🔧 Usage Examples

Milwaukee M18 Comprehensive Diagnostics

from ubdf.hardware.manufacturers.milwaukee import M18Diagnostics

# Initialize M18 diagnostics
m18 = M18Diagnostics(port='COM3')

# Run comprehensive health analysis
health = m18.comprehensive_health_analysis()
print(f"Battery Health Score: {health.overall_score}%")
print(f"Safety Events: {health.safety_events}")
print(f"Discharge Analysis: {health.usage_analytics}")

# Generate professional report
report = m18.generate_health_report()
report.export_pdf("battery_health_report.pdf")

Makita Firmware Recovery

from ubdf.hardware.manufacturers.makita import NEC78K0Flasher

# Initialize flasher
flasher = NEC78K0Flasher(port='COM3')

# Program firmware
result = flasher.program_firmware("firmware.hex")
if result.success:
    print("Firmware programming successful!")
    
# Verify programming
verification = flasher.verify_firmware("firmware.hex")
print(f"Verification: {verification.status}")

Arduino Diagnostic Interface

from ubdf.hardware import ArduinoInterface

# Initialize Arduino interface
arduino = ArduinoInterface(port='COM4')

# Run Makita temperature diagnostics
temp_result = arduino.makita_temperature_diagnostic()
print(f"Battery Temperature: {temp_result.temperature}°C")

# Execute modular diagnostics
diagnostics = arduino.run_comprehensive_diagnostics()
print(f"Diagnostic Results: {diagnostics.summary}")
