Micro-processor Systems Design
Lab 7 Fall 2021
Purpose:
The purpose of this lab is to familiarize you with writing code using the
A/D functions.
Equipment:
1)
Computer with CCS installed.
2) Multi-meter
3) Oscilloscope.
4)
MSP-EXP430F5529LP LaunchPad
5)
UofA Daughter Board
Data Sheets:
1)
User guide for MSP-EXP430F5529LP LaunchPad
2)
Data sheet for EXP430F5529
3)
MSP 430 Assembly Language Reference Guide
4)
Schematics for UofA Daughter board
Instructions:
As you perform this lab save all your data for the report you will be
writing in the next few weeks.
You will need to have a printout of all scope
wave forms.
Start CCS and load the project created from the lab last week.
Save the project to “
yourinitials_
Lab6.asm” and store it somewhere you can
get to it.
Write the necessary subroutine to set up the Analog to Digital converter such
that a conversion is performed on AN0, AN1, AN2 and the Temperature
sensor.
Save the results of the ADC to RAM in variables named AccX, AccY,
AccZ, and Temperature.
Make sure the values of the analog input from the
accelerometer correspond to the approached RAM variables.
1)
Record the raw data from the A/D converter for the X sensor and place
it on line 1 of the display.
Display the Z sensor in “g” on the fourth
line.
Use the number format “x.x g”.
Make sure use positive and
negative numbers.
2)
Record the raw data from the A/D converter for the Y sensor and place
it on line 2 of the display.
Display the Z sensor in “g” on the fourth
line.
Use the number format “x.x g”.
Make sure use positive and
negative numbers.
3)
Record the raw data from the A/D converter for the Z sensor and place
it on line 3 of the display.
Display the Z sensor in “g” on the fourth
line.
Use the number format “x.x g”.
Make sure use positive and
negative numbers.
4)
Display the Z sensor in “g” on the fourth line.
Use the number format
“x.x g”.
Make sure use positive and negative numbers.
Put all of your screen shots, scope wave forms, data and code into the
appendix of your next report.
