Intially the code was properly uploaded to the esp32. But suddenly it stopped. I have tried few methods but nothing helps.
Hi @valkyrie2811 ,
Welcome to the forum..
Could be a few different things..
You don't give allot of information..
If it's Windows then possible that a recent os update changes your drivers..
Look here first, see if it helps..
else need more info..
happened too me a few weeks ago, windows 11 and a esp32cam..
i got "a device attached to the system is not functioning properly" something like it anyways..
downgraded my driver and i was coding again..
good luck.. ~q
I have tried almost everything.
few library functions got updated I have even downgraded them. But it is still showing the same error.
I am using esp32 woom 32ue
following is the code:
#include <Wire.h>
#include <ICM_20948.h>
#include <ESP32Servo.h> // Use the ESP32Servo library
// Define pins
const int buttonPin = 12; // Button connected to GPIO12
const int l298nPin1 = 14; // L298N connected to GPIO14
const int l298nPin2 = 15; // L298N connected to GPIO15
const int servoPin = 13; // Servo connected to GPIO13
// Define state variables
bool buttonPressed = false;
bool actuatorExtended = false;
int servoPosition = 120; // Initial position set to 120 degrees
// Create objects
ICM_20948_I2C myICM; // Use I2C for communication
Servo myServo;
// Function to extend actuator
void extendActuator() {
digitalWrite(l298nPin1, HIGH);
digitalWrite(l298nPin2, LOW);

digitalWrite(l298nPin1, LOW);
}
// Function to retract actuator
void retractActuator() {
digitalWrite(l298nPin1, LOW);
digitalWrite(l298nPin2, HIGH);
delay(5000); // Adjust delay based on actuator speed and travel time
digitalWrite(l298nPin2, LOW);
}

void checkMovement() {

myICM.getAGMT();

Serial.println(myICM.accZ());
// Check for significant movement along the X-axis
if (myICM.accX() > 1.0) {
myServo.write(0); // Move servo to 0 degrees
} else if (myICM.accX() < -1.0) {

}
}

}
Have you tried just uploading a simple sketch?
Like, just a loop that prints "hello" once every 5 seconds or something?

Don't think it's the code..
That error usually means your computer is not seeing the board..
Could also just be a bad usb cable..
Check your device manager, look under Ports and see if it's listed..
~q
i used another cable and even another port but it didnt help.
its listed under ports in device manager
