Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. Also, see datashert course materials repository page. Code files should be submitted separately, per the lab FAQ. Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram.

Briefly comment each line to describe what it does 10 words or fewer per line. To familiarize yourself with the microcontroller assembly instructions and the process of assembly.

The term counter limit refers to the maximum value the counter runs to e. Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points.

To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. This lab uses the same circuit as Lab 2 ls34 A.


The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. Look carefully at the data sheet! All non-code parts of the hand-in should be submitted as a single document. Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time.

Please see the course web page for due dates. The first instruction is done as an example. For example, if Q7 is high, and Q6: It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand. It is easy to make small mistakes when you are in a hurry. And, as always, you must do the pre-labs independently.

Datasheeet will connect the circuit and write a simple program to verify its operation. For the questions in part B. Put a brief comment at the beginning which describes the overall function of the code. Do this by hand using the reference materials. Refer above for details on wiring the circuit. For each question below, we suggest that you do the work by hand and check it with an assembler.

Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another. You will be expected to assemble, disassemble, datasheer time code by hand on tests and quizzes.

Circuit Output Connections In the resistor network, each datadheet is Ohms. Embedded Hardware – Part B: Your program shall meet the following requirements: Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup!

Machine code is fetched from memory and the instructions described are executed by the processor. For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.

Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. For this lab, you will adapt the string hash program from lab 1. Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. Assume the voltage drop across the LED is 1.
