9. Debugging & Common Issues

| Symptom | Likely cause | Fix | |---------|--------------|-----| | No I²C ACK | Wrong address or pull-ups | Check ADDR pin (float = 0x58) | | Pins always low | LED mode enabled without PWM | Set config register 0x12–0x13 to 0 | | Interrupt not firing | INT pin floating | Add 10k pull-up to VDD | | Dimming not smooth | Wrong PWM register sequence | Use fade-in (0x20–0x23) then fade-out (0x24–0x27) | highway09a ic datasheet
