Lab 0 – Stopwatch & Graphical Menu
Objective: Familiarize with the TM4C1294XL LaunchPad, Code Composer Studio, and basic peripheral programming.
Highlights: System clock setup, LCD initialization, timer ISR, button debouncing, and menu navigation.
View Lab 0 →Lab 1 – FreeRTOS Stopwatch
Objective: Move the stopwatch from a bare-metal super-loop into a FreeRTOS application built from scratch.
Highlights: Manual FreeRTOS integration, task creation, queues, periodic scheduling, and RTOS-based stopwatch design.
View Lab 1 →Lab 2 – Multi-Screen Dashboard
Objective: Refactor the Lab 1 stopwatch into a modular multi-screen application with interrupt-driven buttons, joystick navigation, and microphone level monitoring.
Highlights: Multiple source files, binary semaphores, software timers, ADC microphone sampling, and true multitasking across screens.
View Lab 2 →Lab 3 – Snake Game Part 1
Objective: Implement the core architecture for the Snake game: create FreeRTOS tasks for game logic, input handling, and display updates; protect shared LCD access with a mutex; use message queues for inter-task communication; and apply priority tuning plus runtime profiling to observe and optimize real-time behavior.
Highlights: Task creation, mutexes, message queues, priority tuning, and runtime profiling.
Lab 4 – Snake Game Part 2
Objective: Enhance your Snake game with advanced FreeRTOS timing, synchronization, and performance analysis: precise periodic tasks, buffered input, real-time metrics, and robustness.
Highlights: Hardware timer jitter measurement; vTaskDelay vs vTaskDelayUntil comparison; counting semaphore joystick buffer; 10ms chronometer (software timer); wall collisions & game-over animation; stack usage display, optimization & overflow detection.
Lab 5 – Final System Integration
Objective: Integrate all previous modules into a single multitasking system.
Highlights: FreeRTOS task coordination, inter-task communication, performance monitor, and adaptive Snake gameplay.
