INTRODUCTION
The goal of this application note is to present a useful example of communication using the I2C peripheral of the ST7. The ST7 microcontroller is used as a slave and can communicate with any master. This slave, through the I2C interface, receives data bytes from the master implementing error management and returns them. This application has been realized with a ST72264,7-bit, general call and 10-bit addressing mode.
