We suggest each of the two students in dxtasheet lab group be “in charge” of one of the two parts of the lab parts to help divide the work. BUT, we expect both of you to understand and participate in the execution of both labs. And, as always, you must do the pre-labs independently.

Please see the course web page for due dates. Embedded Hardware – Part B: Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.

Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit.

Circuit Output Connections In the resistor network, each resistor is Ohms. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram. When you record your answers, use the conventions described in the discussion section. For example, if Q7 is high, and Q6: Assume that all setup, hold, pulse 74,s374, and propagation times are valid and the outputs have settled for these sample points.

Why is it valid or invalid? Limit your answer to 40 words. Look carefully 74ks374 the data sheet! Assume the voltage drop across the LED is 1. Assume that the output voltage is quiescent i. To familiarize yourself with the microcontroller assembly instructions and the process of assembly. Machine code is fetched from memory and the instructions described are executed by the processor. This ddatasheet performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another.

For each question below, we suggest that you do the work by hand and check it with an assembler. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes.

The first instruction is done as an example. Do this by dagasheet using the reference materials. It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand.

Put a brief comment at the beginning which describes the overall function of the code. Briefly comment each line to describe what it does 10 words or fewer per line. For branch instructions, insert labels 74ls3744 the appropriate locations and use the label values in your disassembled assembly code.

Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time. Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. Create a similar example using different, non-trivial e.

Confirm the operation using the simulator to make sure you got it right, which you need document only by saying “checked with simulator” in your hand-in.

It is easy to make small mistakes when you are in a hurry. Using a checklist is your best defense against this in general, and in particular is extremely helpful for 74,s374 unnecessary point losses when handing in assignments for this course. Paste datashheet copy of the pre-lab portion of the Lab Writeup Checklist datasneet your hand-in materials. The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them.

Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. You MUST follow these procedures or we will not accept your submissions. Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. This lab uses a dqtasheet to hold a data value on a bar graph LED.

You will connect the circuit and datasueet a simple program to verify its operation. For this lab, you will adapt the string hash program from lab 1. This lab uses the same circuit as Lab 2 part A. Refer above for details on wiring the circuit. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results. Your program shall meet the following requirements: For datasheeet questions in part B. You do not have to use the assembly program or the simulator.

For the questions involving the running sum, you may find it faster to compute the sum using a formula for an arithmetic sequence, rather than doing the sum iteratively.

The term counter limit refers to the maximum value the counter runs to e. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials.

Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. All non-code parts of the hand-in should be submitted as a single document. Code files should be submitted separately, per the lab FAQ. Also, see the course materials repository page.
