks for posting. Having recently decided to get back into microcontrollers (I'm 8051/8bit PIC vintage!) I'm a bit overawed with how far things have come. It's more akin to programming a full blown computer but with access to the peripherals than a "traditional" microcontroller. Now I'm feeling very old!
Thank you very much! Indeed, it's crazy how much you can get for so little money these days. ST has now even introduced the STM32MP1, which combines a MPU running embedded Linux with an MCU in one package for under 10 EUR for the cheapest one. Pretty crazy!
Great video... I would really like to see the entire board populated and in full functionality. Hope to see that soon. Keep up this awesome work..
Thank you! Yes, I'm planning on using this board for the next few videos with the functions combined.
This is the most clear and simple explanation on stm32 MCU!
Waiting for quaternion math on IMU calculation routine.
Thanks!
Thank you! Sensor fusion video coming soon! :)
Really Cool project, really well explained and presented as usual. Great work! :D
Thank you, Rasmus :D
Super video! I've been so busy learning atmega328 chip so I haven't had the time look into STM yet but I really want to learn STM32 mcu's so this was perfect.
Awesome, yeah I think it's well worth getting into STM32 MCUs. So many doors open (so to speak) when you make the jump!
Hey Phill. Great video. I am learning a lot. Please make a video on USB bootloader and firmware upgrading through USB if you get time.
Great video, nice to see some one reading the data sheets this seems to be a lost art. Proper embedded firmware design being talked through. well worth the time to watch.
Thank you very much! Yeah, I try to write the drivers from the firmware as opposed to just copying from another source. Not sure how other people do it though!
@@PhilsLab You hear a lot of "I’ll wait until a library is available"
Really great content. Detailed and well explained. Thanks!
Thank you very much!
Hello Phil
I usually never write comments on RUclips videos, but I just really wanted to let you know that I really enjoyed this one. I've never even touched an STM32 (i know my way around C but thats it) and I've sat here for the entire time just being amazed of how well you explained everything, even though it looks quite complicated. This video motivated me to now order such a board and maybe play around with it a little. So thank you for that!!
Thank you very much, Samuel! Very glad to hear that these videos have been helpful. Hope all goes well with your new board :)
Awesome video. Great instruction and explanation. Thank you!
Thank you very much, Adam!
Phil, your videos are absolutely amazing and very educational.
I'm looking to exclusively use the STM32 for my client's projects because of the low cost, high performance and lots of support online. Your video show that I'd be making the right decision to use the STM32 microcontroller series with the ST-LINK/V2 programmer for in-circuit debugging, break points and single stepping through my embedded software code. Thanks for your videos and tutorials.
Thank you very much! I'm very glad to hear that.
Yeah, before settling with the STM32 line of MCUs, I had a pretty long look around for the best MCU manufacturer (in my eyes). Just the fact that things like CubeIDE, HAL, etc. exist made the choice pretty clear to me. Also, the fact that the debugger is so much cheaper than most debuggers available..
Hope all goes well with your STM32 designs! :)
@@PhilsLab If I remember they make an isolated and a non-isolated programmer. Do you have a recommendation?
Your videos are great! I was looking exactly for this. Thanks
Thank you very much, very glad to hear that!
Fantastic video!! It was very informative.
Thank you, Peter!
@@PhilsLab Have you done any STM32 boards with an Ethernet interface? If so, how easy was it to get going?
Thanks for your nice explanation. That actually helps me a lot! Subscribed.
Awesome, thank you :)
Grate work ! Keep on going, your videos are helping me so much in my graduation project, Thanx for your efforts :D
Awesome, thank you - very glad to hear that! :)
You are VERA LEVEL BRO!
So Awesome! A lot of love from my team!
Thank you very much!
Nice video!! Great detailed explanation! Thanks again
Thank you for watching, Fernando!
Excellent video, thank you! You are insanely productive.
Thank you very much!
hi that was a interesting video i've just got into stm32 micro-controllers so this is use full info look forward to seeing more of your videos
Thank you, Glynn!
Very nice, deep and clear overall tutorial. Right now I am learning MC such as STM32 and this gives me goosbump to interact with boards.
Could you please also make a series or a video regarding basic concept of Hardware Design Engineer. I am making my career in this field. When I making circuits then so much confused about the components which are connected with ICs and other components.
Thanks and appreciated..
Another great video! Thanks a lot! Inspired by your STRF video, I recently designed a really tiny board with the STM32L0 and the NRF24. I'm really amazed by the quality JLCPCB delivers for only a few bucks. Also debugging the STM32 appears to be much faster than the PIC microcontrollers I used in the past.
Thank you very much! That's awesome, did you get the boards already? Yeah, it's amazing how inexpensive assembled PCBs are with them - I just wish that they'd start offering assembly for 6-layer PCBs soon..
@@PhilsLab Yes, got the boards last week. They look great, but only had time to roughly test the SPI communication and turn on the transmitter in CW test mode. Unfortunately, I have to prioritize paid projects :-) Assembled 6-layer PCB would allow for some very interesting designs!
@@PhilsLab what kind of great projects do you have in mind, involving 6-layer PCBs? 👀
I just found your videos last week! Thank you for putting them together. You're empowering us to make our own boards and program them too! Definitely not as scary as I originally thought. I'd love to seem more fancy stuff, like using DMA and an external ADC board design design. Or High Speed USB phy on an stm32f405.
I'm working on reverse engineering some hardware and will need to make my own board to fit an existing enclosure, so your videos are perfectly timed for my needs thanks!
Thank you very much for watching! Very glad that you found my channel.
The new firmware video covers a bit of DMA stuff. Definitely would like to make a video on interfacing an STM32 via DMA with an external codec as well.
@@PhilsLab i already watched it, and even followed along with a nucleo f411re board. I haven't ordered one of your f405 little brains yet. But I plan too once I save a little. I hope to finish my design for my gpio dma project first so I can order both at the same time with JLCPCB.
Dude, this is really cool!!
This is what i wanted to see !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Great Video !!!
Thank you, Marcin!
Excellent video. I wish there could be a long tutorial series for using STM32Cube software with a more complete set of peripherals.
Thank you, Sumit. More videos on programming STM32 MCUs to come this month! :)
Hi Phil! Thank you for share with us this nice and really good presented video. I'm excited to see a RTOS running on this board. Also it would be awesome if you make a board using STM32 interfacing with a Sub-GHz transceptor and some sensors to create a generic IoT node.
Thank you, Luan! RTOS + DMA should feature in the next video :) I'm afraid I'm not much of an IoT guy myself so am planning on doing a couple of other videos first - hopefully all of interest however!
Very interesting. Thank you it was very helpful and informative for me, a newbie comming from Avr 8bits.
Awesome, thank you for watching!
Thanks for sharing this victory walkthrough
👍😀
Haha thank you, Asger!
Thank you so much Phil's Lab
Thank you for watching, Emre :)
Great tutorial. Thanks alot
Would you do a video, or have you done a video, explaining in more detail about how you test your new board for issues with voltage and current? I'm sure it's hard to condense so much into one video, I really appreciate the knowledge you share!!!
Thank you so much for your time and effort
Thank you very much for watching, Liam!
Very nice video Philip, tnx 👏 👏 👏 👏
Thanks for this tutorial, it is really great for beginners.
Thank you!
Thank You! From Frisco Texas.
Good stuff! Thanks!
Beautiful board
Great! Thanks for sharing ❤
Thank you for sharing Phil! All your videos are pure gold IMHO 👍🏻
Just a quick question: did you leave out the flash memory programming for a future video?
Thank you very much, Bastiaan! Yes, I left out a couple of things on this board for future videos, but planning on making them soon :)
Wow, im excited to see the driver for the flash memory!, will be waiting for it. Thanks for the interesting video
Will hopefully be doing that in a future video, thanks for watching!
Yaay brother .Thankyou so much for the tutorial 👏👏👏❤
My pleasure, thanks for watching!
@@PhilsLab Eagerly waiting for more videos related to stm .Thanks for teaching .
I love this video thank you ❤
Thanks. This information is actuality
Thank you!
justo lo que necesitaba, thanks
Very useful thank you
Awesome video series, this really has helped me learn kicad and the fundamentals of designing PCBs with stm32 microcontrollers. In a future video, can you go over using a USB type C connector with an stm32?
Thank you, very glad to hear that! I haven't had the need for a type C connector + STM32 just yet, but maybe sometime in the future. :)
If you have an STM32F3 Series Nucleo Board, you need to enable PG6 as it controls a pull-up resistor for a data + line, didn't realize until I read the documentation, all I did was toggle the pin in my setup, Also I realized that the bottom micro USB receptacle doesn't need power, I have a switchable on off set to off and the bottom USB port and it was still outputting to the virtual com port despite it being off.
Absolutely an amazing video! I suggest to make a tutorial for the CAN BUS interface.
Thank you! Yes, CAN is definitely on my list of things to make a video on.
@@PhilsLabWhat's the relative cost of your board in comparison to STM's dev boards?
Really great tutorial.
If I may suggest you make a tutorial for the CAN BUS interface.
The STM32 has a great CAN and CAN-FD interface on its microcontrollers.
Thank you! Yes, definitely want to make a video on CAN at some point!
Great project!
One thing to do it better would be controlling light intensity in a nonlinear scale (gamma corrected). Human eye has a logarithmic response curve ~ x^1/2.2, so in range from 0 to 100 value 22 is perceived as a half.
If power function pow(x, 2.2) (x in 0.0..1.0) is too slow you can use approximation:
y=0.8*x^2 + 0.2*x^3 with max error < 1%
or
y=x^2 with max error 3.5%
Great video, thanks
Thank you for watching!
You can force USB to re-enumerate by pulling the USB data lines low for 100ns. You will have to reconfigure the gpio pins of course which is a bit annoying but it's easier than fiddling with cables. I believe it's called a "Single ended zero" in the USB literature.
Inspiring, thx
Thank you Phil.
My pleasure, thank you for watching!
this is more complicated than i thought but it's worth learning
very good information
Thank you!
This is gold!! What are the next steps? Which topics you wanna cover?
Thank you very much! I'd like to make a video on RTOS + DMA and then a couple videos on things such as real-time FIR/IIR filter implementation, extended Kalman filtering, etc.
@@PhilsLab That would be SWEET!
@@PhilsLab Hey Phil Thank youuuuuuuu for your great video again that so exciting to hear you will make some videos about RTOS, could you also cover some video about CMSIS FreeRTOS?
@@PhilsLab I am very excited for this! Since I study electronic engineering, it's very difficult obtaining such high quality YT resources as yours on slightly more advanced topics.
@@PhilsLab woow. Looking forward to seing those vidéos
great video
Thank you :)
That so cool :D I only worked with STM32 briefly, before I caught the build it all out of TTL bug lol.
Thank you! Well hope this video can get you back on the 'STM32-train' :D
Thanks for the info..👍
Thanks for watching!
Can you make a basic tutorial about using the IDE, and what all clock frequencies setting means, how to select proper pins, etc.
Hi Priyank, I'd think there's quite a lot of information on the internet regarding that, so probably not, sorry - I'd like to cover more advanced topics in future videos.
So nice
great, thanks for invaluable stuff, I would love more of this king of thing as would like to play with STM MCU's perhaps some more beginner stuff would be popular ...cheers.
Thank you very much, Andy!
have a look at LP5523 for RGB LEDs - it's a 9-channel driver, with built-in charge pump boost, so it can run up to 4.5 V on 6 of the channels, 3 channels connect to Vdd directly... has many interesting features, is very programmable for LED effects without CPU cycles, after programming and start. automatic temp compensation, channel grouping... very good to write drivers for, and you could find drivers for it on-line, as it was used in Nokia phones
And, it's in a small package, about 2.7 x 2.7l
Great work!
I'm using cubeIDE too and that's very convenient IDE to work with because the cubeMX hasbeen integrated, and can use dark mode lol
BTW i'm waiting for section where the mcu interact with ext spi flash, it would be interesting!
Keep it up!
Awesome, thank you! Yeah, CubeIDE is just really convenient to work with.
Thanks for the suggestion, will aim to make a video with that in it!
Hi, could you please give a more in-depth explanation of how u configured the clocks?
Thank you for another great video. Do you think you could go over how you figured out how to wire up that memory? And how to interface with it?
It's just an SPI memory chip, so uses simple SPI bus like anything else. Loads of libraries and arduino code examples for using them
nice tutorial
Thank you!
