 In this repository you will find all of the labs that are required for Robot Kit using MSP432 completion during the IAS0330 course in TalTech.
 
 ## Requirements
-Linux (or WSL), VS Code, openOCD, ARM compilers (arm-none-eabi), Cortex Debug VS Code extension is required to run and debug these labs. Place the whole labs catalogue folder under msp432/simplelink_msp432p4_VERSION/. For additional information go to the [Moodle wiki](https://moodle.taltech.ee/mod/wiki/view.php?id=696448).
