kandi X-RAY | i2cdevlib Summary
the i2c device library (i2cdevlib) is a collection of uniform and well-documented classes to provide simple and intuitive interfaces to i2c devices. each device is built to make use of the generic "i2cdev" class, which abstracts the i2c bit- and byte-level communication away from each specific device class, making it easy to keep the device class clean while providing a simple way to modify just one class to port the i2c communication code onto different platforms (arduino, pic, msp430, jennic, simple bit-banging, etc.). device classes are designed to provide complete coverage of all functionality described by each device’s documentation, plus any generic convenience functions that are helpful. the code is written primarily to support the arduino/wiring implementation, but it may be useful in other circumstances. there are multiple i2c/twi implementations selectable in the i2cdev.h header file if the default arduino "wire.h" is not available or preferable for any reason. there are examples in many of the classes that demonstrate basic usage patterns. the i2cdev class is built to be used statically, reducing the memory requirement if you have multiple i2c devices in your project. only one instance of the i2cdev class is required. documentation for each class is created using doxygen-style comments

QUESTION
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.
...ANSWER
Answered 2020-Dec-01 at 23:32It'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.
