Die Software ist derzeit noch rudimentär gehalten. Die Temperatur wird perodisch ausgelesen und die Heizmatte entsprechend der Zieltemperatur an- oder ausgeschaltet. Über Interrupts wird auf drei Drucktaster reagiert. Dadurch können (derzeit) die Zieltemperatur eingestellt sowie die Heizungsregelung (de)aktiviert werden.

### Verwendete Bibliotheken
|
||||
Für die Ansteuerung des LCD wird `rpi-pico-i2c-lcd` von _T-622_ ([Github](https://github.com/t-622/rpi-pico-i2c-lcd)) verwendet, das wiederum auf `python_lcd` von _dhylands_ ([Github](https://github.com/dhylands/python_lcd)) basiert. Letzteres steht unter der MIT-Lizenz. `rpi-pico-i2c-lcd` ist ohne Lizenzangabe. Die entspechenden Dateien liegen der Einfachheit halber im `lib` Unterverzeichnis.
|
||||
Die C++-Implementierung, die bei Bedarf weiterentwickelt wird, verwendet zur Ansteuerung des Temperatursensors die `pico-onewire` Bibliothek von Adam Boardman ([Github](https://github.com/adamboardman/pico-onewire)).
|
||||
|
||||
_Hinweis_: Die ältere Python-Implementierung ist zu Dokumentationszwecken noch im Unterverzeichnis "micropython" zu finden. Wahrscheinlich wird diese nicht mehr weiterentwickelt.

|

|

### Installation
|
||||
Am einfachsten ist es, mittels [Thonny](https://thonny.org/) die Datei `main.py` sowie den `lib`-Ordner ins Hauptverzichnis des Picos zu kopieren. Auf dem Pico muss natürlich MicroPython installiert sein. Fertig.
|
||||
Zunächst wird das Repository geklont sowie die Submodules initialisiert:
|
||||
```
|
||||
$ git clone https://git.rustysoft.de/martin/gbmanager.git
|
||||
$ cd gbmanager
|
||||
$ git submodule init
|
||||
$ git submodule update
|
||||
```
|
||||
|
||||
Mit den folgenden Kommandos wird die Firmware compiliert:
|
||||
```
|
||||
$ mkdir build && cd build
|
||||
$ cmake -DCMAKE_BUILD_TYPE=Release ..
|
||||
$ make
|
||||
```
|
||||
Im src-Unterverzeichnis (des build-Verzeichnisses!) ist nun UF2-Datei `gbmanager.uf2` vorhanden. Diese muss nun nur noch auf den Pico kopiert werden.

Das Gerät wird über ein microUSB-Kabel mit einem 5V Netzteil, wie man es zum Aufladen von Smartphones verwendet, verbunden. Der Raspberry Pi Pico benötigt sehr wenig Strom, es genügt daher ein "schwaches" Netzteil. Der Euro-Stromstecker kommt an die Steckdose. Damit ist (über ein Relais) das andere Stromkabel, das mit einer Euro-Buchse versehen ist, verbunden. An diese Buchse wiederum kommt die Heizmatte. Das letzte Kabel – in meinem Fall das hellgraue – ist der Temperaturfühler. Dieses muss über eine Bohrung o. ä. in die Gärbox eingeführt werden, so dass eine Temperaturerfassung des Innenraums möglich ist.
|
||||
|
||||
Mit den blauen Tasten stellt man die gewünschte Temperatur ein. Rot schaltet die Heizungssteuerung ein/aus. Ein ">H<" zeigt an, ob gerade geheizt wird.
