# knx # knx
This is a fork of the thelsing/knx stack from Thomas Kunze for and by the OpenKNX Team.
While we did not remove support for any plattform, the testing focus is on RP2040 (main), ESP32 (experimental) and SAMD21(deprecated).
This projects provides a knx-device stack for arduino (ESP8266, ESP32, SAMD21, RP2040, STM32), CC1310 and linux. (more are quite easy to add) This projects provides a knx-device stack for arduino (ESP8266, ESP32, SAMD21, RP2040, STM32), CC1310 and linux. (more are quite easy to add)
It implements most of System-B specification and can be configured with ETS. It implements most of System-B specification and can be configured with ETS.
The necessary knxprod-files can be generated with the [Kaenx-Creator](https://github.com/OpenKNX/Kaenx-Creator) tool. The necessary knxprod-files can be generated with the [Kaenx-Creator](https://github.com/OpenKNX/Kaenx-Creator) tool.
For ESP8266 and ESP32 [WifiManager](https://github.com/tzapu/WiFiManager) is used to configure wifi.
Don't forget to reset ESP8266 manually (disconnect power) after flashing. The reboot doen't work during configuration with ETS otherwise. ## Usage
See the examples for basic usage options
Generated documentation can be found [here](https://knx.readthedocs.io/en/latest/).
## Stack configuration possibilities ## Changelog
Specify prog button GPIO other then `GPIO0`: ### V2.1.0 - 2024-07-03
```C++ - complete rework of the TPUart DataLinkLayer with support interrupt-based handling and optimized queue handling
knx.buttonPin(3); // Use GPIO3 Pin - added DMA support for RP2040 platform
``` - fix some issues with continous integration causing github actions to fail
- added rp2040 plattform to knx-demo example
- added bool GroupObject::valueCompare method for only sending the value when it has changed
Specify a LED GPIO for programming mode other then the `LED_BUILTIN`: ### V2.0.0 - 2024-02-13
```C++ - first OpenKNX version
knx.ledPin(5);
```
Use a custom function instead of a LED connected to GPIO to indicate the programming mode:
```C++
#include <Arduino.h>
#include <Adafruit_NeoPixel.h>
#include <knx.h>
// create a pixel strand with 1 pixel on PIN_NEOPIXEL
Adafruit_NeoPixel pixels(1, PIN_NEOPIXEL);
void progLedOff()
{
pixels.clear();
pixels.show();
}
void progLedOn()
{
pixels.setPixelColor(0, pixels.Color(20, 0, 0));
pixels.show();
}
void main ()
{
knx.setProgLedOffCallback(progLedOff);
knx.setProgLedOnCallback(progLedOn);
[...]
}
```
More configuration options can be found in the examples.
