OpenBeken Flag 13: How to View Real-Time GPIO States for Unconfigured Pins?

The discussion centers on the OpenBeken Flag 13 feature, which enables real-time viewing of GPIO pin logic levels for unconfigured pins via HTTP, facilitating button identification without GPIO tracing. The original issue was that the PIN States display was capped at pin P28, limiting visibility for pins like P08 and P12 used as buttons on a TXW camera. Contributors identified that the limitation stemmed from platform-specific constraints, particularly on BK7231N devices, and suggested implementing platform-aware logic to extend the pin state reporting. Code references and commits were shared to address this, including replacing hardcoded pin limits with the PLATFORM_GPIO_MAX constant. Testing and pull requests were proposed to validate these changes. The solution involves modifying the HTTP server code to dynamically handle GPIO pin counts per platform, thereby restoring full visibility of all GPIO states for unconfigured pins in real time.
