EE 322 Lab 6

• Serial Communications
• Due 2/26/08
• Include your Design in your Report

2
Lab 6 Assignment Objective

• Demonstrate proficiency in SDK 51 communications
  with a PC both directions

3
Deliverable outcomes

• Send a welcome message to the PC when the SDK 51
  starts up.
• Echo each lower case character sent from the PC
  back to the PC as an upper case letter
• Any other letters sent to the SDK board will be
  echoed unchanged

4
Prelab

• Design and flow chart (no code) a C program
  that meets the above objectives.

5
Steps

• Code your program using the Franklin compiler
• Include your flow charts in your report
• Simulate your code to verify its functionality
• Program an 89C51 chip and verify that your code
  operates the SDK 51 board properly
• You will need to use
• Franklin ProView 32 for the C compiler and
  simulator
• SuperPro 2000 to program the 89C51 chips
• HyperTerminal on the PC
• SDK 51 board
• Include the SDK board number, the 89C51 chip
  number, and power supply number, and the PC
  workstation number you used for your lab.
• That way I can track any problems that develop
• Good practice to include in your report, the
  devices and serial numbers you used for your
  experiment.

Chip Safety (safety of the chips not you)

• Always wear the provided ground strap.
• Always maintain contact between things you touch
  and the conductive pad.
• Leave the chips plugged into the provided carrier
  sockets, this will greatly reduce pin bending and
  breakage
• Never move chips station to station without being
  plugged into conductive foam or the SDK 51 board
• When you move around always ground your body
  before setting anything on the conductive pad.
