~~ NOTES ~~
|
|
|
|
[use_defaults]
|
|
|
|
For any dicts in this file (config.py), you can add them into the use_defaults
|
|
dict to force the program to use these values over any stored in settings.ini
|
|
that you would have set using the GUI. At runtime, settings.ini is used to update
|
|
the above dicts with custom set values.
|
|
|
|
If you're running a headless RPi, you may want to edit settings in this file, then
|
|
specify to use the dict you wrote, rather than have the program overwrite from
|
|
settings.ini at runtime. You could also run the program with the gui, set the
|
|
settings that you want, then disable the gui and the custom settings will still
|
|
be loaded. Basically it works as you would expect it to.
|
|
|
|
[DEVICE TYPE]
|
|
|
|
Device used to control LED strip.
|
|
|
|
'esp8266' means that you are using an ESP8266 module to control the LED strip
|
|
and commands will be sent to the ESP8266 over WiFi. You can have as many of
|
|
these as your computer is able to handle.
|
|
|
|
'pi' means that you are using a Raspberry Pi as a standalone unit to process
|
|
audio input and control the LED strip directly.
|
|
|
|
'blinkstick' means that a BlinkstickPro is connected to this PC which will be used
|
|
to control the leds connected to it.
|
|
|
|
'fadecandy' means that a fadecandy server is running on your computer and is connected
|
|
via usb to a fadecandy board connected to LEDs
|
|
|
|
'dotstar' creates an APA102-based output device. LMK if you have any success
|
|
getting this to work becuase i have no clue if it will.
|
|
|
|
'stripless' means that the program will run without sending data to a strip.
|
|
Useful for development etc, but doesn't look half as good ;)
|
|
|
|
[REQUIRED CONFIGURATION KEYS]
|
|
|
|
===== 'esp8266'
|
|
"AUTO_DETECT" # Set this true if you're using windows hotspot to connect (see below for more info)
|
|
"MAC_ADDR" # MAC address of the ESP8266. Only used if AUTO_DETECT is True
|
|
"UDP_IP" # IP address of the ESP8266. Must match IP in ws2812_controller.ino
|
|
"UDP_PORT" # Port number used for socket communication between Python and ESP8266
|
|
===== 'pi'
|
|
"LED_PIN" # GPIO pin connected to the LED strip pixels (must support PWM)
|
|
"LED_FREQ_HZ" # LED signal frequency in Hz (usually 800kHz)
|
|
"LED_DMA" # DMA channel used for generating PWM signal (try 5)
|
|
"BRIGHTNESS" # Brightness of LED strip between 0 and 255
|
|
"LED_INVERT" # Set True if using an inverting logic level converter
|
|
===== 'blinkstick'
|
|
No required configuration keys
|
|
===== 'fadecandy'
|
|
"SERVER" # Address of fadecandy server. (usually 'localhost:7890')
|
|
===== 'dotstar'
|
|
No required configuration keys
|
|
===== 'stripless'
|
|
No required configuration keys (heh)
|
|
|
|
[AUTO_DETECT]
|
|
|
|
Set to true if the ip address of the device changes. This is the case if it's connecting
|
|
through windows hotspot, for instance. If so, give the mac address of the device. This
|
|
allows windows to look for the device's IP using "arp -a" and finding the matching
|
|
mac address. I haven't tested this on Linux or macOS.
|
|
|
|
[FPS]
|
|
|
|
FPS indicates the desired refresh rate, or frames-per-second, of the audio
|
|
visualization. The actual refresh rate may be lower if the computer cannot keep
|
|
up with desired FPS value.
|
|
|
|
Higher framerates improve "responsiveness" and reduce the latency of the
|
|
visualization but are more computationally expensive.
|
|
|
|
Low framerates are less computationally expensive, but the visualization may
|
|
appear "sluggish" or out of sync with the audio being played if it is too low.
|
|
|
|
The FPS should not exceed the maximum refresh rate of the LED strip, which
|
|
depends on how long the LED strip is.
|
|
|
|
[N_FFT_BINS]
|
|
|
|
Fast Fourier transforms are used to transform time-domain audio data to the
|
|
frequency domain. The frequencies present in the audio signal are assigned
|
|
to their respective frequency bins. This value indicates the number of
|
|
frequency bins to use.
|
|
|
|
A small number of bins reduces the frequency resolution of the visualization
|
|
but improves amplitude resolution. The opposite is true when using a large
|
|
number of bins. More bins is not always better!
|
|
|
|
There is no point using more bins than there are pixels on the LED strip.
