A new method i2cRead() is added to the arduino.m file. The adiosrv.ped file is modified accordingly. So, with this add-on, your Arduino Uno can speak in I2C through Simulink. The I2C read functionality can be accessed either from Matlab command window or Simulink.
1) In command window, a sample syntax is
a.i2cRead(hex2dec('5A'), hex2dec('07'))
where '5A' denotes the 7bit device address in hex format 0x5A, and '07' denotes the register address '0x07'.
2) In Simulink, you can find the Arduino I2C read block in the arduino_io_lib. When you put the Arduino I2C Read block into your block diagram, be sure to put the correct device address and register address to the parameter field. Help doc is available for instruction inside this download.

Version Published Release Notes

Changed the serial waiting time longer from 0.0001 to 0.0014 so as to avoid the serial read timeout.

Added a parameter field for register address to make this block more general.
