If you are continuously getting same value, that means your configuration is not right. Check the calculation part for for the range you have chosen

Thanks for the contribution man. Really appreciate it... 👍

@@ControllersTech I always say: Left hand help right hand and both wash my face

I didn't tried it. I tried some algorithms to stabilize the gyro, but that didn't worked. I will try it again after few days ( I am out of my workstation right now)

The R/W bit should be 0 for write and 1 for read. But we don't need to worry about the read address. The HAL adds that 1 during the read operation.

@@ControllersTech ok sir, what if now i change the address with 0xD1 will HAL also add automatically too or will it be a problem?

Nope. It only takes care of receive address.

In cubeIDE, you can enable it in Properties-> C/C++ Build -> Settings -> MCUSetting. You will see the checkbox there to enable it.

It doesn't go faster than 1KHz. If you read every 1 ms, that would be 1KHz.

@@ControllersTech hello, but to restrict it to read every 1ms you would need a delay or a timer interrupt. Otherwise it would sample as fast as the while loop goes. That's how I understood it.

Yeah you put a delay of 1 ms in the while loop

@@ControllersTech thanks for the reply, I have 1 just one more question, does it make sense to work with timer interrupts or DMA to get the sampling timing more accurate.

There is no part 2..

You should work on them separately first and then combine the codes. Better focus on LCD alone and when you understand it, then check the MPU6050.

@@ControllersTech Understood. Thx for replying.

Link is in the description and files are in the src and inc folders..

Because that's the address of the slave (mpu6050)

@@ControllersTech yes I know that but I mean while check slave address on arduino we give 0x68 but on stm32 we have to shift 1 bit why is that?

Because Arduino takes 7 bit address. STM needs 8 bits (7 bits + read/write)

@@ControllersTech thank you

Hi sir , i read your comment and i think i get the same error .. Did you buy another GY521 ? and Did it work after that ? Thanks.

@@achoangnguyen8796 Hi, no I did not continue this project. Sorry

Check tha address. Also check the connections. Use 4K7 pull up resistors on the sck and sda lines

In that function we are reading 6 registers starting from the ACCEL_H_REG. If you check the datasheet of the device, you will find out the next 5 registers.

@@ControllersTech Thanks! And one more thing regarding the values of the gyro. I have managed to build the setup but from what I see the generated values doesn't take into consideration the previous value. If for example I move the gyro at a certain angle I can see an instant change in the value but if I keep the senzor in the same position then the next values will start from zero instead of taking into consideration the angle. Did you manage to solve this issue? I know from Arduino implementation that the read values took into account the position of the sensor instead of creating a reference to zero at each new reading. Thanks!

You can define the variable as static.. For eg- Static float angle;

It's already there on my channel search it

It's in project setting -> c/c++ build -> setting -> tool setting -> mcu setting and enable u printf float

Window not?

Right now only acceleration values are usable. I tested some theories and some other methods to calibrate gyro but wasn't successful. They always drift away 🤦‍♂️. I will soon start working on dmp port from arduino. That will definitely stabilize the gyro

@@ControllersTech Any joy with porting DMP to STM32?

There are lot of errors and other things to be taken into consideration while measuring angle. Like I mentioned in the video I'll make another one involving all those things soon. Or you can refer any arduino based code and port it. It should work

@@ControllersTech Thx for answer. I'll try it... again :)

@@ControllersTech you did not do it yet right?

I have to start working on the angle part. I forgot as it was due for a while. The problem is that the error get developed in the gyro as the time passes. There are some algorithms to solve the issue. I'll take a look. If you want to use angular velocity to do so, you can use the formula (w = ∆theta/∆t)

Goto the link in the description.. at the end of the post, there is a download button

yes but you need some application which can do the plotting for you. Then use uart to send the data to the app and it will plot the curve

@@ControllersTech Okay, thanks! I'll give it a try.

@@ControllersTech In fact you have configured the MPU6050 in one of your videos I would like to know how to get a curve from it. If you could make a small video to show how to get a curve of the gyro and acceleration parameters. Thanks

Right click on it and goto declaration

@@ControllersTech ooo okay, can i know where i can find your sample code?, because on your website i cant seem to find it(the one you put on your discription), anyways, thanks for your awesome tutorial, it helped me a lot !!

it's there... at the bottom of the page

@@ControllersTech yup i found it just a second ago, there is a downlaod button. Thank you

I don't think that affects it. That's just to confirm if the device is connected and is responding

@@ControllersTech Hello.Thank you for your great tutorial! I tried a lot but i couldn't receive correct data from MPU6050. I followed everything that you said. Also why do you Define MPU address D0? shouldn't it be 0x68 or 0x69? Regards

What you mean filtered ?

@@ControllersTech I want to filter my pressure, acceleration sensors. Is this something done during coding?

I still don't understand what you mean by filter the acceleration.. But anyway yes you have to do all at the time of coding itself. If your query is more related to sensor, you can check the datasheet. There might be some register which can help you

@@ControllersTech thank you anyway, I couldn't explain myself.
