I2C¶

I2C

I2C, short for Inter-Integrated Circuit, is a serial bus developed by Philips for connecting microcontrollers and external devices. Devices on the I2C bus can communicate via two lines (SDA and SCL). Devices on the I2C bus are divided into master devices and slave devices. The master device is responsible for initiating communication, while the slave device passively receives instructions from the master device. Devices on the I2C bus can be addressed by address, enabling multiple devices to communicate on the same bus.
