ServoOut Library
Assign the ServoOut object (output pin) a value in microseconds to change the servo pulse. Note that the default range is between 900 and 2100 microseconds.
Library for generating servo pulses using the Ticker class
include the mbed library with this snippet
// ServoOut Class test program

#include "mbed.h"
#include "ServoOut.h"
ServoOut servo1(p21);
ServoOut servo2(p24);
DigitalOut led1(LED1);
int main() {
servo1.pulse_us = 0;
// spin in a main loop. flipper will interrupt it to call flip
while(1) {
for(float cycle=0.0;cycle<2.0*3.14159;cycle+=.003){
//small amplitude sine wave on servo1
servo1 = 300 * sin(cycle) + 1500;
//ramp up the second servo2 channel relative to cycle
servo2 = 1000 + cycle*159; // .001/(2*PI)
wait(.001); //short delay
}
led1 = !led1; //toggle led1 to indicate activity
}//while(1)
