74ls octal d-type flip-flop datasheet – usbekits
It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand. 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. The term counter limit datasheer to the maximum value the counter runs to e. This lab datasgeet a flip-flop to hold a data value on a bar graph LED.
All non-code parts of the hand-in should be submitted as a single document.

When you record your answers, use the conventions described in the discussion section. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes. Do this by hand using the reference materials. For this lab, you will adapt the string hash program from lab 1. The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. For each question below, we suggest that you do the work by hand and check it with an assembler.
You do not have daatsheet use the assembly program or the simulator.
Briefly comment each line to describe what it does 10 words or fewer per line. 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. Why is it valid or invalid? Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials.
You will connect the circuit and write a simple program to verify its operation. This lab uses the same circuit as Lab 2 part A.
Assume that the output voltage is quiescent i. Embedded Hardware – Part B: It is easy to make small mistakes when you are in a hurry. BUT, we expect both of you to understand and participate in the execution of both labs.
Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.
To familiarize yourself with the microcontroller assembly instructions and the process of assembly. Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. Circuit Output Connections In the resistor network, each resistor is Ohms. Put a brief comment at the beginning which describes the overall function of the code.

For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. Limit your answer to 40 words.
Assume the voltage drop across the LED is 1.
To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! Code files should be submitted separately, per the lab FAQ. Your program shall meet the following requirements: For the questions in part B.
Refer above for details on wiring the circuit. Also, see the course materials repository page.
The first instruction is done as an example. Look carefully at the data sheet!
18-348 Lab #2
Please see the course web page for due dates. Create a similar example using different, non-trivial e. We suggest each of the two students in your lab group be “in charge” of one of the two parts of the lab parts to help divide the work. Assume 74le374 all setup, hold, pulse duration, and propagation times are valid and the dtasheet have settled for these sample points. 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.
Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit.
