#ifndef __INC_LIB8TION_H
#define __INC_LIB8TION_H
/*
Fast, efficient 8-bit math functions specifically
designed for high-performance LED programming.
Because of the AVR(Arduino) and ARM assembly language
implementations provided, using these functions often
results in smaller and faster code than the equivalent
program using plain "C" arithmetic and logic.
Included are:
- Saturating unsigned 8-bit add and subtract.
Instead of wrapping around if an overflow occurs,
these routines just 'clamp' the output at a maxumum
of 255, or a minimum of 0. Useful for adding pixel
values. E.g., qadd8( 200, 100) = 255.
qadd8( i, j) == MIN( (i + j), 0xFF )
qsub8( i, j) == MAX( (i - j), 0 )
- Saturating signed 8-bit ("7-bit") add.
qadd7( i, j) == MIN( (i + j), 0x7F)
- Scaling (down) of unsigned 8- and 16- bit values.
Scaledown value is specified in 1/256ths.
scale8( i, sc) == (i * sc) / 256
scale16by8( i, sc) == (i * sc) / 256
Example: scaling a 0-255 value down into a
range from 0-99:
downscaled = scale8( originalnumber, 100);
A special version of scale8 is provided for scaling
LED brightness values, to make sure that they don't
accidentally scale down to total black at low
dimming levels, since that would look wrong:
scale8_video( i, sc) = ((i * sc) / 256) +? 1
Example: reducing an LED brightness by a
dimming factor:
new_bright = scale8_video( orig_bright, dimming);
- Fast 8- and 16- bit unsigned random numbers.
Significantly faster than Arduino random(), but
also somewhat less random. You can add entropy.
random8() == random from 0..255
random8( n) == random from 0..(N-1)
random8( n, m) == random from N..(M-1)
random16() == random from 0..65535
random16( n) == random from 0..(N-1)
random16( n, m) == random from N..(M-1)
random16_set_seed( k) == seed = k
random16_add_entropy( k) == seed += k
- Absolute value of a signed 8-bit value.
abs8( i) == abs( i)
- 8-bit math operations which return 8-bit values.
These are provided mostly for completeness,
not particularly for performance.
mul8( i, j) == (i * j) & 0xFF
add8( i, j) == (i + j) & 0xFF
sub8( i, j) == (i - j) & 0xFF
- Fast 16-bit approximations of sin and cos.
Input angle is a uint16_t from 0-65535.
Output is a signed int16_t from -32767 to 32767.
sin16( x) == sin( (x/32768.0) * pi) * 32767
cos16( x) == cos( (x/32768.0) * pi) * 32767
Accurate to more than 99% in all cases.
- Fast 8-bit approximations of sin and cos.
Input angle is a uint8_t from 0-255.
Output is an UNsigned uint8_t from 0 to 255.
sin8( x) == (sin( (x/128.0) * pi) * 128) + 128
cos8( x) == (cos( (x/128.0) * pi) * 128) + 128
Accurate to within about 2%.
- Fast 8-bit "easing in/out" function.
ease8InOutCubic(x) == 3(x^i) - 2(x^3)
ease8InOutApprox(x) ==
faster, rougher, approximation of cubic easing
ease8InOutQuad(x) == quadratic (vs cubic) easing
- Cubic, Quadratic, and Triangle wave functions.
Input is a uint8_t representing phase withing the wave,
similar to how sin8 takes an angle 'theta'.
Output is a uint8_t representing the amplitude of
the wave at that point.
cubicwave8( x)
quadwave8( x)
triwave8( x)
- Square root for 16-bit integers. About three times
faster and five times smaller than Arduino's built-in
generic 32-bit sqrt routine.
sqrt16( uint16_t x ) == sqrt( x)
- Dimming and brightening functions for 8-bit
light values.
dim8_video( x) == scale8_video( x, x)
dim8_raw( x) == scale8( x, x)
dim8_lin( x) == (x<128) ? ((x+1)/2) : scale8(x,x)
brighten8_video( x) == 255 - dim8_video( 255 - x)
brighten8_raw( x) == 255 - dim8_raw( 255 - x)
brighten8_lin( x) == 255 - dim8_lin( 255 - x)
The dimming functions in particular are suitable
for making LED light output appear more 'linear'.
- Linear interpolation between two values, with the
fraction between them expressed as an 8- or 16-bit
fixed point fraction (fract8 or fract16).
lerp8by8( fromU8, toU8, fract8 )
lerp16by8( fromU16, toU16, fract8 )
lerp15by8( fromS16, toS16, fract8 )
== from + (( to - from ) * fract8) / 256)
lerp16by16( fromU16, toU16, fract16 )
== from + (( to - from ) * fract16) / 65536)
map8( in, rangeStart, rangeEnd)
== map( in, 0, 255, rangeStart, rangeEnd);
- Optimized memmove, memcpy, and memset, that are
faster than standard avr-libc 1.8.
memmove8( dest, src, bytecount)
memcpy8( dest, src, bytecount)
memset8( buf, value, bytecount)
- Beat generators which return sine or sawtooth
waves in a specified number of Beats Per Minute.
Sine wave beat generators can specify a low and
high range for the output. Sawtooth wave beat
generators always range 0-255 or 0-65535.
beatsin8( BPM, low8, high8)
= (sine(beatphase) * (high8-low8)) + low8
beatsin16( BPM, low16, high16)
= (sine(beatphase) * (high16-low16)) + low16
beatsin88( BPM88, low16, high16)
= (sine(beatphase) * (high16-low16)) + low16
beat8( BPM) = 8-bit repeating sawtooth wave
beat16( BPM) = 16-bit repeating sawtooth wave
beat88( BPM88) = 16-bit repeating sawtooth wave
BPM is beats per minute in either simple form
e.g. 120, or Q8.8 fixed-point form.
BPM88 is beats per minute in ONLY Q8.8 fixed-point
form.
Lib8tion is pronounced like 'libation': lie-BAY-shun
