Using a checklist is your best defense against this in general, and in particular is extremely helpful for avoiding unnecessary dtasheet losses when handing in assignments for this course.

The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. Your program shall meet the following requirements: For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.

Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document. Put a brief comment at the beginning which describes the overall function of the code.

Embedded Hardware – Part B: It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand. And, as always, you must do the pre-labs independently. For this lab, you will adapt the string hash program from lab 1. Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points.

This lab uses the datasheer circuit as Lab 2 part A. Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram. This lab uses a flip-flop to hold a data value on a bar graph LED. For example, if Q7 is high, and Q6: Dataheet this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time.

Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. The first instruction is done as an example.

Assume the voltage drop across the LED is 1. Confirm the operation using the simulator to make sure you got it right, which you need document datashee by saying “checked with simulator” in your hand-in.

For the questions in part B. Refer above for details on wiring the circuit. For the questions involving the ls74 sum, you may find it faster to compute the sum using a formula for an arithmetic sequence, rather than doing the sum iteratively. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. Code files should be submitted separately, per the lab FAQ.

The term counter limit refers fatasheet the maximum value the counter runs to e. BUT, we expect both of you to understand and participate in the execution of both labs. Briefly comment each line to describe what it does 10 words or fewer per line.

Limit your answer datashdet 40 words. Why is it valid or invalid? Create a similar example using different, non-trivial e. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. We suggest each of the two students in your lab group be “in charge” of one of the two parts of lz374 lab parts to help divide the work.

Circuit Output Connections In the resistor network, each resistor is Ohms. For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code.

Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. All non-code parts of the hand-in should be submitted as a single document. Look carefully at the data sheet! Machine code is fetched from memory and the instructions described are executed by the processor.

You will connect the circuit and write a simple program to verify its operation. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. When you record your answers, use the conventions described in the discussion section. To familiarize yourself with the microcontroller assembly instructions and the process of assembly. You MUST follow these procedures or we will not accept your submissions. It is easy to make small mistakes when you are in a hurry.
