Lab 4 - Abstract
Lab 4 - Abstract
Lab 4 explores a variety of initialization tasks; the largest one being to setup the clocks for the
MSP430.
This lab also starts off with a worksheet where we will answer a number of questions (and write a
little code) that will be used in the upcoming lab procedure.
Lab 4a – Program MSP430 Clocks
We explore the default clock rates for each of MSP430’s three internal clocks; then, set them up
with a set of specified clock rates.
(Extra) Lab 4b – Blink LED with Different Clocks
If you have time, this lab provides an opportunity to explore the Watchdog Timer.
(Extra) Lab 4C – Utilizing Crystals as Clock Sources
Once again, if you have time, this lab gives us a chance to configure our system to use the
external crystal oscillators found on the Launchpad.
