ELEC 2220 Computer Systems Homework #14 Due: Wednesday, July 7 NOTE: The remaining homework projects for this semester require CodeWarrior version 4.6 or 4.5 (or earlier). The newest download on Freescale’s web site, version 4.7, has eliminated the simulated components that we need for our projects. The CD in the text book contains version 4.5, and that the labs in Broun Hall have either version 4.5 or 4.6. So, if you downloaded version 4.7 or later, you will either need to use a PC in the lab, or install version 4.5 from the text book CD. Code Warrior provides a number of simulated components that can be connected to the simulated microcontroller. In this exercise, you will work with parallel input/output ports by reading the states of 8 push buttons, and displaying the number of any depressed button on a seven-segment LED display. Read sections 18.2 and 18.3 of the text book, and in particular examine Figure 18-7. A 7- segment LED display is to be connected to Ports A and B of the HCS12. The bits of Port A are to
