MPU6050 not working

[mathislanglais-sudo]

• I installed it by WebInstaller and ArduinoIDE, when I launched the WebServer he indicated that the MPU6050 was not detected.

Target Hardware: ESP32-C3 (SDA: Pin 8, SCL: Pin 7)
Primary Symptom: Serial log error: Ooops, no MPU6050 detected ... Check your wiring! despite the I2C scanner correctly identifying the device at address 0x68.

1. Issue Analysis
   The hardware connection was verified via an I2C scan: [19:43:34] I2C device found at address 0x68.
   The failure originated within the Adafruit_MPU6050 library. Most low-cost MPU6050 modules are "clones" or variants. While they are functional, their internal WHO_AM_I register (ID) does not exactly match the official value expected by the library.
   The library's begin() function performs a strict ID check and returns false if it doesn't find a perfect match, halting the entire initialization process.
2. The Solution (Library Patch)
   To bypass this software lock, I manually modified the library source file to force the initialization regardless of the chip ID.
   File Path: libraries/Adafruit_MPU6050/Adafruit_MPU6050.cpp
   Target Function: bool Adafruit_MPU6050::begin
   The Modification:
   Inside the code block checking the chip_id_reg.read(), I replaced the failure return with a forced success.

// --- ORIGINAL CODE ---
if (chip_id_reg.read() != MPU6050_DEVICE_ID) {
  return false; // Blocks here for clones
}

// --- PATCHED CODE ---
if (chip_id_reg.read() != MPU6050_DEVICE_ID) {
  // return false; // Disabled strict ID check
  return true;    // Force success to continue initialization
}

3. Implementation Details
   I2C Initialization: On the ESP32-C3, the pins must be explicitly defined using Wire.begin(MPU_SDA, MPU_SCL); before calling the library's init function.
   Startup Timing: A delay isn't strictly required if other functions (like SPIFFS or Data Loading) run first, as they provide a natural "warm-up" time for the sensor.
   Address Formatting: Ensured the address is correctly defined as 0x68 (Hex) or 104 (Dec).
4. Final Result
   After re-flashing the ESP32-C3 with the patched library:
   The MPU6050 is successfully initialized.
   The program proceeds to the WiFi connection (WiFi connected successfully).
   The HTTP WebServer and Voltage monitoring are fully operational.
