In this chapter, we will continue our investigation into creating a very useful program, that of the Real-Time Clock. In Chapter 9, we looked at simply using the secondary oscillator to drive a 24-hour clock display. We wrote two programs, one for a simple LCD display and the other for a module with four seven-segment displays. In this chapter, we will look at using an external module that can be attached to the PIC32.

After reading this chapter, you will be able to program the DS3231 ...
