The I2Cdev.h for I2CMaster library from DSSCircuits
This repository contains a working version of I2CDev library that fully supports the I2CMaster library, because the original I2CDev library does not really work with I2CMaster, even though the define I2CDEV_I2CMASTER_LIBRARY is present in the header files.
I created this version because I needed to make the MPU6050 DMP example work with a PJON bus.
For more information, have a look at the respective projects:
