LABORATORY: Laboratory exercises are dedicated to practical usage of Code Composer Studio (CCS) and individual peripheral modules of TMS320F2802x Piccolo processor.
Lab1: CCS First Project, System Initialization, Interrupt, PIE, CPU WDG, Timer0/1/2,
Lab2: Analog to Digital Converter
Lab3: Generate a PWM
Lab4: Generate a HRPWM
Each class lasts 175min laboratory. Laboratory exercises are done in teams of two. Evaluating the laboratory exercises carried out during the classes on the basis of written reports and interviews with the student team.
PROJECTS: The project involves writing and running real-time applications in C according to the assumptions made in the subject project. The project is being carried out in teams of several persons. The project is run with the use of CCS development environment and runtime system hardware real-time hardware in the laboratory. The project must be completed by the end of the semester. Project evaluation is based on working software, and presented a written report. The full CCS environment is also available for students to work at home. A student may participate in the consultation carried out every week (in the 1 hr.). The project allows the consolidation of the knowledge acquired during the lecture and laboratory activities and the acquisition of teamwork skills.
