Mini24 with Arduino SelectMultipleTarget

Thanks Patrick. I manage to get SetMultiTarget to work but I run into the same issue as this guy.

Arduino Uno + Mini Maestro 12 problems

I am completely new to Arduinos and using the maestro 12, so sorry if my problem is something stupid. I am controlling 8 of the HS-755 HB servos with the maestro. I am using a 6V, 3000 mAh, 5 cell battery to power the servo controller. The uno is connected to the maestro through the serial pins. I am running the following simple script to move the servos to a basic position and maintaining it: #include <PololuMaestro.h> MicroMaestro maestro(Serial); void setup() { Serial.begin(9600); mae…

Sometimes the servos will go to the desired position and jitter and sometime just jerk but cannot go to the desired position.

let me explain how I wiring my Mini Maestro ,Mega2560 and Servo.

1. Mini maestro-24 connect to usb=> to my PC.
2. Mini maestro-24 get servo power from external power supply DC6V. I am sure that this external power supply has enough power supply to my 4 servos
3. Mega2560 connect to usb=> to my PC.
4. ground is connect from Mega2560=>Maestro-24 and external power supply
5. Maestro-24 RX connect to Meag2560 pin 11 , Maestro-24 TX connect to Meag2560 pin 10
6. 4 units Servo connect to Maestro-24 at pin 0-3
   I monitor the error log while the Arduino is communicating with the maestro, the maestro works perfectly and all the servos go to the desired positions no problem - no errors listed. Do you guys have any idea what the problem is? below is my code.

#include <PololuMaestro.h>
#include <SoftwareSerial.h>
SoftwareSerial maestroSerial(10, 11);
uint16_t BeginArray={4000,4000,4000,4000};
uint16_t EndArray={7000,7000,7000,7000};
//MicroMaestro maestro(maestroSerial);
MiniMaestro maestro(maestroSerial);

void setup()
{
pinMode(10,INPUT); //set rx (or pin 0) as input
pinMode(11, OUTPUT); //set tx (or pin 1) as output
maestroSerial.begin(115200);
maestro.setSpeed(0, 100);
maestro.setAcceleration(0,60);
maestro.setSpeed(1, 100);
maestro.setAcceleration(1,60);
maestro.setSpeed(2, 100);
maestro.setAcceleration(2,60);
maestro.setSpeed(3, 100);
maestro.setAcceleration(3,60);
}

void loop()
{
maestro.setMultiTarget(4,0,BeginArray);
delay(4000);
maestro.setMultiTarget(4,0,EndArray);
delay(4000);
}
