UNIVERSITY OF CONNECTICUT Fall 2011 ECE 3411: Microprocessor Application Laboratory Lab 6 Oct. 17 th , 2011, Due to Oct. 24th. 1 Lab 6: PWM (Combined Timer, USART, and ADC) 1. Objectives Further interface the embedded microcontroller resources with peripherals 2. Related lectures and labs (Lectures 2, 3, 4 and Labs 2, 4, 5) Chapter section: 7.11 System Clock Prescaler Chapter section: 13.7.3 Fast PWM Mode 3. Lab assignments: All of the assignments require using the buzzer. For the most efficient program, in all cases you need to configure the pin on your board that drives the buzzer as a PWM producing pin. This saves computation time and program resources as compared to writing code that manually toggles the pin for the buzzer pin at different frequencies. You can change the PWM frequency when you wish to adjust pitch, but can always keep it at a 50% duty waveform. See section 13.7.3: Fast PWM Mode. 1)
