Topic 1, 2
I made the change, took it off the website and put it in the Preset section under the +Preset, +Playlist buttons, it was in a good location.
Topic 3, 4
It reloads because it needs the updated information so that it can create the preset correctly with all the information generated from the selected image.
Topic 5
The change has already been made, it just hasn't gone up yet, it's default upload
Topic 6, 7
Fixed
Many bad quality analog mics are not centered properly at 1.6V, but stuck at 0V or stuck at 3.3V in silence. The bandpass filter removes DC offsets and improve signal quality.
* debug messages added to different initializers
* SPH0654::initialize() was having a wrong signature: uint8 instead of int8.
C++ can be a real bastard ;-)
* improves robustness of the Matrix effect, by dynamically adjusting the "reference color" used to identify "falling code" head pixels.
* a bit faster, as I've removed the need to scan all pixels a second time for "black screen" detection.
Its still not perfect, and the main loop could be simplified a lot by leveraging on the fact that all changes actually happen in the top row, and "falling" is actually just moving everything down by one pixel.
Update ES8388Source::initialize and ES7243::initialize method signatures to match I2SSource::initialize so that when initialize is called on a AudioSource pointer the child class's method is used.
To make it better readable and prevent copy&paste errors, all needed flags can be referenced from the "esp32" buildenv:
${esp32.AR_build_flags}
${esp32.AR_lib_deps}
* remove "not supported" warning on -S2
* minor tweaking of beat detector
* optimized parameters for arduinoFFT
* fixed a few implicit "double" promotions
* minor UDP protocol optimizations
* small optimization for fft task create / suspend
* completely remove analogmic settings for -S3/-S2/-C3 where analog is not supported
changes were already tested extensively in the MM fork.
this is a band-aid fix for random crashes when switching between presets with multiple segments - crossfade disabled.
!! adding type initializers fixed it for me on -S3, however I still see (less frequent) crashes on esp32, due to heap corruption.
It took me hours to get a meaningful stackdump:
assert failed: heap_caps_free heap_caps.c:360 (heap != NULL && "free() target pointer is outside heap areas")
