| Generic ESP32 Debugging Prompts | |
| 1. Real-Time Log Monitoring | |
| For debugging, use real-time serial log monitoring. | |
| Start serial capture: | |
| ```bash | |
| PORT=$(ls /dev/cu.usbmodem* /dev/ttyUSB* 2>/dev/null | head -1) | |
| stty -f "$PORT" 115200 raw -echo 2>/dev/null || stty -F "$PORT" 115200 raw -echo | |
| cat "$PORT" >> /tmp/device.log & | |
| Monitor logs: | |
| tail -f /tmp/device.log | |
| Search for errors: | |
| grep -E "ERROR|crash|overflow|panic|assert" /tmp/device.log | |
| Before reproducing issues, clear the log: > /tmp/device.log | |
| ### 2. Button/Action Emulation via Serial | |
| Emulate user actions by sending serial commands. | |
| Find port and send command: | |
| PORT=$(ls /dev/cu.usbmodem* /dev/ttyUSB* 2>/dev/null | head -1) | |
| echo "PRESS" > "$PORT" | |
| Send with parameter: | |
| echo "PRESS:3" > "$PORT" | |
| Stress test: | |
| for i in {1..100}; do | |
| echo "PRESS" > "$PORT" | |
| sleep 2 | |
| done | |
| Combine with tail -f /tmp/device.log in another terminal to watch responses. |
