Embedded Systems project based on ATmega32 Microcontroller in Embedded Systems Professional track provided by Udacity and egfwd. The project was developed using Eclipse IDE and simulated using Proteus Simulator.
-Traffic lights normally consist of three signals, transmitting meaning to drivers and riders through colors and symbols including arrows and bicycles.
-The system consists of 6 LEDs which are red, yellow, and green for both pedestrians and cars, arranged vertically or horizontally in that order in addition to an on-demand crosswalk button.
-Crosswalk button lets the signal operations know that someone is planning to cross the street, so the light adjusts, giving the pedestrian enough time to get across.
-MCAL drivers which are DIO, TIMERS, and INTERRUPTS, and ECUAL drivers which are LED and BUTTON were implemented from scratch.
-The project is developed using the full static architecture and follows the SOLID principles.
-The system consists of 6 LEDs, a push button, and AVR ATmega32 Microcontroller.
-Cars' traffic lights switches every 5 seconds. Same as for pedestrians' traffic lights but with inverted colors.
-The system is built so that to gurantee pedestrians' safety as they are allowed to cross the road if and only if the cars' traffic is red.
-The project is divided into layers : MCAL, ECUAL, and Application layer.
-a UTILITIES Folder is added to define standard types, common used macros, and microcontroller configurations.
-The image below explains the file structure of the whole project.
