Topic: motor code error (Read 3 times) previous topic - next topic


FYI For zoomkat, I did already go to that before when it was sent to me before. The code did not work on the first website. I tried it again now and still nothing happened.

Also AWOL, I do sort of understand the loop thing. Its name is also self explanatory. Please help me with this code soon. I'm running out of time


Below is servo test code which you should be able to use to arm your ESC using the serial monitor. Apparently your ESC has beep codes indicating what it is doing. If you don't know the arming sequence, you should contact Parallax for the information.

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() {
  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.print("writing Angle: ");

    readString=""; //empty for next input
Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)


probably the best help received so far. THANK YOU. Finally some descent help. When I type in anything between 0-180, it said writing angle: (*number i typed in*). The ESC was beeping the whole tome until I wrote 1500 then it stopped beeping and when I redid everything, it beeped only 2 or 3 times instead of continuous beeping.  During the whole thing, the motor itself never moved.
here is the tutorial that I was trying to use but continuously failed before:


Doing some searching, you should be able to do the below with the code I posted. This assumes you have proper wiring and power for the motor/ESC.

"For my ESCs I have to output a pulse of 1000 (uS) for a few seconds until it beeps, then I can ramp it up to maximum speed at around 1800."

Im hooking it up to a 9 volts this whole time.  My esc sitll  only beeps when I hook it up to the 9 volt. I tried what you gave me again and it still does not work. Any suggestions?
do I need to program or setup my ESC some special way other than coping and pasting motor or servo codes. I just cant get it to work. The wires are connected the right way (I know this) I need help soon
