Analyze I2C, SPI, UART, and other communication protocols from capture data
Evaluate heat dissipation and identify thermal failure points
Example Output
Analysis Summary
Device: Arduino temperature controller
Symptom: Display shows random values, restarts every ~2 minutes
Root Cause Assessment
- Primary hypothesis: EEPROM corruption or stack overflow (probability: 75%)
- Evidence: Restart pattern consistent with watchdog timer
- Serial log shows memory address 0x8000 accessed repeatedly
- Secondary hypothesis: Power supply noise (probability: 20%)
- Evidence: Restarts coincide with LCD backlight transitions
- Low probability: Thermal issue (probability: 5%)
Diagnostic Steps
- Check EEPROM integrity: Run
avrdude -c usbtiny -p m328p -U eeprom:r:backup.hex:i - Monitor stack via MCUSR register (0x54) for reset flags
- Capture serial output at 9600 baud during restart sequence
- Measure 3.3V rail voltage during LCD updates (expect <100mV ripple)
Recommended Repair
- Reprogram EEPROM to factory defaults
- Add 100µF decoupling capacitor near LCD connector (C43)
- Enable watchdog timeout adjustment (WDT = 2s)
