Library for Pololu Maestro Servo Controller

Library docs: https://developer.mbed.org/users/kochansky/code/Maestro/docs/f374c7b60318/classMaestro.html

Example usage:

#include "mbed.h"
#include "Maestro.h"

Maestro maestro(PTC4,PTC3);

int main()
{
    maestro.setBaudRate(9600);

    // limit speed for each servo
    for (uint8_t i = 0; i < 17; i++) {
        maestro.setSpeed(i, 10);
    }

    while (true) {
       // set servo on channel 0 to 90 degrees
       maestro.setServoAngle(0, 90);
       wait(2);

        // set servo on channel 0 to 45 degrees
       maestro.setServoAngle(0, 45);
       wait(2);
    }
}
