One very important thing that wasn't mentioned: You need to install drivers for your programmator/USB>TTL converter. By default there is no USB driver which would translate the serial signal and you will be getting port errors while trying to upload your code. If you don't know this you might waste hours trying to debug the wrong things and might come to a false conclusion that your STM32 is broken.

I have been following this channel since you had about just 8 videos. No other youtuber that I know of makes videos as good as you do. Your videos are in a class of its own. I look forward to seeing more of your work.
Great Scott!! Great video!Of all the stm32f103 videos I have viewed, you gave the most info and also using leaflabs makes it easier to continue learning about the board. Thanks for sharing
Very happy to see the STM32 getting more attention.
An additional thing to note is that most of these boards actually have 128KB memory instead of the documented 64KB. Thats a lot of space ! but your luck may vary.
BTW, using an ST-Link to program the board is a lot easier than fiddling with FTDI boards and jumpers.
I simply don't know how you do it, but you make videos about a subject a few days after I come to know about it!
I received my STM32 board a few days back.
i have no clue how he does it but he seems to make videos on a subject only 5 years before i learn about it!
I had been considering the Blue Pill Arduino for a while now, but you convinced me to order some from Amazon. Thanks for you time and effort in creating this video guide.
as I'm doing internship in STM I really appreciated this video :)
How in the heck do you ALWAYS give me the exact information I needed for my new projects in every new video you put out? Interrupts are exactly what I'm looking for!
This chip (STM32) is also used in the iconic Naze32 flight controllers for drones. It's known as an F1 board, we use the new versions of the STM, like the f405
thank you for the testing. always good to have another board to look after.
I just love JLCPCB as a sponsor for your channel. It fits so well to this channel, you get that money for these videos and you don't overuse/overadvertise their services
I had no idea that the STM32 in this form existed, even though much of my work in embedded systems in the past has been centered around the cortex. I went and ordered a few of these to have some fun with - thanks for the suggestion @GreatScott!
lol i love your videos, they are so calming and satisfying to watch. And i always learn something new :)
Great Video. One of the Blue Pill's best benefits is that it has a WS2812 library that is timer/interrupt based. The Arduino utilizes program instruction timing to create the waveform needed, but that requires them to disable interrupts. The Blue Pill has no problem servicing external interrupts while driving the led strips.
Thanks for the product review. It's always good to know there are alternatives that can meet more demanding PWM applications.
Love your videos bro! Many of your videos have helped me come up with new ideas on how to make my personal projects better :) keep up the great work :D
Finally you upgraded your highlighter, good job man
Just ordered four of these.
No clue when I'll use them, but I can see how these would be great for embedded systems in the future.
Man. When I made a project with the nucleo dev board, I had to set up my own tool chain and I wrote the entire code for communicating with the peripherals myself. Good to know this exists!
like always great explaining, great videos, GREAT SCOTT!
Thanks GreatScott for uploading this kind of video.
Thank you GreatScott, it was a great instructive video, I wanted to use STM32 in my projects but I haven't found a great beginner's guide like yours. Now I know exactly what I'm going to do to develop STM32 projects. Thank you.
This is a youtube channel on Firmware development for 8-32 bit MCU and IoT.
Explanation of sensors , modules, pheriferals from datasheet
Do have a look into it : th-cam.com/channels/aRUL90bhP-TdCLUlla3gMg.html
Fantastic video. I learned more in 10 minutes then hours of fumbling around on the internet. Thank you for sharing.
Do you know how good your straight lines and hand writing is MAN I AM JEALOUS!!
Great video, everything so well explained and thanks for all the links.
Stm32f4 discovery boards are powerful little beasts. Used one with an Arduino in an autonomous vehicle class while at university.
OMG a new video after 1000 light years . Dude i m so excited when You post a new video . You make a very grate job . Keep up the work 😃
light years measure a distance
i know.... a distance from the videos :))
Another great video! Definitely will be checking these out.
Great job! I was wondering when you would try this board!
Thanks for bringing this to our attention. I've bought 4 of these to see what they can do :) cheers!
Thank you for another inspirational video! For those interested: in video #11 Andreas Spiess compared speed/power of ATmega vs. STM32 vs. ESP.
Excellent Video my friend!!! Just got my hands on a couple STM32 Boards to add to my Arsenal and I was a little worried that writing sketches would be significantly different from Arduino! This video cleared that up nicely!!!
Good shout man. I'm not sure for now that anything I plan will require the better resolutions etc, but it's good to know that if I require a higher fidelity, there's a decent similarly priced option out there - without me having to go searching among all the other solutions out there. Cool vid, thanks.
Thank you for this video, I was interested in this microcontroller a while ago when I started to out grow the nano but was hesitant because of the scarce documentation and support
Thanks guy! Great video, plenty of golden information!
I personally use the NodeMCU ESP-12E and i love it! it functions pretty much like a uno, and has wifi built-in. plus they cost $2.40 on aliexpress
very nice & clear explanation, Brother Scott ...
Can you do a video showing the nucleo stm32 boards? They range from the ARM Cortex M0, all the way up to the 400MHz Cortex M7. And even the M7 is cheaper than a Nano from Mouser Electronics.
I work for Mouser incidently, I could mail you some Nucleo boards if you'll make a video. I'm too inexperienced to know how to make the jump from Arduino IDE to programming these things.
I agree. I have a couple of the Nucleo boards (NUCLEO-F746ZG) to play with. I couldn't resist trying them based on the hardware specs, but find them to be a little harder to deal with at this stage in my microcontroller learning process. I was making decent progress but os.mbed.org quit compiling temporarily and I went back to Arduino...
Yes, I love my Nucleo boards (F411RE and F446RE). Nucleo boards are relatively well supported by mbed and few other real time OSes. What is cool on those Nucleo boards is to have the hardware to really be able to debug it, the price is competitive and you can have a lot of IOs and interesting features: Fast ADC, Correct DAC, I2S, CAN, Ethernet on the Nucleo-144 series. I am using mbed, www.openocd.net/ and github.com/texane/stlink to program.
Absolutely love my stm32 nucleo boards. They are cheap, superior and powerful in every aspect.
Julien Boucaron I would suggest you to try Keil Microvision to program them
it works as well as atollic truestudio, but you can get it for free
And with the STM HAL Library and CubeMX configuration Programm they can be quite easy to program
Unless you want to get a stable CAN connection and you have to go back to the old Library's..
Here is a nice start:
trinirobotics.com/category/stm32-microcontroller/
Looking forward to some great projects in the future. There's gold in them thair hills!!
Thanks so much for this video! You're the best.
Thanks for the helpful overview! We're learning all kinds of fun things about the STM32F1xxx processors as we're working on porting Marlin Firmware to various 32-bit MCUs including this one. The lack of 3rd-party libraries definitely makes it more challenging. Nevertheless, we're making progress and have it mostly running at this point. Considering the large size of Marlin compared to most Arduino applications, I'm impressed that it has been relatively quick and straightforward to refactor most of it. After we get past the first hurdle of getting everything running as well as AVR, then we will be able to start taking advantage of the extra timers and other capabilities offered by these more powerful platforms.
If you're one of those responsible for making Marlin 2.0 available for the ender3v2, thanks so much! It's a great firmware for those who want to customize lots of things but not attach a raspi to the printer like with Klipper etc. The stm32 boards are amazingly cheap as well and are really fun to use for all kinds of projects.
STM32 minimum system is also very useful 😊
Your Videos are Really High Quality and Rich Content with Lot of educational Stuff...Thank You #GreatScott!!
You're welcome :-)
If you want to get a little bit complicated. One can also use ST link programmer along with STM CubeMX and Keil IDE. In that way you can get full outcomes from that ARM STM.
More informative about STM32.
Thank you.
Just so you know, I have a playlist of videos I have been compiling for some time based around electronics and you represent 95% of my list
+Cody Deforest Haha I like it
Thanks for another amazing video, always following your channel
Awesome :-)
Really good video and explanations, thank you!
Nice video! I'll be trying one of these soon.
It is a great vídeo. Thank you. Recently I bought 3 stm32 from aliexpress. I am waiting for them.
Now we need a ESP32 guide!!! nice video Greatscott btw youre the best
I did a small ESP32 guide. Here it is: th-cam.com/video/ZAqNKaX3LQ0/w-d-xo.html
Gotta check that right now. Keep up the awesome work!
Hi Scott, thanks for the great videos that you upload :), always interesting.
Great video and love you Scott
I purchased 2 of these a year ago, cool concept, but never used them with Arduino. In think that they are more useful using STM32CubeMx + eclipse + STlink. Proper IDE, proper HAL. I know that your channel is not oriented towards what im thinking, but I see it as the natural progression. You got yourself into electronics by arduino and later on you go deeper by learning what a microcontroller actually is. Discovery Boards are also a great way to get you into STM32 microcontrollers !!!
cheers !
What’s the difference in power consumption?
The magic of BOOT0 pin moved to '1' is that there is a serial bootloader installed on the chip by default at that location. For those with usb ST-LINK programmers, you can mostly ignore that OR use st-link to replace the bootloader with whatever you wish.
You gotta love the signatures from top TH-camrs: "VSauce, Michael here..."; EngineeringExplained: "Hellooo everyone, aaand welcome!". I always make sure I stay till the end of GreatScott's videos, just to hear "Stay creative, and I'll see you next time !" - funky intonation and all.
We used the stm32 in a control systems lab at my university. Except we coded it in C. Now that was a challenge
It would be awsome if you made a video about FPGA's
ya FPGAs for the WIN !!!!
Little did he know.... the comment came true.
Thanks for the info Scott :)
Very interesting! I was unaware of the arduino IDE compatibility! Since STmicro took over Atollic, TrueStudio PRO is now free to use with STM32 MCU's! This IDE has very powerfull debugging capibilities and also very easy to install in Ubuntu! Might be interesting to take a look at that!
yeah mate i got it installed. im still figuring it out. it looks like it has my wee blue pill board available. but im kinda running in bareback and seeing what kind of crazy shit i can get away with. still somewhat lost.
Really useful! i was looking for a faster board to try a "current chopper" like the one you made in the brushless edc video, but measuring the current with a shunt resistor
Nice comparison of the general feature. What's missing IMO is a comparison of power consumption, for example if one wanted to run those boards on batteries.
Granted, as the STM32 will get a job done faster due to the higher clock speed it's not an easy comparison, but a base line of maybe one of your sketches would be nice.
I clicked ur bell! Your great Scott.
Hey I reached a bit late but again excellent video learned new things and as usual keep it up
Set your timer's ARR to 7199 instead of 7200 for an interrupt per second. Its a small difference but can make a difference in the long run.
I switched from Arduino to STM32 back 4 Years ago and never looked back. Especially the Eclipse/GDB/Stlink-Combination is unbeatable and by not using the Arduino Library you also get a massive performance boost.
have you been able to use any DSP libraries? i'm attracted to the CMSIS DSP libraries but the whole CMSIS or HAL thing confuses the crap out of me
You can also program these MCUs with the Rust programming language as well as C. It's great to be able to use a high level language without sacrificing performance or code size... You can even mix both languages in the same project...
exellent video. as a producer of videos too - I could really see the amount of work you've put into that - be interesting to know how long the shooting/editing took - my guess is 5-10 hours. probably more towards 10 (note: not effort of finding code, experimenting, getting it all working - that obviously was much longer!). keep em coming!
I'm about to finish my first Arduino class and even though I find this interesting, the terms used in here are new to me. I really learning from people's comments!!!
Would this micro controller be suitable for beginners? I am looking for inexpensive Arduino arlternatives for different projects I'm planning on doing based on GreatScott projects
I like those STM32 boards. They are very cheap, powerful and overall they are like Arduino Nano on steroids.
In my opinion there are some things that still make me get and use Nanos instead of those STM32 boards in most cases. For example Nano's external USB-to-UART -converter is a pro and a con. Can't make HID devices with it, but it allows having serial port present on computer side, even during the reset (of the microcontroller). Also the possible compatibility issues with libraries can be annoying.
Anyway, great comparison and video.
Very informative. Thanks for sharing
Great video. I did not know about this stm32 and that it can be programmed with the for me very familiar Arduino IDE. Ordered a few of them.
Thank you, I bought one of these on an eBay buying spree a year or two ago and never got around to messing with it. Sounds like I should consider using it instead of the Nano as my default device in projects. Have to see how it does at low power though.
John Ridley it actually performs better than Arduinos in low power situations thanks to the cortex m3 core. In fact it can make it to a couple microamps in full-on sleep mode
Thank you! Great video. I am a analog /digital engineer but have not used any of tyhe ne Arduin type stuff. This video excited me so much I am going to buy the parts you used in your demonstration right now, 2-12-19. What monitor did you use to see the potentiometer values?
This video helpful for me so mach. I'll begin to learn STM32 Chip.
Man you have in depth knowledge and great patience to make that video's 👍
I am 0
Please let me where I can start learning.
Perfect timing I'm looking at STM uC for two projects. Danke schon! Aber the 'blue pill' some-one might get the wrong idea if I said I was getting some blue pills!
The STM32 is my favourite MCU to date (I however program it without the Arduino IDE). I've totally fallen in love with the ARM architecture!
Bro I'm confused right now I wanna buy this bourd but the not enough library thing is bothering me right now and im not a very good coder so can you tell me how can I get this to work? In any kind of project?
Outstanding! Thank you!
Another informative video! Thank you! I have just started getting interested in using micro controllers like Arduino recently but have not yet taken the plunge. Do you think going straight to this is a better option given price and availability? Or do you think Arduino is better to learn and practice on then when I am interested in more powerful projects I move to this? Or do you think it may be best for a beginner to start with Arduino Uno? I have read that the Nano and smaller boards can just be a bit fiddlier to work with.
You are a good teacher,.
Thanks
If you plan on using these regularly I recommend getting an ST-LINK programmer. The clone ones work well and cost
No, it's not serial like an Arduino, it's a protocol called SWD. You need an ST-Link like this one. www.amazon.com/Electronics-Emulator-Simulator-Programmer-Programming/dp/B072J7QKDJ
You need two if you want to flash the Black Magic firmware.
Great Video Scott thanks!
Love watching your videos great...
Now waiting for the next big project where you will make an awesome (as always) project that needed the STM32 because the Arduino couldn't cut it
Morad Tamer I can see the coil gun with other features
Thanks to this video I realize why my first attempt with the STM32 failed.
Great video !
I never see you use the DIY soldering station you built. I liked this project. Is something wrong with it?
Thanks for your advice
OMG you drive me crazy with the high lighter pen.
There's a 16-bit timer on the ATmega328 that's not exposed to the Arduino IDE; other than hidden in the servo library. I used the 16-bit functionality in a proprietary project; it wasn't too hard. Being a glutton for punishment, I even developed an I²C connected ATtiny85 that'd drive a PWM at any frequency (over the range of 15Hz to 30kHz ), at the nominated duty cycle. Even had a spare interrupt for tacho feedback where available, but didn't get around to implementing closed loop control of speed; development time being the restriction, not a lack of chip facilities.
BTW: The PB version of the ATmega328 chip has more external interrupts, timers and UARTS, another I²C and some more goodies but is unfortunately not pin-for-pin compatible, employing some of the "duplicated" power supply pins for I/O. So you can't simply replace the microcontroller on a PCB.
When comparing the options, it's also necessary to look at the power consumption; especially for battery operation.
If you need the raw computing power or the many interrupts, or the finer ADC resolution then obviously take the STM32 option.
I use a set of tables to *plan* out the required microcontroller resources for a project, detailing I/O - input/output - analog/digital, interrupts, hardware timers and their respective allocation. Then I choose the microcontroller. The tables can start out on a whiteboard next to a rough map of the electronics before I migrate them to an electronic document. I stick printouts of the tables on the wall next to my desk while programming. Paper being slightly cheaper than the equivalent 70" LCD. ;-)
Thanks for featuring this, can you feature how to uses the Can Bus to communicate to another Arduino
Scott, u are great !
Scoot you are the best.keep going
Danke fûrnso viele Tips, Maestro, looks like some good documentation available from the sources that you mentioned! Have you done any low-power testing on the Blue Pill? I used to use hc11 processors, and some others, and got used to the uA range work when I worked in the "mobile phone" world... BTW, if you want a very nice LED driver, look at the L5521/5523 (3 ch/9 ch) from TI; these are programmable, via I2C, with three "engines" that drive the LEDs, even with you CPU powered down, or in 'sleep' mode
I have a desk littered with Arduinos and Pis. Now I want some of these too.
Daaamn, this board is even cheaper than arduino nano on aliexpress (arduinos are quite hyped this days). Thank you for showing an easy way to programm this bad boy)
I like the Node MCU which is based on an ESP8266 which is a similar price and you can program in the Arduino IDE over the USB port. I also like the Nucleo boards for anything that has to come from a reputable source, you get something seriously powerful and it's just £10-12 from Farnell. That doesn't support Arduino and you have to use mBed instead, but it's very similar with most libraries I use being supported.
These are fantastic project devices. They come in several flavors. I have used them to make several one-off automation devices. We need a PieHole app for it. Instead of blocking adverts the PieHole plays and watches them so I don't have to.
