Command-line tool to show a clock on a Luminator display, written in Rust.
At the moment, it's really only my Luminator display (a MAX3000 90 × 7 side sign), but it would be relatively easy to extend to different types of signs. If nothing else, it's a good example of how to use my flipdot crate to do something useful.
The most common "real-world" usage is
./dotclock /dev/ttyUSB0 --address 3
which will attempt communication with an actual sign with address 3 over the specified serial port. You can specify a few options to control the appearance:
-tor--24hourto display a 24-hour representation (14:30) instead of the default 12-hour (2:30 PM)-dor--dayofweekto show the day of the week (e.g. WED 28) after the time instead of the month (FEB 28)
By default it will run indefinitely and use a timer to update every minute, but the -o or --oneshot option will display the time once and exit, suitable for use in a cron job.
For testing purposes, you can pass virtual as the port name to fake communication with a virtual sign instead. This doesn't actually print anything to the console without enabling the RUST_LOG environment variable. Example:
RUST_LOG=flipdot=info ./dotclock virtual -a 3
