Read and write to I2C devices connected to Arduino® hardware
Create an Arduino object using
arduino before you use I2C
functions. See Connect to Arduino Hardware for more information.
All functions, except
scanI2CBus, can be used to generate
code using the MATLAB Function block. For more details, see Deploy Arduino Functions to Arduino Hardware Using MATLAB Function Block.
