I2C Devices
Read and write to I2C devices connected to Arduino®hardware
Create an Arduino object usingarduino
before you use I2C functions. SeeConnect to Arduino Hardwarefor more information.
Note
All functions, exceptscanI2CBus
, can be used to generate code using the MATLAB Function block. For more details, seeDeploy Arduino Functions to Arduino Hardware Using MATLAB Function Block.
