It can also measure temperature. It is very cheap device but also very powerful. It can measure simultaneously three X, Y and Z channels for accelerometer and gyroscope at the same time with bit resolution.

STM32F103: MPU6050 [I2C] (using Mbed.h)
MPU Have a lot of functions and its not possible to cover all of them in just one tutorial. So in part 1, we will only cover the following In order to initialize the sensor, we need to perform the following actions See below the register content. This register specifies the divider from the gyroscope output rate used to generate the Sample Rate for the MPU This completes the initialization of the MPU and Now we will see How to Read the Data from the sensor and how to convert it in the respective formats.
Let us start with the Acceleration values first. Below is the process to do that Look at the code below. Reading Gyro Data is similar to the Acceleration case. Check below. Or just Download the code below. Hello Controllers tech team Your content was very helpfully and thanks for explain it simple and complete.

We will be using online mbed compiler and will create the program from scratch. Programming part is real easy because most of the work is already done in libraries.
If you want to test this before starting ahead, just download attached binary file onto your Nucleo and open Serial Terminal to Visualize the output. If you are NEW to mbed, please first go through this tutorial briefly. This will help you in getting started with mbed.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Name of each Pin is mentioned in front of that Pin on GY You can google pinout of your MPU Board.
Open mbed Compiler. Sign In. Click on New in the top left corner. From templateselect Empty Program. Enter a program name. Now, right click on that program i. Enter file name main. Click OK. The search for ' mbed '. After some time, a list will appear.
This time search for ' MPU '. Drag the first library named MPU whose author is ' Erik Olieman ' into your program drop onto your program folder i. You may need to change adress of your MPU You need to Change that. In prder to change that, open MPU Change this 0x69 to 0x68 and click on Save.
So Now, your header file is like shown in figure.Vertical jump norms by age
Code is explained in comments. Click on Compile and Download the binary file onto Nucleo Board. In order to visualize the output, you will need to install the a Software that can read from Serial Port.
We will be using Puttymost widely used software. I have attached the.Arduino for STM32 + MPU-6050 == Improve your programming skills!
You can download it from here, or you can from elsewhere. Once downloaded, now run putty. Select ' Serial '. Now, you should be able to see the temperature, Gyrometer and Accelerometer reading on your putty screen.
By ARK Follow. More by the author:. Adding code. Visualize the output Test Run: If you want to test this before starting ahead, just download attached binary file onto your Nucleo and open Serial Terminal to Visualize the output.Besides, a comparison to show timing difference between using and not using DMA is also mentioned.
I also used this library at the first time and found it was quite difficult to get the most updated gyro data for calculation. So, I got the wrong gyro angle all the time. Moreover, I noticed that the code took lots of time to read 14 bytes of data including 6 bytes acceleration, 2 bytes of temperature and 6 bytes of gyronearly 2ms, so there is no chance to get the sample rate at 1ms.
Again, Stdperiph driver V3. Here, we finish setting up the MPU sensor. From now on, the sensor will run with the following configuration:.
This means for example if the sensor is rotated in X axis with maximum angular velocity of degrees per second, the gyro X data will be maximum value of 16bit integer variable: In the other hand, the readout value will be if the angular velocity is degrees per second.
Fire interrupt signal when data is available. Clear interrupt flag whenever the data is completely read out. We have some important points to notice here in order for you to be able to edit the code yourself in the future if you use a another I2C peripheral or different type of sensor with different byte to transfer through DMA:. As you can see from the two tables from STM32F1 reference manual, there are 2 DMA blocks connected to different type of peripherals using different channels.
Then, for reading data, we need to consider channel 7 that is connected to the RX register of I2C1 where all incoming data is stores. Later, if you want to use other peripherals with DMA in your own project, this table can be useful.
Each peripheral inside the STM32 has a boundary address which can be found in Table 3 of the reference manual. And inside that peripheral, there are several registers whose address are inside that peripheral boundary.
After finishing the configuration parts, we move to the reading part. The interrupt routine is as follow:. Now, the reading sequence will be done automatically and store into AccelGyro variable with the minimum time needed.
I have also done a timing test to check how efficient this method could be. Following figures show the timing consume of two method: regular reading and DMA reading.
Fig: regular I2C reading. Fig: DMA supported reading. With the normal way of reading I2C data, CPU is busy for the whole period and cannot do anything else.
