The objective of this lab is to design a digital clock using a DS1307 external clock chip. The first step is to interface the clock chip to the microcontroller using an I2 C network. The second step is to design low-level drivers to allow the microcontroller to send and receive data from the DS1307. The next software layer includes functions such as Set Time, Format Time, and Read Time. The highest level is a main program that implements a digital clock using an LED or LCD display. Two, three, or four momentary switches will be used to control the operation of the digital clock.
