Set the maximum power to be used, given in volts and milliamps. @param volts - how many volts the leds are being driven at (usually 5) @param milliamp

square root for 16-bit integers About three times faster and five times smaller than Arduino's general sqrt on AVR.

A raw set of writing byte values, assumes setup/init/waiting done elsewhere (static for use by adjustment classes)

This function sets up a palette of purple and green stripes.

This function fills the palette with totally random colors.

take abs() of a signed 8-bit uint8_t

blurColumns: perform a blur1d on each column of a rectangular matrix

blurRows: perform a blur1d on every row of a rectangular matrix

zero out the led data managed by this controller

Helper routine to divide a 32-bit value by 1024, returning only the low 16 bits. You'd think this would be just result = (in32 >> 10) & 0xFFFF; and on

ease8InOutCubic: 8-bit cubic ease-in / ease-out function Takes around 18 cycles on AVR

-- Fill RMT buffer Puts 32 bits of pixel data into the next 32 slots in the RMT memory Each data bit is represented by a 32-bit RMT item that specifie

-- Get or create the buffer for the pixel data We can't allocate it ahead of time because we don't have the PixelController object until show is calle

-- Init pulse buffer Set up the buffer that will hold all of the pulse items for this controller. This function is only used when the built-in RMT dri

__attribute__ ((noinline))

this will always be the most efficient if you ask for a buffer that's as large as the capture buffer

__attribute__ ((noinline))

8x8 bit multiplication, with 8 bit result

Some chipsets pre-cycle the first byte, which means we want to cycle byte 0's dithering separately

Set the 16-bit seed used for the random number generator

selectBasedOnHashBit performs this: result = (hash & (1<<bitnumber)) ? a : b but with an AVR asm version that's smaller and quicker than C (and probab

Set the maximum power to be used, given in milliwatts @param milliwatts - the max power draw desired, in milliwatts

show function using the "attached to this controller" led data

-- Start this controller on the given channel This function just initiates the RMT write; it does not wait for it to finish.

Simplified form of bits rotating function. Based on code found here - http://www.hackersdelight.org/hdcodetxt/transpose8.c.txt - rotating data into L
