Data send-receive by IIC-bus Hardware: IIC-board with 4 x PCF8574 IC you see a 8bit leds this leds show the value from an other 8574 who has 8 switches as input The 8xswitches from IIC you can see also at the pins PC_0 to PC_7

Gerhard Neumaier will show you :
You can see my hardware: Nucleo F103RB with a IIC-bus application
In the background a printed board "IIC-Trainer" with different IIC ICs like PCF8574a, PCF8591, EEPROM; Real-time-clock In the foreground you see right a own-made printed circuit-board with 4x IC PCF8574
