How can I optimize power and ensure efficient operation of the VL53L0X sensor and OLED on BeagleBone

hello devs, still based on my project parking assistance system using a BeagleBone Black running Embedded Linux, VL53L0X time of flight distance sensor to detect the distance to nearby objects and a 0.96-inch OLED display to show the distance and warning messages. How can I optimize the system to reduce power consumption and ensure the display and sensor work efficiently, i have ensured correct power sequences, avoided immediate reinitialization after power on. But the `Sensor not responding after power off`

  1. heidi.tech#0
  2. Enthernet Code#0000

    @bosslady0299 Reinitialize the VL53L0X sensor after it powers off to restore functionality.
    Utilize low-power modes and reduce display refresh rates to save power. Update the OLED display only when necessary.
    Add a short delay after powering on the sensor to ensure stability before reinitialization.

    Here’s a modified version

    “`python
    import board
    import busio
    import adafruit_vl53l0x
    from Adafruit_SSD1306 import SSD1306_128_64
    import time
    import subprocess

    def initialize_components():
    i2c = busio.I2C(board.SCL, board.SDA)
    vl53 = adafruit_vl53l0x.VL53L0X(i2c)
    disp = SSD1306_128_64(rst=None)
    disp.begin()
    disp.clear()
    disp.display()
    disp.set_contrast(10)
    return vl53, disp

    def reinitialize_sensor():
    time.sleep(0.1)
    i2c = busio.I2C(board.SCL, board.SDA)
    vl53 = adafruit_vl53l0x.VL53L0X(i2c)
    return vl53

    def display_distance_and_warning(vl53, disp):
    prev_distance = None
    while True:
    distance = vl53.range
    print(f”Distance: {distance} mm”)
    if distance != prev_distance:
    disp.clear()
    if distance < 100: disp.text("Warning: Too Close!", 0, 0, 1) elif distance > 2000:
    disp.text(“Warning: Too Far!”, 0, 0, 1)
    else:
    disp.text(f”Distance: {distance} mm”, 0, 0, 1)
    disp.display()
    prev_distance = distance
    time.sleep(1)

    def main():
    vl53, disp = initialize_components()
    try:
    display_distance_and_warning(vl53, disp)
    except Exception as e:
    print(“Sensor error: “, e)
    vl53 = reinitialize_sensor()
    display_distance_and_warning(vl53, disp)

    if __name__ == “__main__”:
    main()
    “`
