- System Overview: Data from sensors is processed in the studio to build models, which are optimized and deployed to edge devices for inference. - Component Relationships: Data drives model training, studio handles development, deployment enables application.

Implementation Details

Basic Implementation

# Example using DeepCraft's Python API (simplified; actual API may vary)
import deepcraft  # Assuming DeepCraft Python library

# Load sample accelerator project
project = deepcraft.load_accelerator('gesture_recognition')

# Add your data
project.add_data('my_gestures.csv', labels=['wave', 'circle', 'stop'])

# Train model
model = project.train(epochs=50, batch_size=32)

# Optimize for target MCU
optimized_model = model.optimize(target='arm_cortex_m4')

# Deploy (generate C code)
optimized_model.export('gesture_model.c')
- Step-by-Step Setup: 1. Install DeepCraft Studio from the official website. 2. Download a starter accelerator (e.g., gesture recognition). 3. Import your sensor data and labels. 4. Train and deploy the model to hardware. - Code Walkthrough: - Load a pre-configured project, add data, train, optimize for edge, and export code. - Common Pitfalls: - Data format issues: Ensure CSV matches expected columns (e.g., accelerometer data). - Hardware compatibility: Check target MCU support. - Overfitting: Use validation splits in training.
