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.

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

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

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.

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

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.

as I'm doing internship in STM I really appreciated this video :)

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.

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!

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.

thank you for the testing. always good to have another board to look after.

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.

Do you know how good your straight lines and hand writing is MAN I AM JEALOUS!!

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!

Fantastic video. I learned more in 10 minutes then hours of fumbling around on the internet. Thank you for sharing.

Thanks for the product review. It's always good to know there are alternatives that can meet more demanding PWM applications.

Stm32f4 discovery boards are powerful little beasts. Used one with an Arduino in an autonomous vehicle class while at university.

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

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

lol i love your videos, they are so calming and satisfying to watch. And i always learn something new :)

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

Thanks for bringing this to our attention. I've bought 4 of these to see what they can do :) cheers!

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.

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.

Thanks GreatScott for uploading this kind of video.

Great job! I was wondering when you would try this board!

Another great video! Definitely will be checking these out.

like always great explaining, great videos, GREAT SCOTT!

Great video, everything so well explained and thanks for all the links.

Finally you upgraded your highlighter, good job man

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.

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

Thanks guy! Great video, plenty of golden information!

More informative about STM32. Thank you.

It is a great vídeo. Thank you. Recently I bought 3 stm32 from aliexpress. I am waiting for them.

Thanks so much for this video! You're the best.

Looking forward to some great projects in the future. There's gold in them thair hills!!

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 !

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

very nice & clear explanation, Brother Scott ...

You gotta love the signatures from top UKpostsrs: "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.

Nice video! I'll be trying one of these soon.

Really good video and explanations, thank you!

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.

This video helpful for me so mach. I'll begin to learn STM32 Chip.

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.

Hi Scott, thanks for the great videos that you upload :), always interesting.

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 😃

Very informative. Thanks for sharing

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.

Your Videos are Really High Quality and Rich Content with Lot of educational Stuff...Thank You #GreatScott!!

Outstanding! Thank you!

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.

Great video and love you Scott

It would be awsome if you made a video about FPGA's

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.

We used the stm32 in a control systems lab at my university. Except we coded it in C. Now that was a challenge

You are a good teacher,. Thanks

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...

Thanks for the info Scott :)

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!

Thanks for your advice

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!

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.

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.

Thanks for another amazing video, always following your channel

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!!!

Love watching your videos great...

Great Video Scott thanks!

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.

I clicked ur bell! Your great Scott.

Great video as always, you explain the PWM part of the STM32 really clear especially on the timers and frequency.

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.

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.

Thanks to this video I realize why my first attempt with the STM32 failed.

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!

OMG you drive me crazy with the high lighter pen.

Now we need a ESP32 guide!!! nice video Greatscott btw youre the best

Hey I reached a bit late but again excellent video learned new things and as usual keep it up

Thank you. that was very helpfully to me. Really U great.

Thanks for featuring this, can you feature how to uses the Can Bus to communicate to another Arduino

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?

GeatScott is all time GREAT !!

Scoot you are the best.keep going

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.

Scott, u are great !

I love smt32!! I have the smt31 but really want upgrade

great video....more video projects using this board. !

Dank you very vielmals :-) I often see them and see the specs and the price but had no clue about them and because I am like a classic Bauer "was er nicht kennt, frisst er nicht", I kept my hands away from them, but now... man only the nine more pins and integrated usb... just imagine two Nokia LCD's on one uC, I already have a picture of diy soldering station 3.0.

I just ordered mine yesterday.....time to program

I have a desk littered with Arduinos and Pis. Now I want some of these too.

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!

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.

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. ;-)

Thank you!
