kandi X-RAY | MPU6050 Summary

MPU6050 is a C++ library typically used in Internet of Things (IoT), Arduino applications. MPU6050 has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

basic mpu-6050 arduino sketch of sensor function. for a discussion of performance on various microcontroller platforms, uses and limitations of the mpu-6050 see ![here.] i have written a report from the june 11-12, 2014 ![invensense developers conference.] this sketch demonstrates mpu-6050 basic functionality including initialization, accelerometer and gyro calibration, sleep mode functionality as well as parameterizing the register addresses. added display functions to allow display to on-breadboard monitor. no dmp use. we just want to get out the accelerations, temperature, and gyro readings. runs on 3.3v 8 mhz pro mini and teensy 3.1. added quaternion filter based on madgwick’s open-source sensor fusion algorithms. the mpu-6050 lacks a magnetic vector for absolute orientation estimation as is possible with the mpu-9150 or lsm9ds0. this algorithm allows estimation of quaternions and relative orientation, allowing output of yaw, pitch, and roll which is subject to yaw drift due to gyro bias drift. despite the inclusion of a gyro bias drift correction component to the sensor fusion algorithm, yaw drift is about half a degree per minute or less, which is not too bad. in principle, yaw should not be possible to estimate with only a single absolute reference (gravity down), yet this algorithm does a good job of estimating relative yaw with good stability over short time

            I think you've done this right. the MPU6050 has a slave I2C bus that is used to connect the compass. You have wired the setup accordingly.

            You need to configure the MPU correctly, but then it will talk to the compass without the Arduino even knowing of that. You can talk to the HMC, but only trough the MPU with special commands. The device scan will not show the HMC, since it is not directly visible from the Arduino. In this setup, you can't use the magnetometer code you show here. You need to use the MPU6050 binding and configure it for a slave compass (I do not know whether any Arduino MPU6050 library supports this feature, though.)

            Kalman filtering IMU noise c#
            Asked 2022-Jan-09 at 19:43

            I have the following problem. I would like to remove the noise from an IMU sensor. My clue would be a Kalman filter. In the Arduino IDE you could easily implement one via library. Now I would like to solve this by C# directly on the computer but I can't find a library on .NET 4 that works. I tried it with NugetPackages : MathNet. and Emgu.CV. Do you have alternatives that work on .NET 4.0 or do they even work, and if they do, does anyone have a good example? Have a nice day :)

            Need help resolving Arduino Code error [-Woverflow] in gimbal code. I am not sure how to resolve or if to disable yaw
            Asked 2020-Dec-01 at 23:32

            This code is found on how to mechatronics (not mine, https://howtomechatronics.com/projects/diy-arduino-gimbal-self-stabilizing-platform/). I am working on an Arduino gimbal and am using this code. It brings up an error, which I will paste at the bottom. I searched this sort of error and it seems it is because it has an output that is negative but is not defined to come out as negative or may be too large. I am not quite sure what to change or how to change this in order to function. I also have a problem with the yaw motor, which I believe may be fried because my brother connected it to a 12V battery and is only supposed to be 5V. I am sure I can disable the yaw (although not sure if this would solve the other issue) but I don't know which lines to code out in order to do so.

            It's a warning for an int overflow in the MPU6050 library code, not in your code.

            On Github, an issue was raised about this some time ago, which also has the fix in the same posting.

            Another solution suggested in the comments there to get rid of this warning is to simply change the "16384" to "16384L" in the library code.

            Note that i2cdevlib has 247 open issues; I don't think the owner will fix this particular problem any time soon.

            To make the y-axis in ascending order I think you have to make the ys float values instead of string values: ys.append(float(accel_data['x'])) To round the numbers in the y-axis to 5 significant digits you can check the answer to this question: Matplotlib: Specify format of floats for tick labels.

            I have an arduino program that runs a servo when it's at an odd angle, but after five seconds if still at that odd angle set it as the new center. the problem is that for some reason when I'm setting the angles of the current rotation to be the new center, the values get mixed up.

            float stablePos[1]; is an array of one element; the only valid index is stablePos[0]. By accessing stablePos[1], your program exhibits undefined behavior. Same with rot.

            Asked 2020-Jun-20 at 16:46

            during compilation I get a 'multiple definition' error and when I add 'extern' keywords in my hpp file, I get other errors. main.cpp

            ANSWER

            Answered 2020-Jun-20 at 16:46

            So you include MPU.hpp twice, once from main and once from MPU.cpp. If you define externally linked symbols in MPU.hpp, you will get multiple definition errors when linking. The mutable variable int adresse=0x68 is an example of an external variable.

            With each source file including this header file, adresse will be defined. To circumvent that, you need to make sure that you only define it once. What you need to do, is to put the definition in the source file.

            extern is used for exactly this. But you should only declare the variable (not define/initialize it) for each translation unit. If you do extern int adresse=0x68, you still define the variable in each translation unit.

            Correct thing, if you want to have it mutable, to do is set extern int adresse in the header, and then in one source file, you set adresse=0x68 (probably MCU.cpp in your case).

            But adresse looks suspicously non-mutable. If you mark it as const: const int adresse=0x68, adresse will have internal linkage, and can stay in the header.

            So mark any constants in the headers as const and mark variables shared between multiple source files as external. If the variables is only needed in one source file, remove it completely from the header file, and put it into the source file.

            Your timer_start expects an actual function as its first parameter, not the value returned by a call to that function (as will be the case with your included ()).
