-In order to use the LED we need to enable the SPI interface on the Rpi. 
+![PXL_20251001_103957322 MP~2](https://github.com/user-attachments/assets/8bc182df-a93d-4923-b8d8-88b56d1aa441)
-You can enable it by running `sudo raspi-config`, or by manually adding `dtparam=spi=on` to `/boot/firmware/config.txt`.
-Enable PWM ->  add dtoverlay=pwm to /boot/config.txt
-I²C fpr RTC `sudo raspi-config` -> interface -> enable I²C
 
-# Config 
-
-Flags:
-
-`--error` or `-e`: Enters error state. The LED turns red and the hotspot is activated. This state gets called from systemd if the service is in a failure state.
-
-Environment variables:
-
-- `PM3_BIN`: Path to the pm3 binary. Seach in path if not set. Can also be set to the `pm3_mock.sh` for testing.
-- `LOG_LEVEL`: Can be set to either "debug","warn","error","trace" or "info". Defaults to "warn" in production.
-- `HTTP_PORT`: What port to listen on. Defaults to 80.
-- `HOTSPOT_IDS`: A semicolon seperated list of ids to activate the hotspot with e.g. `578B5DF2;c1532b57`.
-- `HOTSPOT_SSID`: Set the hotspot ssid. Defaults to "fwa".
-- `HOTSPOT_PW`: Set the hotspot password. Default to "a9LG2kUVrsRRVUo1". Recommended to change.
-
-Systemd:
-
-The service is run as a systemd service. There are two service `fwa.service` and `fwa-fail.service`. They read their config 
-from a env file located at `/etc/fwa.env`. See example [env file](service/fwa.env).
-
-# Building
-
-Run `make package` to create `.deb` file. [Cross](https://github.com/cross-rs/cross) is used for building the rust code.
