MATLAB® supports I2C (Inter-Integrated Circuit) interface communication through Instrument Control Toolbox™. I2C is a chip-to-chip interface that supports two-wire communication. Instrument Control Toolbox I2C support lets you open connections with individual chips or on-board I2C sensors. You can then read and write data over these connections.
When characterizing a sensor or verifying the performance of a device or subsystem, you can configure chip settings using I2C while measuring outputs of the board or device with other test and measurement equipment. I2C interface support is available using USB to I2C host adapters from Total Phase and National Instruments®.
Instrument Control Toolbox supports the I2C interface hardware shown below.
