JOEV 0:782435d2cc06 13 * @brief <strong>TWI_Master</strong> is used for interacting with different libraries of I2C sensors, which I wrote.
JOEV 0:782435d2cc06 14 * This library has been inspired by the <a href="https://github.com/adafruit/Adafruit_Sensor">Adafruit Sensor-Library</a>
JOEV 0:782435d2cc06 15 * and the <a href="https://github.com/jrowberg/i2cdevlib/">I2Cdevlib</a> by jrowberg.
JOEV 0:782435d2cc06 16 * \n\n
JOEV 0:782435d2cc06 17 * It is not an I2C driver, since the existing I2C functions are used and new things, such as masking and individual
JOEV 0:782435d2cc06 18 * bit changes, are built in around them.
