Seven Segment Display
Usermod that uses the overlay feature to create a configurable seven segment display.
This has only been tested on a single configuration. Colon support is entirely untested.
Installation
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
Settings can be controlled through both the usermod setting page and through MQTT with a raw payload.
Example
Topic <mqttDeviceTopic||mqttGroupTopic>/sevenSeg/perSegment/set
Payload 3
perSegment -- ssLEDPerSegment
The number of individual LEDs per segment. There are 7 segments per digit.
perPeriod -- ssLEDPerPeriod
The number of individual LEDs per period. A ':' has 2x periods.
startIdx -- ssStartLED
Index of the LED that the display starts at. Allows a seven segment display to be in the middle of a string.
timeEnable -- ssTimeEnabled
When true, when displayMask is configured for a time output and no message is set the time will be displayed.
scrollSpd -- ssScrollSpeed
Time, in milliseconds, between message shifts when the length of displayMsg exceeds the length of the displayMask.
displayMask -- ssDisplayMask
This should represent the configuration of the physical display.
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)
Example
HHMMSS
hh:MM:SS
displayMsg -- ssDisplayMessage
Message to be displayed across the display. If the length exceeds the length of the displayMask the message will scroll at scrollSpd. To 'remove' a message or revert back to time, if timeEnabled is true, set the message to '~'.
displayCfg -- ssDisplayConfig
The order that your LEDs are configured. All seven segments in the display need to be wired the same way.
