Pulse width Modulation with STM8 using Cosmic C and STVD. Pulse Width Modulation (PWM) is a type of analog modulating technique in which the duration or width of the pulse changes in accordance with the time. It is a commonly used technique to produce a continuous pulse signal with a defined frequency and duty cycle. HOW IT WORKS. Servos can go from 0 to 180 degrees depending on the width of the pulse. Basically you need to keep the pulse (+5v) high for particular amount of time. Few are listed below: 1 milliseconds and corresponds to 0 degrees. 1.5 milliseconds and corresponds to 90 degrees. 2 milliseconds and corresponds to 180 degrees.
