Servo test code you can try with the ESC. Send a 0, wait a couple of seconds, then send a 90 to see if the ESC arms (or what ever arming sequence is used with the ESC).

Code: [Select]

// zoomkat 10-22-11 serial servo test
// type servo position 0 to 180 in serial monitor
// or for writeMicroseconds, use a value like 1500
// for IDE 0022 and later
// Powering a servo from the arduino usually *DOES NOT WORK*.

String readString;
#include <Servo.h>
Servo myservo;  // create servo object to control a servo

void setup() {
  Serial.begin(9600);
  myservo.writeMicroseconds(1500); //set initial servo position if desired
  myservo.attach(7);  //the pin for the servo control
  Serial.println("servo-test-22-dual-input"); // so I can keep track of what is loaded
}

void loop() {
  while (Serial.available()) {
    char c = Serial.read();  //gets one byte from serial buffer
    readString += c; //makes the string readString
    delay(2);  //slow looping to allow buffer to fill with next character
  }

  if (readString.length() >0) {
    Serial.println(readString);  //so you can see the captured string
    int n = readString.toInt();  //convert readString into a number

    // auto select appropriate value, copied from someone elses code.
    if(n >= 500)
    {
      Serial.print("writing Microseconds: ");
      Serial.println(n);
      myservo.writeMicroseconds(n);
    }
    else
    {   
      Serial.print("writing Angle: ");
      Serial.println(n);
      myservo.write(n);
    }

    readString=""; //empty for next input
  }
}

Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)

If you look under the files tab, (in the link you provided) you can find the manual.

As far as I can see the only arming process required is that you should make a loop lasting a couple of seconds while
writing 0 or 180 using the servoLib (that should correspond to throttle stick set at 0.)





Hi thanks for answer.
The inputs to uC are comming from thumbpotentiometer. Well see to it that the informations input to the servp is of values 0-180 using the thumbpot.

I hope the servolib manages upto 4 diffrent servoes. Thats something Ill have to checkout.

Thanks for sharing this one.

Hi, janeik

Are the codes here suitable for Atmega 2560 to try on it ?



regards.
