Clearing EEPROM on XIAO ESP32 C3

Products & Technology
#1

I’ve used this code to write angles in the eeprom of the esp32C3 and update them on button press.

#include <MPU6050_tockn.h>
#include <Wire.h>
#include <EEPROM.h>

MPU6050 mpu6050(Wire);

// EEPROM address to store reference angles
int eeAddressX = 0;
int eeAddressY = sizeof(float);
int eeAddressZ = 2 * sizeof(float);

// Variables to store reference angles
float refAngleX = 0.0;
float refAngleY = 0.0;
float refAngleZ = 0.0;

void setup() {
  Serial.begin(9600);
  Wire.begin();
  mpu6050.begin();
  mpu6050.calcGyroOffsets(true);

  // Read reference angles from EEPROM
  EEPROM.get(eeAddressX, refAngleX);
  EEPROM.get(eeAddressY, refAngleY);
  EEPROM.get(eeAddressZ, refAngleZ);
}

void loop() {
  mpu6050.update();
  Serial.print("angleX : ");
  Serial.print(mpu6050.getAngleX() - refAngleX);
  Serial.print("\tangleY : ");
  Serial.print(mpu6050.getAngleY() - refAngleY);
  Serial.print("\tangleZ : ");
  Serial.println(mpu6050.getAngleZ() - refAngleZ);
  
  // Check if reset button is pressed
  if (digitalRead(3) == LOW) {
    delay(50);  // Debounce delay
    if (digitalRead(3) == LOW) {
      calibrateAngles();  // Reset reference angles to 0.0
    }
  }
}

void saveReferenceAngles() {
  EEPROM.put(eeAddressX, refAngleX);
  EEPROM.put(eeAddressY, refAngleY);
  EEPROM.put(eeAddressZ, refAngleZ);
}

void calibrateAngles() {
  const int readings = 100;
  float sumX = 0.0;
  float sumY = 0.0;
  float sumZ = 0.0;

  for (int i = 0; i < readings; i++) {
    mpu6050.update();
    sumX += mpu6050.getAngleX();
    sumY += mpu6050.getAngleY();
    sumZ += mpu6050.getAngleZ();
    delay(10);
  }

  refAngleX = sumX / readings;
  refAngleY = sumY / readings;
  refAngleZ = sumZ / readings;

  saveReferenceAngles();
}

I want to clear the emulated EEPROM of the esp32 c3. How can I do it? moreover How will I confirm it that the EEPROM is cleared?

thanks.
