ADC Prescaler Notes:
|
||||||
|
--------------------
|
||||||
|
|
||||||
|
ADC Prescaler needs to be set so that the ADC input frequency is between 50 - 200kHz.
|
||||||
|
|
||||||
|
For more information, see table 17.5 "ADC Prescaler Selections" in
|
||||||
|
chapter 17.13.2 "ADCSRA – ADC Control and Status Register A"
|
||||||
|
(pages 140 and 141 on the complete ATtiny25/45/85 datasheet, Rev. 2586M–AVR–07/10)

/* fix_fft.c - Fixed-point in-place Fast Fourier Transform */
|
||||||
|
/*
|
||||||
|
All data are fixed-point short integers, in which -32768
|
||||||
|
to +32768 represent -1.0 to +1.0 respectively. Integer
|
||||||
|
arithmetic is used for speed, instead of the more natural
|
||||||
|
floating-point.
|
||||||
|
|
||||||
|
For the forward FFT (time -> freq), fixed scaling is
|
||||||
|
performed to prevent arithmetic overflow, and to map a 0dB
|
||||||
|
sine/cosine wave (i.e. amplitude = 32767) to two -6dB freq
|
||||||
|
coefficients. The return value is always 0.
|
||||||
|
|
||||||
|
For the inverse FFT (freq -> time), fixed scaling cannot be
|
||||||
|
done, as two 0dB coefficients would sum to a peak amplitude
|
||||||
|
of 64K, overflowing the 32k range of the fixed-point integers.
|
||||||
|
Thus, the fix_fft() routine performs variable scaling, and
|
||||||
|
returns a value which is the number of bits LEFT by which
|
||||||
|
the output must be shifted to get the actual amplitude
|
||||||
|
(i.e. if fix_fft() returns 3, each value of fr[] and fi[]
|
||||||
|
must be multiplied by 8 (2**3) for proper scaling.
|
||||||
|
Clearly, this cannot be done within fixed-point short
|
||||||
|
integers. In practice, if the result is to be used as a
|
||||||
|
filter, the scale_shift can usually be ignored, as the
|
||||||
|
result will be approximately correctly normalized as is.

* Light_WS2812 library example - Chained Writes
|
||||||
|
*
|
||||||
|
* This example shows how to use multiple calls without issuing a reset
|
||||||
|
* in between, allowing to send the same buffer to the string
|
||||||
|
* multiple times. This technique can be useful to conserve memory
|
||||||
|
* or to calculate LED colors on-the-fly.
|
||||||
|
*
|
||||||
|
* Please make sure to set your configuration in "WS2812_config.h" first
