I2C (read as I Squared C) bus first introduced by Philips in 1980, because of its simplicity and flexibility the I2C bus has become one of the most important microcontroller bus system used for interfacing various IC-devices with the microcontroller. Each device is built to make use of the generic i2cdev code, which abstracts the I2C bit-level and byte-level communication away from each specific device class, making it easy to keep the device code clean while providing a. SDA is the Serial DAta line, and SCL is the Serial CLock line. Perhaps it is the AT chip? If so, the i2c address should be 0x3f instead of 0x27--- bill. h; The configuration section lets you choose the I/O lines used for SDA and SCL. @EricWang you are correct that it may drop other software, and that will happen because that software is relying on the libc6 2. Since it’s also a licensed trademark, some vendors use another name (such as “Two-Wire Interface”, TWI) for the same bus. Libraries are files written in C or C++ (.
