 		*  Temporary buffers are reused where possible to reduce peak memory usage
 ==== Sensor Calibration ====
-The calibration process for the MPU6050 was implemented in several steps:
+Initial Angle Determination:
+   * Initial angles are calculated from accelerometer data at startup
-	*  Gyroscope Bias Calibration:
+   * These angles initialize the Kalman filter states
-		*  The device is placed in a stationary position at startup
+   * Ensures stable starting point for the filter
-		*  500 gyroscope readings are collected over approximately 5 seconds
-		*  The average value for each axis is calculated and stored as the gyroscope bias
-		*  This bias is then subtracted from all subsequent gyroscope readings
-	*  Accelerometer Calibration:
-		*  A six-position calibration procedure was used (placing the sensor flat on all six sides)
-		*  For each position, 100 readings are averaged to determine the accelerometer response
-		*  A 3x3 calibration matrix is calculated to correct for misalignment and scale errors
-		*  The calibration matrix is applied to all raw accelerometer readings
-	*  Initial Angle Determination:
-		*  Initial angles are calculated from accelerometer data using arctangent functions
-		*  These initial angles are used to initialize the Kalman filter states
-		*  This ensures the filter begins with accurate orientation information
-The calibration parameters are stored in memory and applied continuously during operation. The calibration procedure significantly improved angle estimation accuracy from ±5° to better than ±0.5° in static conditions.
+Automatic Bias Correction:
+   * The Kalman filter continuously estimates gyroscope bias
+   * No manual calibration required
+   * Bias estimation improves over time during operation

-		*  Configured button input for user interaction and calibration trigger
 	*  UART Communication (Lab 1):
