usermods/seven_segment_display/readme.md
Uses the overlay feature to create a configurable seven segment display.
This has only been tested on a single configuration. Colon support has not been tested.
Add the compile-time option -D USERMOD_SEVEN_SEGMENT to your platformio.ini (or platformio_override.ini) or use #define USERMOD_SEVEN_SEGMENT in my_config.h.
Settings can be controlled via both the usermod setting page and through MQTT with a raw payload.

Payload 3
The number of individual LEDs per segment. 7 segments per digit.
The number of individual LEDs per period. A ':' (colon) has two periods.
Index of the LED the display starts at. Enables a seven segment display to be in the middle of a string.
When true, when displayMask is configured for a time output and no message is set, the time will be displayed.
Time, in milliseconds, between message shifts when the length of displayMsg exceeds the length of the displayMask.
This should represent the configuration of the physical display.
<pre> HH - 0-23. hh - 1-12, kk - 1-24 hours MM or mm - 0-59 minutes SS or ss = 0-59 seconds : for a colon All others for alpha numeric, (will be blank when displaying time) </pre>HHMMSS
hh:MM:SS
Message to be displayed. If the message length exceeds the length of displayMask, the message will scroll at scrollSpd. To 'remove' a message or revert back to time, if timeEnabled is true, set the message to '~'.
The order your LEDs are configured in. All segments in the display need to be wired the same way.
