Question it is desired to change the speed of a dc motor by, Ask an Expert

Engineering

Question: It is desired to change the speed of a DC motor by dynamically changing its pulse width using a potentiometer connected at bit 0 of PORTB (Figure). Note that the PWM duty cycle is controlled by the potentiometer. Write a PIC18F assembly language program that will input the potentiometer voltage via the PIC18F4321's on-chip A/D converter using interrupts, generate the PWM waveform on the CCP1 pin, and then change the speed of the motor as the potentiometer voltage is varied.
