em_cmu.h not found

[rbrody8]

I am trying to use the MPU6050 library. When i try to upload the IMU_Zero example though, I get a linker error in I2Cdev.h saying certain em device libraries are missing (i.e. em_cmu.h, em_device.h, em_bitband.h, etc.), and I can't seem to find them anywhere in the I2Cdevlib.

To get the libraries to work, I copied the .cpp/.h files from the .zip I downloaded into a subfolder of the directory my sketch is in, and I modified each #include statement accordingly.

Is there something I'm overlooking? Do you have a copy of the missing libraries I could use?

Thanks

I'm guessing those files come from a different library. https://github.com/EnergyMicro/emlib

Yeah I figured as much. Unfortunately, I've already tried using the library you linked to, and that one requires other EM libraries that aren't included (i.e. em_bitband.h, em_device.h, others possibly). All of the libraries for em_device.h that I can find require some kind of device number to be hardcoded in, but I don't know what my device number is.

I'm using an Arduino Uno and a GY-51 MPU6050 breakout, but I don't know what an em device is let alone what the device number of my set up is. I've tried poling around Google, but from what I can tell, it seems like they are a different type of microcontroller, so I'm not sure why I would need to use these libraries with an Arduino device. I could be wrong though, again I'm not really sure what an em device is.

Everywhere I look, most people seem to get their MPU6050 up and running with little/no issues using this library, so I feel like I'm overlooking some simple issue. Can anyone help be out here?

Thanks!

I'm guessing you dropped the entire repo into your Arduino Libraries folder. The header files noted in the error are only for the EFM32 port of the library. For your use case, you should put only the "I2Cdev" and "MPU6050" folders from the /Arduino subfolder on the repo inside your libraries folder

Thanks! I put the wrong I2Cdev folder into my library folder...not too sure how that happened
