Seven Segment Display Reloaded

Usermod that uses the overlay feature to create a configurable seven segment display. Optimized for maximum configurability and use with seven segment clocks by parallyze (https://www.instructables.com/member/parallyze/instructables/) Very loosely based on the existing usermod "seven segment display".

Installation

Add the compile-time option -D USERMOD_SSDR to your platformio.ini (or platformio_override.ini) or use #define USERMOD_SSDR in my_config.h.

For the auto brightness option, the usermod SN_Photoresistor has to be installed as well. See SN_Photoresistor/readme.md for instructions.

Settings

All settings can be controlled the usermod setting page. Part of the settings can be controlled through MQTT with a raw payload or through a json request to /json/state.

enabled

Enables/disables this overlay usermod

inverted

Enables the inverted mode in which the background should be enabled and the digits should be black (leds off)

Colon-blinking

Enables the blinking colon(s) if they are defined

enable-auto-brightness

Enables the auto brightness feature. Can be only used with the usermod SN_Photoresistor installed.

auto-brightness-min / auto-brightness-max

The lux value calculated from usermod SN_Photoresistor will be mapped to the values defined here. The mapping is 0 - 1000 lux will be mapped to auto-brightness-min - auto-brightness-max

The mA current protection of WLED will override the calculated value if it is too high.

Display-Mask

Defines the type of the time/date display. For example "H:m" (default)

H - 00-23 hours
h - 01-12 hours
k - 01-24 hours
m - 00-59 minutes
s - 00-59 seconds
d - 01-31 day of month
M - 01-12 month
y - 21 last two positions of year
Y - 2021 year
: for a colon

LED-Numbers

LED-Numbers-Hours
LED-Numbers-Minutes
LED-Numbers-Seconds
LED-Numbers-Colons
LED-Numbers-Day
LED-Numbers-Month
LED-Numbers-Year

See following example for usage.

Example

Example for Leds definition

  <  A  >
/\       /\
F        B
\/       \/
  <  G  >
/\       /\
E        C
\/       \/
  <  D  >

Leds or Range of Leds are seperated by a comma ","

Segments are seperated by a semicolon ";" and are read as A;B;C;D;E;F;G

Digits are seperated by colon ":" -> A;B;C;D;E;F;G:A;B;C;D;E;F;G

Ranges are defined as lower to higher (lower first)

For example, an clock definition for the following clock (https://www.instructables.com/Lazy-7-Quick-Build-Edition/) is

hour "59,46;47-48;50-51;52-53;54-55;57-58;49,56:0,13;1-2;4-5;6-7;8-9;11-12;3,10"
minute "37-38;39-40;42-43;44,31;32-33;35-36;34,41:21-22;23-24;26-27;28,15;16-17;19-20;18,25"

hour "6,7;8,9;11,12;13,0;1,2;4,5;3,10:52,53;54,55;57,58;59,46;47,48;50,51;49,56"
minute "15,28;16,17;19,20;21,22;23,24;26,27;18,25:31,44;32,33;35,36;37,38;39,40;42,43;34,41"

depending on the orientation.

The example detailed:

hour "59,46;47-48;50-51;52-53;54-55;57-58;49,56:0,13;1-2;4-5;6-7;8-9;11-12;3,10"

there are two digits seperated by ":"

59,46;47-48;50-51;52-53;54-55;57-58;49,56
0,13;1-2;4-5;6-7;8-9;11-12;3,10

In the first digit, the segment A consists of the leds number 59 and 46., segment B consists of the leds number 47, 48 and so on

The second digit starts again with segment A and leds 0 and 13, segment B consists of the leds number 1 and 2 and so on

first digit of the hour

Segment A: 59, 46
Segment B: 47, 48
Segment C: 50, 51
Segment D: 52, 53
Segment E: 54, 55
Segment F: 57, 58
Segment G: 49, 56

second digit of the hour

Segment A: 0, 13
Segment B: 1, 2
Segment C: 4, 5
Segment D: 6, 7
Segment E: 8, 9
Segment F: 11, 12
Segment G: 3, 10
