ECE 331 Spring 2009 Lab 1: Switch Register Board (SRB) Assembly and Initial Testing Summary: Students will assemble a Switch Register Board (SRB), gaining experience with soldering and PCB assembly. Learning Objectives: Discover basic lab resources and documents Become familiar with lab safety guidelines Become familiar with soldering and PCB assembly Learn how to use the protoboard for building logic circuits Resources and Supplies: Lab and lab safety policies Soldering tutorial Switch Register Board (SRB) Assembly Guide Protoboard Guide SRB parts kit Soldering iron & solder Wire cutters 331 protoboard Power supply Safety glasses (required!) All documents are available on the internet or class website (see Pre-lab below) Important Reminders: Safety glasses are required when performing any non programming task (eg. soldering, wire cutting, wire stripping, etc.). Students without eye protection will not be allowed to work on the lab. Normal eye glasses are permitted, but safety goggles are more much effective and strongly preferred. Pre-lab assignments must be completed before coming to the lab. The pre-lab sheets should be printed, signed/initialed and submitted to the lab TA before beginning the in-lab assignment. Background: The Switch Register Board (SRB) contains a variety of input and output sources that are useful in testing transistor-transistor logic (TTL) digital circuits. For input sources, it has eight two-position switches, which output either a high (5V) or low (0V), a debounced momentary contact switch, and time-base (TTL compatible square wave) outputs for 1 Hz and 1 kHz frequencies, useful as clock pulses or strobe pulses for counters, latches, shift registers, and the like. For output displays it has eight light emitting diodes (LEDs), which turn on when they are connected to a high signal, and two 7-segment hexadecimal displays capable of showing an 8-bit digital value. These input sources (which are actually outputs from the SRB but used as inputs to the circuits you will test) and output displays (which are actually SRB inputs that will indicate the output value of circuits you will test) are all packaged on one printed circuit board (PCB) that you will assemble.

ECE 331 Spring 2009 will provide soldering and PCB construction experience, and the assembled board will be used in future labs to test other circuits you construct. In this lab, each student will build his/her own SRB. The SRB will be used in this lab and in future labs, The SRB inputs (to output displays) and outputs (from switches and clock generators) are all wired to a 25 pin connector on the SRB. This allows the SRB to be plugged, via a cable, into the matched connector on a protoboard where test circuits are assembled. This lab will also introduce you to the protoboard, which you will use to test the assembled SRB and verify it is fully functional. In future labs, you will construct circuits on
