KNX Demo DIY (ESP-IDF 5.x Native)

This is a native ESP-IDF 5.x example project for KNX, based on the Arduino knx-demo-diy example but using the new Esp32IdfPlatform for direct ESP-IDF support.

Features

• Uses the native ESP-IDF APIs (no Arduino layer)
• Demonstrates KNX stack integration on ESP32
• Based on the logic of the Arduino knx-demo-diy.ino example

How to Build

1. Install ESP-IDF 5.x
2. Open a terminal in this directory (examples/knx-demo-esp-idf)
3. Run:

   idf.py set-target esp32
   idf.py build
   idf.py -p /dev/ttyUSB0 flash monitor
   

   (Replace /dev/ttyUSB0 with your ESP32 serial port)

Project Structure

• main.c — Main application file (C++ code, but named .c for ESP-IDF compatibility)
• CMakeLists.txt — ESP-IDF build configuration

Notes

• This project uses the new Esp32IdfPlatform class for native ESP-IDF support.
• You may need to adapt pin numbers and KNX configuration for your hardware.
• The logic is adapted from the Arduino knx-demo-diy.ino example.
