"WebOverview. I2C is a serial, synchronous, half-duplex communication protocol that allows co-existence of multiple masters and slaves on the same bus. The I2C bus consists of two lines: serial data line (SDA) and serial clock (SCL). Both lines require pull-up resistors. With such advantages as simplicity and low manufacturing cost, I2C is mostly ... " - How to start i2c driver in qnx
