Detailed Description

Class to control a servo on any pin, without using pwm


 // Keep sweeping servo from left to right
 #include "mbed.h"
 #include "Servo.h"

 Servo Servo1(p20);


 while(1) {
     for (int pos = 1000; pos < 2000; pos += 25) {
     for (int pos = 2000; pos > 1000; pos -= 25) {

Constructor & Destructor Documentation

SoftwarePWM::SoftwarePWM ( PinName  Pin)

Create a new SoftwarePWM object on any mbed pin

PinPin on mbed to connect PWM device to

Definition at line 4 of file SoftwarePWM.cpp.

Member Function Documentation

Disable the PWM. After disabling the PWM won't get any signal anymore

Definition at line 35 of file SoftwarePWM.cpp.

void SoftwarePWM::Enable ( int  StartPos,
int  Period 

Enable the PWM. Without enabling the PWM won't be running. Startposition and period both in us.

StartPosThe position of the PWM to start (us)
PeriodThe time between every pulse. 20000 us = 50 Hz(standard) (us)

Definition at line 24 of file SoftwarePWM.cpp.

void SoftwarePWM::SetPosition ( int  NewPos)

Change the position of the PWM. Position in us

NewPosThe new value of the PWM position (us)
