Yep, another [I2cdev.h: No such file or directory] issue

RamDog · August 1, 2021, 4:57am

Greetings,

I recently got rid of Microsoft Cloud storage and moved everything onto my computer. I followed the instructions explicitly for copying the I2Cdev.h folder and it appears in my libraries. When I attempt to compile, the file is not recognized. Following are the operative snippets of code and, following that, the verbose error messages. I am using a Seeeduino XIAO and the error messages do not reveal much.

I appreciate any help that may be presented. I am certain someone else has been here. I understand that some of the included directories may be superfluous but I do not believe they create conflict.

Respectfully - Baran

Even though the Windows file system is not case sensitive, the Arduino IDE's library dependency resolution system is. The correct file name is I2Cdev.h, but the filename you specified via your #include directive is I2cdev.h. Note the different case of the "C" between the two filenames.

So you can fix this problem by changing this line of your sketch:

#include "I2cdev.h"

to this:

#include "I2Cdev.h"

Thank you so much. I woke up this morning and easily compiled another sketch and said "huh?" so I copy and pasted and it worked. I then realized the blindingly obvious mistake I made. I truly appreciate your swift response.

You're welcome. I'm glad to hear it's working now. Enjoy!
