ECE 25 Lab 1 Introduction to equipment, simple logic Introduction NOTE: Be sure to include the name of both partners, PIDs, and table number on the cover of your lab book before you start The goal of this lab is to introduce the equipment you will use in both ECE 25 and ECE 35. This equipment includes power supplies, function generators, oscilloscopes, and digital multimeters. Before you start, you must read over the “Lab Syllabus,” “Lab Write- Up Tips,” and “Equipment Introduction.” These will be helpful references to make your understanding of lab hardware easier. Your lab write-ups should adhere to a standard format outlined in the “Lab Syllabus” and “Lab Write-Up Tips” on the website. To demonstrate how the equipment works, we will use one combinational logic circuit that implements the NAND function as well as a sequential circuit that is a binary counter. The analysis of both types of logic will be covered in detail in lecture. These logic functions are implemented with two types of integrated chips (IC’s). The 2- input NAND is implemented with a 74LS00N chip, while the 4-bit counter is the CD 4516. Their pin outs are below: Quad NAND gate Counter

ECE 25 Lab 1 2 Prelab The prelab for this first lab is making sure you bring a 5x5 quad ruled lab notebook to the first lab. You will also need a combination lock if you wish to store your board in lab which is recommended. For later labs, you will also need a USB key drive to transfer files to the lab computers. You should read all the way through this entire lab so you will have an idea of what you are to be doing. (This is a good general rule for every lab you work on, regardless if there is a prelab or not). Logic Board All labs will use a combination of the programmable logic board shown below and a separate breadboard used to build your circuits. (see: Lab Equipment Introduction) More information about these boards is provided on the Lab Web site. Power the logic board by connecting the USB cable provided with the board to the front USB connector on the lab computer and the other end into the USB connector on the board. The computer will automatically detect the Basys board.

ECE 25 Lab 1 3 Lab Using a DMM (digital multimeter). A digital multimeter can measure the DC and AC voltage and current. We will demonstrate its use by measuring the voltage required to operate the NAND gate chip. The voltage is generally called VCC on datasheets.
