1. MSP430 and STM32
2. The purpose of this lab is to learn new microcontrollers
and get an introductory lesson on using them by replicating some of
there applications that relate to previous microcontrollers. The
microcontrollers vary in that one is faster and uses less power the
STM32 and the other is similar to the ardiuno and is made by Texas
Instruments.

Discussion
The lab was great to introduce new microcontrollers and some of there
applications. The STM32 is seemingly more involved code wise but
overall is a formitable way of implementing tasks like accelormeter
data. The MSP 430 was similar to arduino and was vey user friendly
overall. The only hiccup was using an iphone. Iphones are good for all
non engineering purposes even better than android but when it comes to
engineering applications its the better horse.
