Wire.requestFrom(SLAVE_ADDRESS, 1) // request byte from slave device Wire.endTransmission() // stop transmitting
Wire.beginTransmission(SLAVE_ADDRESS) // transmit to device #4
#Matlab r2013a arduino serial#
Serial.begin(9600) // start serial for output Wire.begin() // join i2c bus (address optional for master)
However, it can be used in much simpler way, like below:

Main documentation can be find here:īecause of its simplicity in use, price and supporting libraries, you can find many examples how to use it with Arduino. PCF8574 is widely known IO Expander that can be controlled by I2C. So, what could I do with that thing? Of course connect it with Arduino and check how to implement it in Matlab Simulink. It's very useful indeed, because it helps saving pins - instead of 8, you need only 2. It's IO expander that can be controlled by I2C protocole. rtwtypes.How to connect Arduino with IO Expander (PCF8574) using Matlab Simulink?
