Arduino for STM32 + MPU-6050 == Improve your programming skills! 

Great description of 2's complement. After 40 years I've still been complementing the lot, then adding 1 to get the magnitude result. Just using -128, or -32768 for the MSB - sheer genius!

Underrated channel

There are lots of clever people, but not many who are able to pass on the knowledge efficiently. Thank you Joop!👍

The validation of the i2c was really inspiring.. Great video for everybody who is looking for "where to begin";-). Thanks Joop! Great Work!

Awesome! So clearly explained. I liked that you showed what the problem was then how to fix it instead of just doing the code in its finished state and not explaini g why these things are done. Thank you!

Nice explanation on two's complement, that was the easiest explanation I've come across. Seems obvious now.

I never understood that two's compliment is that you just invert the sign of the value of the high bit. Quite why I haven't come across that rather important simple detail before is beyond me.

Best explanation I've ever seen on microcontrollers on RU-vid.

Thank you for the excellent explanation on why pull-up resistors are necessary. For me, a newbie, this was a huge "ah ha!" moment.

I had a similar problem when I was using an I2C sensors with STM32F429 Disco board and had to change the pull-up resistors to 1.5K ohm to enhance the stability of communication between the MCU and sensors because I was using a long wires for the I2C bus. Very nice video.

So gladly I found this channel, most people just library everything and the supposed tuttorials are very vague, Joop in other hand have a completely different approach, simple but down to the roots of the thing

*I've been waiting for this since eternity, continue with STM32 as it is the future, similar to Arduino, back in 2007.*

As always, an extremely high quality tutorial. Please keep up the good work as it is very much appreciated.

Hi Joop ! Thank you for being patient to talk calmly and not rush when saying things it makes it much easier to understand and you take your time to teach very detailed that`s why i subscribed at once after watching this video. I learned a lot. Nice job! Are you the Joop that is interested in making PI metal detectors? If you are I would just love to see you make a video series and teach with that topic and use the stm32 for that purpose! I would appreciate it alot. Thanks again .

Great extra level of detail on I2C pull-ups w.r.t. clock speeds and the 2's complement stuff. Thanks so much :-)

Excellent video. Engineering quality , where also experienced people can learn important things.. Greetings from DE.

The first thing to do with a "Blue Pill" stm32, is to put the Maple USB bootloader on board, so you can power, program and debug through the micro USB bus. Nice note there ... putting extra pull-ups on the i2c lines to improve speed. I've read that the pull-ups should go closest to the lowest voltage device.

This was a great set of problems just about anyone is going to face moving to a platform with different data width! Thanks.

great easy work ,that shows how deep your understanding is. CAN I ASK what your Profession ؟ is

Very informative tutorial. Thanks also for the 2's complement explanation.

8:58 If I'm not wrong, there is small correction I think '0' represents 'Positive' and '1' represent 'Negative' "Most Significant Bit" in 1s as well as 2s compliment.

2019-12-11: I've just bought a couple of those same modules, those two pull-up resistors are now 2k2, they must have seen this great video Joop :D And the frequency is 400.0 kHz spot-on, but the wire library must have undergone some changes, Wire.setClock(400000UL) must now be called _after_ Wire.begin(), because the latter sets the clock to the default speed of 100 kHz.

Hello Joop, Excellent presentation with detailed and to the point explanation.

Just when I need this information, great timing! :D

Your Video tutorial is really great and probably the best and most comprehensive I have ever seen. Keep it up! You deserve more subscribers and more thumbs up. What I do not understand is; while calibrating gyro in setup loop there is a delay for 3700 microseconds to simulate the main program loop time (4000 microseconds). What happen if loop time is different in setup loop than that of in the main loop?

mpu 6050 not reponding .. please help

I hope you'll cover YMFC-AL code again for stm32 in new videos. Great explanation, thank you buddy.

Bedankt Joop voor je duidelijke uitleg!

Why are you using FDTI ???....there is an onboard usb input...can't we program it directly from there??

Joop any chance of you putting that code where I can get at it? My eyes are 80 years old and need really thick glasses so I can't read that code, and type it in at the same time. Thanks for a great tutorial. I have just started with STM32 and my LED on pin 13 is wired so LOW is on, weird or what?

Why are you use HWire library instead of wire library, already you get out put in stm32 at same code of Arduino Uno , and it's working fine

Hello how could I improve my mpu6050 code with brushless motor because the signal is stable but when the motor begin turning the mpu signal will be instable!!

Where can i find the given program?

Well, I tried to upload the code to my stm 32 and it didn't work. Please help me

Hi Joop - great video. Keep them coming.

HI and thanks for a great channel! One small point.. That gyro.. I am pretty sure that it uses a 5 V power supply, but on board is a 3V3 LDO and all the IO is actually 3.3 V, so no worries about connecting it to STM32.

What an explanation!!! Thank you man indeed. You said you hope we learned something! Are kidding???

This board is also a great to transition from arduino to STM32CubeIDE, if you can get your hands on an ST-Link. Or the Nucleo 64 is also a great start, since it comes with the ST-Link already attached

Hello man. I hope you can solve my questions. I neeeed it please :))) So it seems to be two ways of adding the board support to the IDE. Yours is one (throught the "arduino SAM boards (32-bits ARM Cortex-M3) by Arduino") and another way is throught the library called "stm32f1xx/gd32f1xx boards by stm32duino". This other way doesn`t require any download except for just pasting an url in the "additional boards manager URL`s" and installing the library with the boards manager. What is exactly the "stm32 for arduino addon" what do you refer by that name? And lastly, in 16:15 you say that by updating the "stm32 for arduino addon" you can now generate 400khz clock because it now uses the hardware i2c library. Does that mean that in the video you were using the software based one and that`s why you needed to add those two resistors? Or is the resistor problem another separate problem? I just want to thank you in advance. Just your channel has gotten me into the microcontroller stuff. I have ordered a lot of stm32, arduinos and sensors hahaha. I have a lot of projects in mind involving an autonomus plane wich i already starting and i already have it maintain a constat airspeed throught a cascade pid system.

Thank You for detailed explanation and theory. Very useful information.

Bravo! Great video with lots of learning points! Thank you.

Nice tutorial, but I missed the part where you explain your obsession for 400 kHz I2C channel. Why 100 kHz are wrong? Without technical justification, the pull up resistors values are too low.

Thanks for the great tutorial. There is one problem though. You have to put setClock AFTER begin. begin will set it to 100 kHz. If you run begin first and THEN set the clock it will work at 400 kHz.

You got a subscriber, good job

Very good and practical information, great presentation.

This was rather helpful, thanks a lot.

Great Videos, keep up the good work. Really helpful !

Great video, many useful information can be learned from it.

Hi, I am constantly getting -1 value from gyro meter. I have validated the connections and the code, but its not working for me. Any help would be greatly appreciated!

With the new bootloader, you can use inbuilt microusb to program it.

Excellent video!! Congrulations

Learned a bunch. Thank you.

Hey joop, perhaps you can increase your font size next time. That makes it a little easyer to read!

Great tutorials on this channel!

did the same things but the reading for all the values is 0 don't know why the mpu is not communicating with the stm board

¿ Porque no haces el video en Español ?

Awesome video!

one of the best videos..thanks

Woaaaa! it's a really nice video. Thank's so much for the easy ti understand explanation

where STM32cubeIDE ?

Great video as usual. Thanks mate.

Great video with good details! Thanks

I did every things as explained and when running the program I receive only zeros and not real values, I the program with Arduino UNO and it working well. what should I DO?

How can I connect 3 MPU?

Have you got any videos in the works? I'd love to see more content from you!

Good review of basics! Thanks. 😃

Hey Joop, did a silly mistake. Taken the variable to store the addition of gyro value as 16 bit. After taking it as a 32bit variable problem got solved. But still my gyro is outputting from -16 to +17 on all the three axis. Should I purchase a new one and try it out?

Excellent video, dankje!

Awesome!!! Thanks so much for your efforts.

thank you ! finally i can solve my problem that i've previously asked ! keep up the good work and nice explanation

is it works at 9600 baudrate

I used the TwoWire library to no avail... for some reason I cannot relocate i2c to sda2 and scl2... I tried everything, even tried to access the circuit's registers... what shall I do?

Mama mia you are talking with very Italian pizza mafia accent ;)

hi joop please help me in the YMFC-AL I want to know the minimum vibration you get after adding tapes mine is between 30-40 of one motor and of 4 motor the vibrations are between 40-70

@Joop, I was able to use the I2C communication with the pins PB6(clock) and PB7(data) but when I try to use the use PB10 and PB11 for I2C it is not working. Have gone through the internet and manual to my best but found nothing useful. I was able to connect the gyro l3g4200d and accelerometer ADXL345 on the same bus line of (I2C1 -> PB6, PB7) but pulling data from these two seem to be on the slower side. I want to connect them each to the separate I2C bus lines (I2C1 -> PB6, PB7 and I2C2 -> PB10, PB11). Any help from you or the community is highly appreciated, Thanks.

Great video! In the gyro the pullups are not 10k but 4k7 and so adding parrallel resistors of 4k7 the pullups becomming half 2k35. But i realy love your channel.

Thanks for the great video!

Great job! Thank you, you made my life a lot easier

I am using an STM32WB30 MCU with MPU6050.If I program it with Arduino IDE, do I have to add the extra 4.7k resistors? Does it still happen or have the drivers been updated?

Where can I download the Arduino_MPU-6050_testfile from. I need to test my breadboard build before I can move on to a PCB videos very much appreciated Joop

I get the erroe: 'Wire" was not declared in this scope, i try many ways but it ditnt work, pls show me what to do

great tutrial. thanks very much

Do you plan on making a "better" custom PCB with the STM32?

Hello would it be possible to have the program for the STM32F103C8T6 because those who accompany the video are for arduino uno. thank you

Can u turn on the CC in the right bottom corner so that we can note down important points? PLEASE!

When I try running "MPU-6050_IMU" I get the following error error:- exit status 1 'LiquidCrystal_I2C' does not name a type Tried looking for library 'LiquidCrystal_I2C' with no luck.Help please

Do you have example project you work here

What is the idea of using STM32 when i can connect Arduino to MPU6050 directly!!?

0:49 -- is this some kind of factory reject? Soldering looks horrible, and board screams for reflowing solder joints and cleaning.

Hi, from where did you took the driver for STM32?

you're the boss @Joop

Great work, thank you.

waht shuldo you do if you have die chines version of the stm and its not working?

Can someone please explain the advantages of why you'd want to use this?

Thank you so much! Love you way to teach.

I really like the stm32's The documentation is excellent. I don't like using HAL to program them. The SPL is good and also their LL functions are awesome if you want to stay closer to the hardware. I wish st32 had all the libraires that the arduino has. Then I would switch.

Thank you very much for this informative video... Please zoom in on the code while explaining it

Great video !

hello joop thanks for your videos ive started programing the stm32 a couple of days ago and i cannot get the i2c clock signal to reach 400khz it does stays fixed at 100khz and ive been using updated wire libraries from the same github developer that you got it, the signal ive measured with an oscilloscope but i think is a library issue becouse it doesnt matter what Wire.setClock value i write it stays fixed at 100khz which is the default value... im asking becouse i dont know what to do at this point... ive reduced pullup resistor with 5kohm resistors as you did, updated arduino/stm32 libraries and full hardware folder and no results.. can you help me? or at least send me on the correct way to solve the problem?

how to choose the pin from some of the i2c pins? does it work for all I2C pins? . And do we need to avoid other I2C pins for other purposes?
