# Raspberry Pi calendar/temperature monitoring station

For more details see https://fliegendewurst.github.io/raspberry-pi-temperature-monitoring.html

The used OLED display is from [Waveshare](https://www.waveshare.com/wiki/1.5inch_RGB_OLED_Module)

## Quick start

```bash

> nix-shell

> rustup target add arm-unknown-linux-musleabihf

> cargo build --release --target arm-unknown-linux-musleabihf

> scp target/arm-unknown-linux-musleabihf/release/{display_all,display_off,refresh_json,take_measurement,status_check_example} 'pi@raspberrypi:~'

> # on the Pi, create sensors.db and events.json

> ./status_check_example > /run/user/1000/status.json

> patchelf --set-interpreter /lib/ld-musl-armhf.so.1 display_all

> ./display_off on

> ./display_all sensors.db events.json temps

```

### Cross compile from NixOS x86_64

```bash

> nix-build --arg crossSystem '(import ).systems.examples.muslpi' -E 'with import  {}; pkgsCross.muslpi.callPackage ./. { }'

> mkdir /tmp/nixstore

> nix copy --extra-experimental-features nix-command --extra-experimental-features flakes --no-check-sigs --to /tmp/nixstore $(readlink -f result)

> rsync -r --links --info=progress --compress /tmp/nixstore/nix pi@himbeere-null:~/

```

On the Pi:

```bash

> sudo mv nix /

> sudo patchelf --set-interpreter /lib/ld-musl-armhf.so.1 /nix/store/*-raspi-oled-*-infdev-*/bin/*

```

(the blue text seen in the second image is bright enough on the real OLED display)
