Esp32 ulp processor

Hello everyone,

I’ve been working on several projects involving the Wireless Stick Lite V3 using the Arduino framework. I’m wondering if there are any examples or documentation available on how to utilize the ESP32 ULP (Ultra-Low-Power) processor with assembly opcodes. My specific goal is to continuously monitor a pin in the background, keeping track of state changes, and implementing a wake-up mechanism for the main processor under certain conditions.

Your insights and guidance would be greatly appreciated.
