Auto Save

v2 Usermod to automatically save settings to preset number AUTOSAVE_PRESET_NUM after a change to any of:

• brightness
• effect speed
• effect intensity
• mode (effect)
• palette

but it will wait for AUTOSAVE_AFTER_SEC seconds, a "settle" period in case there are other changes (any change will extend the "settle" window).

It will additionally load preset AUTOSAVE_PRESET_NUM at startup during the first loop().

AutoSaveUsermod is standalone, but if FourLineDisplayUsermod is installed, it will notify the user of the saved changes.

Note: I don't love that WLED doesn't respect the brightness of the preset being auto loaded, so the AutoSaveUsermod will set the AUTOSAVE_PRESET_NUM preset in the first loop, so brightness IS honored. This means WLED will effectively ignore Default brightness and Apply N preset at boot when the AutoSaveUsermod is installed.

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_AUTO_SAVE - define this to have this the Auto Save usermod included wled00\usermods_list.cpp
• AUTOSAVE_AFTER_SEC - define the delay time after the settings auto-saving routine should be executed
• AUTOSAVE_PRESET_NUM - define the preset number used by autosave usermod
• USERMOD_AUTO_SAVE_ON_BOOT - define if autosave should be enabled on boot
• USERMOD_FOUR_LINE_DISPLAY - define this to have this the Four Line Display mod included wled00\usermods_list.cpp also tells this usermod that the display is available (see the Four Line Display usermod readme.md for more details)

Example to add in platformio_override: -D USERMOD_AUTO_SAVE -D AUTOSAVE_AFTER_SEC=10 -D AUTOSAVE_PRESET_NUM=100 -D USERMOD_AUTO_SAVE_ON_BOOT=true

You can also configure auto-save parameters using Usermods settings page.

PlatformIO requirements

No special requirements.

Note: the Four Line Display usermod requires the libraries U8g2 and Wire.
