 * **Mikrocontroller:** Ein `STM32G431PB`. Dieser ist zwar leistungsstark, bietet aber alle nötigen Peripherien (mehrere UARTs, ADCs, CAN) und ermöglicht ein einheitliches Hardware- und Software-Design.

-    * **Zwei High-Side Ausgänge (+12V):** Realisiert über einen `VND7050AJ`. Perfekt zur Ansteuerung der 12V-Motorventile (`Öffnen`/`Schliessen`). Die `Sense`-Leitung des Treibers wird über einen AD-Wandler ausgelesen, um durch Messung des Motorstroms eine Endlagen-Erkennung ohne physische Endschalter zu realisieren (Motorstrom im Stillstand ≈ 0).

Zusätzlich können die Temperatur und die Versorgungsspannung des Treibers ausgelesen werden.
     * **Zwei Low-Side Ausgänge (0V):** Über N-Kanal-MOSFETs geschaltete Ausgänge. Nutzbar zur Ansteuerung von 12V-LEDs in Tastern oder zum Schalten des Halbleiter-Relais für die Pumpe.
     * **Zwei digitale Eingänge:** Direkte, geschützte Eingänge am Controller zum Anschluss von Tastern oder den kapazitiven NPN-Sensoren.

-.. zephyr:code-sample:: adc_dt
-   :name: Analog-to-Digital Converter (ADC) with devicetree
-   :relevant-api: adc_interface
-
-   Read analog inputs from ADC channels.
-
-Overview
-********
-
-This sample demonstrates how to use the :ref:`ADC driver API <adc_api>`.
-
-Depending on the target board, it reads ADC samples from one or more channels
-and prints the readings on the console. If voltage of the used reference can
-be obtained, the raw readings are converted to millivolts.
-
-The pins of the ADC channels are board-specific. Please refer to the board
-or MCU datasheet for further details.
-
-Building and Running
-********************
-
-The ADC peripheral and pinmux is configured in the board's ``.dts`` file. Make
-sure that the ADC is enabled (``status = "okay";``).
-
-In addition to that, this sample requires an ADC channel specified in the
-``io-channels`` property of the ``zephyr,user`` node. This is usually done with
-a devicetree overlay. The example overlay in the ``boards`` subdirectory for
-the ``nucleo_l073rz`` board can be easily adjusted for other boards.
-
-Configuration of channels (settings like gain, reference, or acquisition time)
-also needs to be specified in devicetree, in ADC controller child nodes. Also
-the ADC resolution and oversampling setting (if used) need to be specified
-there. See :zephyr_file:`boards/nrf52840dk_nrf52840.overlay
-<samples/drivers/adc/adc_dt/boards/nrf52840dk_nrf52840.overlay>` for an example of
-such setup.
-
-Building and Running for ST Nucleo L073RZ
-=========================================
-
-The sample can be built and executed for the
-:zephyr:board:`nucleo_l073rz` as follows:
-
-.. zephyr-app-commands::
-   :zephyr-app: samples/drivers/adc/adc_dt
-   :board: nucleo_l073rz
-   :goals: build flash
-   :compact:
-
-To build for another board, change "nucleo_l073rz" above to that board's name
-and provide a corresponding devicetree overlay.
-
-Sample output
-=============
-
-You should get a similar output as below, repeated every second:
-
-.. code-block:: console
-
-   ADC reading:
-   - ADC_0, channel 7: 36 = 65mV
-
-.. note:: If the ADC is not supported, the output will be an error message.

-# Firmware Node Application
-
-This Zephyr application provides firmware management capabilities for the irrigation system.
-
-**Tested on Zephyr 4.1.99**
-
-## Features
-
-### Step 1: Shell with Reset Command
-- Shell interface with custom "reset" command
-- Warm reboot functionality
-
-### Planned Features
-- MCUboot support with partition manager
-- Firmware version display
-- MCUmgr support for OTA updates
-
-## Building
-
-```bash
-west build -p auto -b weact_stm32g431_core apps/firmware_node -- -DBOARD_FLASH_RUNNER=blackmagicprobe
-```
-
-## Flashing
-
-```bash
-west flash
-```
-
-## Usage
-
-Connect to the device via serial console and use the shell:
-- `reset` - Reboot the system
-- `help` - Show available commands

+# README for the Hello World Zephyr Application
+
+## Overview
+
+This is a minimal Hello World application built using the Zephyr RTOS. The application demonstrates basic logging functionality by printing a message every 5 seconds, including the version number of the application.
+
+## Project Structure
+
+The project consists of the following files:
+
+- `src/main.c`: The entry point of the application that initializes logging and sets up a timer.
+- `include/app_version.h`: Header file that defines the application version.
+- `VERSION`: A text file containing the version number of the application.
+- `prj.conf`: Configuration file for the Zephyr project, specifying necessary options.
+- `CMakeLists.txt`: Build configuration file for CMake.
+- `README.md`: Documentation for the project.
+
+## Building the Application
+
+To build the application, follow these steps:
+
+1. Ensure you have the Zephyr development environment set up.
+2. Navigate to the `apps/gateway` directory.
+3. Run the following command to build the application:
+
+   ```
+   west build -b <your_board> .
+   ```
+
+   Replace `<your_board>` with the appropriate board name.
+
+## Running the Application
+
+After building the application, you can flash it to your board using:
+
+```
+west flash
+```
+
+Once the application is running, you will see log messages printed every 5 seconds, including the version number.
+
+## Version
+
+The version of this application can be found in the `VERSION` file and is also included in the log messages.

-# Firmware Node Application
-
-This Zephyr application provides firmware management capabilities for the irrigation system.
-
-**Tested on Zephyr 4.1.99**
-
-## Features
-
-### Step 1: Shell with Reset Command
-- Shell interface with custom "reset" command
-- Warm reboot functionality
-
-### Planned Features
-- MCUboot support with partition manager
-- Firmware version display
-- MCUmgr support for OTA updates
-
-## Building
-
-```bash
-west build -p auto -b weact_stm32g431_core apps/firmware_node -- -DBOARD_FLASH_RUNNER=blackmagicprobe
-```
-
-## Flashing
-
-```bash
-west flash
-```
-
-## Usage
-
-Connect to the device via serial console and use the shell:
-- `reset` - Reboot the system
-- `help` - Show available commands
