PWM in PIC Microcontroller PIC18F4550 devices all have two CCP (Capture/Compare/PWM) modules. Each module contains a16-bit register, which can operate as a 16-bit capture register, a 16-bit compare register or a PWM master/slave duty cycle register which is primarily controlled by timers modules.
What is a servo motor?
A servo motor is a rotary actuator that allows precise control of the angular position. Along with the positive and negative terminals, servo motor also has a control terminal which is used to control the angular position of the servo motor.
What is the difference between servo motor sg90 and its function?
Its functions are similar to the commonly used SG90 servo motor. It is sturdier as it uses metallic gears, compared to the SG90 which uses plastic components. It has an operating voltage range of 4.8 V to 7.2 V and has an operating speed of 0.2 s per 60 degrees.
What is pulse width modulation (PWM)?
Pulse width modulation (PWM) is a widely used modulation technique not only in communication systems but also high current driving applications like motor drivers, LED drivers etc. This tutorial explains how to generate pulse width modulation using PIC18F4550.
What is ccccp in a PIC microcontroller?
CCP stands for capture/compare and PWM. It is a hardware module inside the PIC microcontroller helps to trigger events based on time. Capture mode allows us a duration based timing of an event. This circuit gives information regarding the current state of a register which constantly changes its value. In this case, it is the timer TMR1 register.
What does ppic18f4550 mean?
PIC18F4550 has a built-in peripheral module called the CCP (Capture/Compare/PWM) module for this purpose. The CCP module in PIC18F4550 supports two independent instances of Capture, Compare and PWM feature.
