In this chapter, we will look at how the PIC can communicate with different devices, such as another PIC, some extra EEPROM, a terminal device, a Real-Time Clock (RTC), and many others. There are three main methods for communicating with these devices that PICs use and they are

• SPI, Serial Peripheral Interface

• I²C or IIC which stands for Inter-Integrated Circuit

• UART, Universal Asynchronous Receiver/Transmitter system

In this chapter, we will study how we can use the SPI module, within the PIC, to communicate ...
