Communication takes place from the master (PIC) to the individual selected slave only as shown in this illustration, the master sends data to the slave address 2 only.One resistor from the SCL line to the 5V line and another from the SDA line to the 5V line.For example projects. (with Master I2C module) is the same, and this code should work on most chips with minor modifications for different compilers.Communication via I 2 C is more complex than with a USART or SPI communication.
