MSP430 Timer_A HAL Driver

[cite_start]This repository contains the source code for Part 1 of the final project for the "Embedded Systems Design" course (Democritus University of Thrace, 2025-2026)[cite: 7, 8].

Project Overview

[cite_start]The goal of this project is to develop a Hardware Abstraction Layer (HAL) for the Timer_A module of the MSP430 microcontroller[cite: 29]. [cite_start]This driver allows users to configure and control the timer without needing to directly manipulate hardware registers (such as TACTL, TAR, TACCTLx)[cite: 18, 38].

Features

The HAL library implements the following functionalities through a high-level C API:

• [cite_start]Configuration: Struct-based setup for Clock Source (ACLK, SMCLK), Input Divider, and Counting Mode (Up, Continuous, etc.)[cite: 32, 34].
• [cite_start]Control: Functions to Start and Stop the timer execution[cite: 35].
• [cite_start]Counter Management: Read and Reset the current timer value (TAR)[cite: 36].
• [cite_start]PWM Generation: Dedicated function to easily configure Pulse Width Modulation signals by setting Period and Duty Cycle[cite: 37].

File Structure

• [cite_start]timerA_HAL_23.h: Header file containing the configuration structs, enums, and function prototypes[cite: 43].
• [cite_start]timerA_HAL_23.c: Source file with the implementation of the driver and register manipulation logic[cite: 43].
• [cite_start]timerA_main_23.c: Demonstration application showing usage examples (Timer counting & PWM output)[cite: 45].

Development Environment

• [cite_start]Microcontroller: TI MSP430 (Family x1xx)[cite: 14, 30].
• [cite_start]IDE: IAR Embedded Workbench[cite: 9].
