Andrew Russell / Servo

A very simple wrapper around the PWM library.

This is my own wrapper around the PWM library. It handles servos with very long pulse intervals much better. It doesn't HAVE to be used with a servo, but I'm not too sure what else you could use it for. In any case, you're welcome to use it for whatever purpose you want.

Example code is shown below:

#include "mbed.h"
#include "Servo.h"

Servo servo(p26);

int main(void) {
	// .calibrate(pulse interval, minimum pulse width, maximum pulse width)
	servo.calibrate(0.02, 0.05*0.02, 0.10*0.02);
	float val = 0.0;
	while(1) {
		servo.write(val);
		val = val < 1.0 ? val + 0.1 : 0;
		wait(1);
	}
}
