import tensorflow as tf
from tensorflow import lite
from tensorflow.keras.preprocessing import image
from tensorflow.keras.applications.mobilenet_v2 import preprocess_input, decode_predictions
import numpy as np

# Load the MobileNetV2 model
model = tf.keras.applications.MobileNetV2(weights="imagenet")

# Load an image for testing
img_path = "test_image.jpg"
img = image.load_img(img_path, target_size=(224, 224))
img_array = image.img_to_array(img)
img_array = np.expand_dims(img_array, axis=0)
img_array = preprocess_input(img_array)

# Classify the image
predictions = model.predict(img_array)

# Print the classification results
decoded_predictions = decode_predictions(predictions, top=1)[0]
print("Predicted class:", decoded_predictions[0][1])
print("Confidence:", decoded_predictions[0][2])

# Create the TensorFlow Lite model
converter = lite.TFLiteConverter.from_keras_model(model)
tflite_model = converter.convert()

# Write the TensorFlow Lite model to a file
with open("model.tflite", "wb") as f:
    f.write(tflite_model)

In this example, we are classifying an image using a MobileNetV2 model trained with TensorFlow Lite. The model is then converted to TensorFlow Lite format for potential deployment on an STM32 microcontroller.

For a real STM32 application, integrating an appropriate sensor using STM32CubeMX or the STM32 HAL library, and adapting TensorFlow Lite for the microcontroller, would be necessary. This process requires expertise in microcontroller programming and hardware knowledge.
