Serial how to's arduino/pololu

Ok i hope some one can help me. What i need to know should be simple.

Im trying to get a pololu Maestro 24ch servo controller to accept serial commands from an arduino nano wired to PS2 wireless controller head. Using pololu's arduino/pololu scriptino example.

Here is the scriptino code that is added to the pololu script screen....

/* This example shows how to control Maestro scripts with an

Arduino. It assumes you have an RC hobby servo connected on

channel 0 of your Maestro, and that you have already used the

Maestro Control Center software to verify that the servo is

powered correctly and moves when you command it to from the

Maestro Control Center software.

Before using this example, you should go to the Serial Settings

tab in the Maestro Control Center and apply these settings:

* Serial mode: UART, fixed baud rate

* Baud rate: 9600

* CRC disabled

Be sure to click "Apply Settings" after making any changes.

It also assumes you have connected your Arduino to your Maestro

appropriately. If you have not done so, please see

https://github.com/pololu/maestro-arduino for more details on how

to make the connection between your Arduino and your Maestro.

Also, the Maestro needs to have the script in the comment

below installed on it. */

/*

# Maestro script for Script.ino Arduino library example.

# Copy into the Script tab of the Maestro Control Center and

# click Apply Settings.

# Don't do anything by default.

repeat

# Subroutine 0

sub alternate_mid_to_high

begin

6000 0 servo

1000 delay

7000 0 servo

1000 delay

repeat

# Subroutine 1

# Expects the delay time to be on the top of the stack

sub alternate_mid_to_low

begin

6000 0 servo

dup delay

5000 0 servo

dup delay

repeat

*/

#include

/* On boards with a hardware serial port available for use, use

that port to communicate with the Maestro. For other boards,

create a SoftwareSerial object using pin 10 to receive (RX) and

pin 11 to transmit (TX). */

#ifdef SERIAL_PORT_HARDWARE_OPEN

#define maestroSerial SERIAL_PORT_HARDWARE_OPEN

#else

#include

SoftwareSerial maestroSerial(10, 11);

#endif

/* Next, create a Maestro object using the serial port.

Uncomment one of MicroMaestro or MiniMaestro below depending

on which one you have. */

MicroMaestro maestro(maestroSerial);

//MiniMaestro maestro(maestroSerial);

void setup()

{

maestroSerial.begin(9600);

}

void loop()

{

/* Subroutine numbers can be found by clicking "View Compiled

Code..." on the Maestro Control Center script tab.

Restart script at subroutine 0. Subroutine 0 constantly

alternates the servo position from the neutral position to the

high end of the range. */

maestro.restartScript(0);

delay(4000);

// Stop the running script.

maestro.stopScript();

/* Restart subroutine 1 with the value 2000 on the stack.

Subroutine 1 constantly alternates the servo position from the

neutral position to the low end of the range. In this case, The

parameter put on to the stack represents how long the delay is

between servo movements.*/

maestro.restartScriptWithParameter(1, 2000);

delay(4000);

}

Now all i need to do I think is do a serialread() function in the void loop to listen for a byte packet and a function call to activate the subroutine once a button has been pressed.

So we are clear i am trying to activate just subroutine 1 "serially". I am not trying to control servos directly using the Arduino just A subroutine. And i know what commands start and stop the subroutine.
