## Build

The firmware is built for [gokrazy](https://gokrazy.org). Identify the device
for your SD-Card, then run the command below to overwrite it. Ensure that no
partitions are mounted on the card prior to running the command.

```bash
gok --parent_dir ./deployments --instance fermentor overwrite --full <device>
```

## TODO

- hardware: Fix the LCD display contrast by adding a 3v3/5v logic level converter
- firmware: Add a way to control the runtime configuration
  - use nats to control the runtime parameters
