Linux Kernel Driver and MSP430 FR4133 FRAM Temperature System

Project Overview

This repository contains the implementation of Assignment 2, which includes:

1. Linux Kernel Driver development and kernel recompilation

2. MSP430 FR4133 temperature sensing and FRAM data storage

Part 1: Linux Kernel Driver

• Writing a simple Hello World kernel module

• Compiling using Makefile

• Loading and unloading module using insmod / rmmod

• Checking kernel log using dmesg

• Rebuilding Linux kernel with built-in module support

Build Commands

make
sudo insmod hello.ko
dmesg | tail
sudo rmmod hello

Part 2: MSP430 FR4133 Temperature and FRAM

• Reading internal temperature sensor using ADC12

• Storing temperature data into FRAM

• Recovering stored data after power loss

• LED threshold indication for overheating detection

Development Environment

• Code Composer Studio (CCS)

• MSP430 FR4133 LaunchPad
