Raw Data vs. Parsed Result Comparison
Raw Data: 0x7f 0x7f 0x00 0x80 0x80 0x0f 0x00 0x00 (Bytes: 8)
Raw Data: 0x7f 0x00 0x00 0x80 0x80 0x0f 0x00 0x00 (Bytes: 8)
Changes were observed in the serial output. USB peripheral data was successfully parsed:
Raw Data: 0x7f 0x7f 0x00 0x80 0x80 0x2f 0x00 0x00 (Bytes: 8)
Parsed Result: CENTER + A
[Repeated identical data multiple times, indicating stable button state]

• Successfully achieved: USB gamepad connection and recognition on the Ai-M61-32S development board
• Technical approach: Solder USB female connector via ribbon cable → Flash USB host demo → Automatically recognize HID device
• Key finding: USB peripheral data can be easily parsed with AI-assisted analysis, significantly simplifying the development process
• Data verification: Raw data and parsed results match accurately, with stable response

Test Completed — USB gamepad functions normally, and data parsing is accurate and reliable
