Department of Electrical and Computer Engineering
ECE 52 Lab 0

[FIRST WEEK OF CLASS]

  • Lab report due date: None. Your TA will verify that you have completed the required tasks at the end of lab.
Lab Objectives
We will do our hardware labs in pairs in this class (that means TWO is the maximum).
 
The objective of this lab exercise is to introduce the student to the various instruments available in the digital systems design lab as well as to some of the integrated circuit (IC) components used in the actual implementation of logic circuits.
Part-A
Lab tour and equipment demonstrations.
Part-B
Follow your TA's instructions for preparing your breadboard and workstation.

Your TA will also show you where lab goggles are and share with you the lab rules.
Part-C
1. Become familiar with the power supply, oscilloscope, and function generator. Your TA will outline the procedures for safely using each piece of equipment.

2. Setup and measure a DC voltage.

3. Measure an output waveform from the function generator for a variety of frequencies.

4. Wire up one AND gate from the 74LS08 IC and demonstrate its functionality with the switch and LEDs.
NOTE: Your TA will show you how to orient a chip (and LED) and count its pins. Don't forget to wire up power (Vcc) and ground (Gnd) and to use a current limiting resistor on the LED !! (you will ALWAYS use limiting resistors with LEDs to prevent damage to the ICs and (later) FPGAs/PLDs)

[Wiring scheme: Vcc:14, Gnd:7, LED+:3, LED-:Rlimiter-to-Gnd, Sw1+:1, Sw1-:Gnd, Sw2+:2, Sw2-:Gnd, Sw1+:1k-pull-up-to-Vcc, Sw2+:1k-pull-up-to-Vcc.]
