Brushless ESC Calibration Help

I want to make an RC plane, everything was going great with the ESC and the motor until i changed the code and it stopped working normally, I tried calibrating several ways but it just doesn't work, here's an example of my code:

#include <Servo.h>

Servo mot;

void setup() {
  Serial.begin(9600);
  mot.attach(8);

  Serial.println("Waiting 5 seconds untril calibration");
  delay(5000); 

  Serial.println("Sending max throttle");
  mot.writeMicroseconds(2000);
  delay(5000);

  Serial.println("Sending min throttle");
  mot.writeMicroseconds(1000);
  delay(5000);

  Serial.println("ESC calibration done!");
}

void loop() {
  // Idle throttle
  mot.writeMicroseconds(1000);
}

HI, @kokorakabobo_max
Welcome to the forum.

Can you please post your working code?

Sure, this code was used to test the esc and it worked perfectly:

#include <Servo.h>
Servo mot;

void setup() {
  mot.attach(8);
  delay(1000);

  mot.writeMicroseconds(2000);  // Send full throttle (MAX)
  delay(2000);                  // Wait for ESC to detect max (should beep)

  mot.writeMicroseconds(1000);  // Then send min throttle
  delay(3000);                  // ESC should confirm with a few beeps
}

void loop() {
  // Try different throttle values
  mot.writeMicroseconds(1200);
  delay(3000);
  mot.writeMicroseconds(1500);
  delay(3000);
  mot.writeMicroseconds(1800);
  delay(3000);
}

Well the setup codes are different.
Why did you change the setup when you know it works?

Try this...

#include <Servo.h>
Servo mot;

void setup() {
  mot.attach(8);
  delay(1000);

  mot.writeMicroseconds(2000);  // Send full throttle (MAX)
  delay(2000);                  // Wait for ESC to detect max (should beep)

  mot.writeMicroseconds(1000);  // Then send min throttle
  delay(3000);                  // ESC should confirm with a few beeps
}

void loop() {
  // Idle throttle
  mot.writeMicroseconds(1000);
}

I make RC electric planes. What do you think a servo is going to do under throttle control? My smallest planes have 14,000 RPM brushless motors. I never heard of a continuous servo capable of that speed, but go ahead and educate me.

Hi,
Have you tried my code?

Tom.... :smiley: :+1: :coffee: :australia:

No, I have no interest in it.

8

Why, it is just your codes combined.
How do you want us to help you?

I tried your code in post #1 and it compiles clean. What does it do or not do?

Sorry we crossed paths. I am a helper not the op.

No problem.. coffee deficiency....

@kokorakabobo_max This is a pointless exercise. RC planes have propeller rpm's of 14,000 RPM, a servo is only capable of 200 RPM max.
What is needed is a Brushless DC Motor, commonly known as a BLDC. Here is the specs for one of my motors https://amz.cx/3Qi7
If I bought the 1100KV motor and used a battery pack of 3S then the RPM is 1100 X 3 X 3.7 which is 12,210 RPM
