The I²C Protocol

In the last chapter, we looked at using the SPI module of the PIC. This is probably the simplest method of serial communication, as it does not use a protocol. In this chapter, we will look at a process, which does use an industrial protocol, that is termed I²C. We will also study how we can use an I²C expander module and program it, with the 32-bit PIC, to send messages to an LCD.

After reading this chapter, you will be able to use the I²C module of the 32-bit PIC to control an LCD ...
