Objectives
THE COURSE AIMS TO PROVIDE FUNDAMENTAL KNOWLEDGE FOR THE DESIGN AND DEVELOPMENT OF FIRMWARE FOR EMBEDDED SYSTEMS BASED ON ARM MICROCONTROLLERS AND FOR THE CREATION OF FIRMWARE BASED ON STATE MACHINES USING MODEL-BASED METHODOLOGIES.

THE COURSE COVERS DETAILS ON BOTH THE MAIN SOFTWARE ARCHITECTURES AND THE HARDWARE ARCHITECTURE OF ARM MICROCONTROLLERS, INCLUDING MEMORY ORGANIZATION, BUS SYSTEMS, GPIO STRUCTURE, MAIN PERIPHERALS, COMMUNICATION INTERFACES, AND SERIAL PROTOCOLS.

REGARDING INTERFACING WITH EXTERNAL PERIPHERALS AND SYSTEMS, THE COURSE INTRODUCES THE MOST COMMON SYNCHRONOUS AND ASYNCHRONOUS SERIAL INTERFACES AND PROTOCOLS.

THE COURSE, THEREFORE, PROVIDES AN OVERVIEW OF THE MAIN ENVIRONMENTS FOR MODELING AND VALIDATING EMBEDDED SOFTWARE USING MODEL-BASED APPROACHES.

KNOWLEDGE AND UNDERSTANDING:
ARCHITECTURES OF EMBEDDED SYSTEMS. STRUCTURE OF SOFTWARE FOR AN EMBEDDED SYSTEM. DESIGN AND DEVELOPMENT OF FIRMWARE WITH MODEL-BASED APPROACHES. KNOWLEDGE OF THE MAIN METHODS OF INTERFACING WITH DIGITAL SENSORS AND SERIAL INTERFACES, CONTROL OF DIGITAL ACTUATORS, AND CONTROL OF SERVO MOTORS.

APPLIED KNOWLEDGE AND UNDERSTANDING:
USE OF DEVELOPMENT ENVIRONMENTS FOR EMBEDDED SYSTEMS. DESIGN AND IMPLEMENTATION OF APPLICATIONS ON EMBEDDED SYSTEMS. MODELING FIRMWARE USING MODEL-BASED APPROACHES. COMMUNICATION WITH SENSORS BASED ON SERIAL INTERFACES. CONTROL OF SERVO MOTORS.
