# iot-contact

iot-contact is an IoT device to check if doors and windows are closed or open.
Furthermore roller shutter motors should be controlled.

## Usage

The content of this repository can be build with CMake and Ninja.

```
cmake -Bbuild -GNinja
ninja -C build
```

Exported files related to the printed circuit board (PCB) can be found in the
build folder.

```
tree build/pcb
```

The resulting firmware can be flashed via a ST-LINK debugger / programmer.

```
st-flash --connect-under-reset write build/fw/zephyr/zephyr.bin 0x8000000
```

UART shell output can be retrieved with `picocom`.

```
picocom -b 115200 /dev/ttyACM0
```

Finally the firmware can be erased from the device with the ST-LINK.

```
st-flash --connect-under-reset erase
```
