# Word Clock Usermod V2
This usermod can be used to drive a wordclock with a 11x10 pixel matrix with WLED. There are also 4 additional dots for the minutes.
The visualisation is desribed in 4 mask with LED numbers (single dots for minutes, minutes, hours and "clock/Uhr").
There are 2 parameters to chnage the behaviour:
active: enable/disable usermod
diplayItIs: enable/disable display of "Es ist" on the clock.
## Installation
Copy and update the example `platformio_override.ini.sample`
from the Rotary Encoder UI usermode folder to the root directory of your particular build.
This file should be placed in the same directory as `platformio.ini`.
### Define Your Options
* `USERMOD_WORDCLOCK` - define this to have this the Auto Save usermod included wled00\usermods_list.cpp
### PlatformIO requirements
No special requirements.
## Change Log

* addToConfig() can be used to add custom persistent settings to the cfg.json file in the "um" (usermod) object.
* It will be called by WLED when settings are actually saved (for example, LED settings are saved)
* If you want to force saving the current state, use serializeConfig() in your loop().
*
* CAUTION: serializeConfig() will initiate a filesystem write operation.
* It might cause the LEDs to stutter and will cause flash wear if called too often.
* Use it sparingly and always in the loop, never in network callbacks!
*
* addToConfig() will make your settings editable through the Usermod Settings page automatically.
*
* Usermod Settings Overview:
* - Numeric values are treated as floats in the browser.
* - If the numeric value entered into the browser contains a decimal point, it will be parsed as a C float
* before being returned to the Usermod. The float data type has only 6-7 decimal digits of precision, and
* doubles are not supported, numbers will be rounded to the nearest float value when being parsed.
* The range accepted by the input field is +/- 1.175494351e-38 to +/- 3.402823466e+38.
* - If the numeric value entered into the browser doesn't contain a decimal point, it will be parsed as a
* C int32_t (range: -2147483648 to 2147483647) before being returned to the usermod.
* Overflows or underflows are truncated to the max/min value for an int32_t, and again truncated to the type
* used in the Usermod when reading the value from ArduinoJson.
* - Pin values can be treated differently from an integer value by using the key name "pin"
* - "pin" can contain a single or array of integer values
* - On the Usermod Settings page there is simple checking for pin conflicts and warnings for special pins
* - Red color indicates a conflict. Yellow color indicates a pin with a warning (e.g. an input-only pin)
* - Tip: use int8_t to store the pin value in the Usermod, so a -1 value (pin not set) can be used
*
* See usermod_v2_auto_save.h for an example that saves Flash space by reusing ArduinoJson key name strings
*
* If you need a dedicated settings page with custom layout for your Usermod, that takes a lot more work.
* You will have to add the setting to the HTML, xml.cpp and set.cpp manually.
* See the WLED Soundreactive fork (code and wiki) for reference. https://github.com/atuline/WLED
*
* I highly recommend checking out the basics of ArduinoJson serialization and deserialization in order to use custom settings!
