    • Descriptions

    The project utilized a TI-TM4C1294 Launchpad (ARM-M4 MCU), a LCD touch panel and RTOS to develop a traffic light controller on the LCD panel. The system of operations is simple: the traffic light alternates between green and red light normally. When the user hits the pedestrian crossing button, the green light immediately turns into a yellow light and turns to red eventually. The system is developed using custom defined tasks based on predefined states in the finite state machine.
