If all the palette +// entries are changed at once, it can give a muddled appearance. +// However, if only a few palette entries are changed at once, +// you get a visually smoother transition: in the middle of the +// cross-fade your current palette will actually contain some +// colors from the old palette, a few blended colors, and some +// colors from the new palette. +// The maximum number of possible palette changes per call +// is 48 (sixteen color entries time three channels each). +// The default 'maximim number of changes' here is 12, meaning +// that only approximately a quarter of the palette entries +// will be changed per call. +void nblendPaletteTowardPalette( CRGBPalette16& currentPalette, + CRGBPalette16& targetPalette, + uint8_t maxChanges=24); + + + + +// You can also define a static RGB palette very compactly in terms of a series +// of connected color gradients. +// For example, if you want the first 3/4ths of the palette to be a slow +// gradient ramping from black to red, and then the remaining 1/4 of the +// palette to be a quicker ramp to white, you specify just three points: the +// starting black point (at index 0), the red midpoint (at index 192), +// and the final white point (at index 255).

In this particular case, +// I chose a sawtooth triangle wave (triwave8) rather than a sine wave, +// but the idea is the same: brightness = triwave8( time ). +// +// Of course, if all the pixels used the exact same wave form, and +// if they all used the exact same 'clock' for their 'time base', all +// the pixels would brighten and dim at once -- which does not look +// like twinkling at all. +// +// So to achieve random-looking twinkling, each pixel is given a +// slightly different 'clock' signal. Some of the clocks run faster, +// some run slower, and each 'clock' also has a random offset from zero. +// The net result is that the 'clocks' for all the pixels are always out +// of sync from each other, producing a nice random distribution +// of twinkles. +// +// The 'clock speed adjustment' and 'time offset' for each pixel +// are generated randomly. One (normal) approach to implementing that +// would be to randomly generate the clock parameters for each pixel +// at startup, and store them in some arrays. However, that consumes +// a great deal of precious RAM, and it turns out to be totally +// unnessary! If the random number generate is 'seeded' with the +// same starting value every time, it will generate the same sequence +// of values every time. So the clock adjustment parameters for each +// pixel are 'stored' in a pseudo-random number generator! The PRNG +// is reset, and then the first numbers out of it are the clock +// adjustment parameters for the first pixel, the second numbers out +// of it are the parameters for the second pixel, and so on. +// In this way, we can 'store' a stable sequence of thousands of +// random clock adjustment parameters in literally two bytes of RAM. +// +// There's a little bit of fixed-point math involved in applying the +// clock speed adjustments, which are expressed in eighths.

Falatic + * + * Modifications Copyright (c) 2018 Samuel Z. Guyer + * + * ESP32 support is provided using the RMT peripheral device -- a unit + * on the chip designed specifically for generating (and receiving) + * precisely-timed digital signals. Nominally for use in infrared + * remote controls, we use it to generate the signals for clockless + * LED strips. The main advantage of using the RMT device is that, + * once programmed, it generates the signal asynchronously, allowing + * the CPU to continue executing other code. It is also not vulnerable + * to interrupts or other timing problems that could disrupt the signal. + * + * The implementation strategy is borrowed from previous work and from + * the RMT support built into the ESP32 IDF. The RMT device has 8 + * channels, which can be programmed independently to send sequences + * of high/low bits. Memory for each channel is limited, however, so + * in order to send a long sequence of bits, we need to continuously + * refill the buffer until all the data is sent. To do this, we fill + * half the buffer and then set an interrupt to go off when that half + * is sent. Then we refill that half while the second half is being + * sent. This strategy effectively overlaps computation (by the CPU) + * and communication (by the RMT). + * + * Since the RMT device only has 8 channels, we need a strategy to + * allow more than 8 LED controllers. Our driver assigns controllers + * to channels on the fly, queuing up controllers as necessary until a + * channel is free. The main showPixels routine just fires off the + * first 8 controllers; the interrupt handler starts new controllers + * asynchronously as previous ones finish. So, for example, it can + * send the data for 8 controllers simultaneously, but 16 controllers + * would take approximately twice as much time. + * + * There is a #define that allows a program to control the total + * number of channels that the driver is allowed to use. It defaults + * to 8 -- use all the channels. Setting it to 1, for example, results + * in fully serial output: + * + * #define FASTLED_RMT_MAX_CHANNELS 1 + * + * OTHER RMT APPLICATIONS + * + * The default FastLED driver takes over control of the RMT interrupt + * handler, making it hard to use the RMT device for other + * (non-FastLED) purposes. You can change it's behavior to use the ESP + * core driver instead, allowing other RMT applications to + * co-exist. To switch to this mode, add the following directive + * before you include FastLED.h: + * + * #define FASTLED_RMT_BUILTIN_DRIVER + * + * There may be a performance penalty for using this mode. We need to + * compute the RMT signal for the entire LED strip ahead of time, + * rather than overlapping it with communication. We also need a large + * buffer to hold the signal specification. Each bit of pixel data is + * represented by a 32-bit pulse specification, so it is a 32X blow-up + * in memory use. + * + * + * Based on public domain code created 19 Nov 2016 by Chris Osborn + * http://insentricity.com * + * + */ +/* + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Guyer + * Derived from lots of code examples from other people. + * + * The I2S implementation can drive up to 24 strips in parallel, but + * with the following limitation: all the strips must have the same + * timing (i.e., they must all use the same chip). + * + * To enable the I2S driver, add the following line *before* including + * FastLED.h (no other changes are necessary): + * + * #define FASTLED_ESP32_I2S true + * + * The overall strategy is to use the parallel mode of the I2S "audio" + * peripheral to send up to 24 bits in parallel to 24 different pins. + * Unlike the RMT peripheral the I2S system cannot send bits of + * different lengths. Instead, we set the I2S data clock fairly high + * and then encode a signal as a series of bits. + * + * For example, with a clock divider of 10 the data clock will be + * 8MHz, so each bit is 125ns. The WS2812 expects a "1" bit to be + * encoded as a HIGH signal for around 875ns, followed by LOW for + * 375ns. Sending the following pattern results in the right shape + * signal: + * + * 1111111000 WS2812 "1" bit encoded as 10 125ns pulses + * + * The I2S peripheral expects the bits for all 24 outputs to be packed + * into a single 32-bit word. The complete signal is a series of these + * 32-bit values -- one for each bit for each strip. The pixel data, + * however, is stored "serially" as a series of RGB values separately + * for each strip. To prepare the data we need to do three things: (1) + * take 1 pixel from each strip, and (2) tranpose the bits so that + * they are in the parallel form, (3) translate each data bit into the + * bit pattern that encodes the signal for that bit. This code is in + * the fillBuffer() method: + * + * 1. Read 1 pixel from each strip into an array; store this data by + * color channel (e.g., all the red bytes, then all the green + * bytes, then all the blue bytes). For three color channels, the + * array is 3 X 24 X 8 bits. + * + * 2. Tranpose the array so that it is 3 X 8 X 24 bits. The hardware + * wants the data in 32-bit chunks, so the actual form is 3 X 8 X + * 32, with the low 8 bits unused. + * + * 3. Take each group of 24 parallel bits and "expand" them into a + * pattern according to the encoding. For example, with a 8MHz + * data clock, each data bit turns into 10 I2s pulses, so 24 + * parallel data bits turn into 10 X 24 pulses. + * + * We send data to the I2S peripheral using the DMA interface. We use + * two DMA buffers, so that we can fill one buffer while the other + * buffer is being sent. Each DMA buffer holds the fully-expanded + * pulse pattern for one pixel on up to 24 strips. The exact amount of + * memory required depends on the number of color channels and the + * number of pulses used to encode each bit. + * + * We get an interrupt each time a buffer is sent; we then fill that + * buffer while the next one is being sent. The DMA interface allows + * us to configure the buffers as a circularly linked list, so that it + * can automatically start on the next buffer. + */ +/* + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Guyer + * Copyright (c) 2017 Thomas Basler + * Copyright (c) 2017 Martin F. Falatic + * + * ESP32 support is provided using the RMT peripheral device -- a unit + * on the chip designed specifically for generating (and receiving) + * precisely-timed digital signals. Nominally for use in infrared + * remote controls, we use it to generate the signals for clockless + * LED strips. The main advantage of using the RMT device is that, + * once programmed, it generates the signal asynchronously, allowing + * the CPU to continue executing other code. It is also not vulnerable + * to interrupts or other timing problems that could disrupt the signal. + * + * The implementation strategy is borrowed from previous work and from + * the RMT support built into the ESP32 IDF. The RMT device has 8 + * channels, which can be programmed independently to send sequences + * of high/low bits. Memory for each channel is limited, however, so + * in order to send a long sequence of bits, we need to continuously + * refill the buffer until all the data is sent. To do this, we fill + * half the buffer and then set an interrupt to go off when that half + * is sent. Then we refill that half while the second half is being + * sent. This strategy effectively overlaps computation (by the CPU) + * and communication (by the RMT). + * + * Since the RMT device only has 8 channels, we need a strategy to + * allow more than 8 LED controllers. Our driver assigns controllers + * to channels on the fly, queuing up controllers as necessary until a + * channel is free. The main showPixels routine just fires off the + * first 8 controllers; the interrupt handler starts new controllers + * asynchronously as previous ones finish. So, for example, it can + * send the data for 8 controllers simultaneously, but 16 controllers + * would take approximately twice as much time. + * + * There is a #define that allows a program to control the total + * number of channels that the driver is allowed to use. It defaults + * to 8 -- use all the channels. Setting it to 1, for example, results + * in fully serial output: + * + * #define FASTLED_RMT_MAX_CHANNELS 1 + * + * OTHER RMT APPLICATIONS + * + * The default FastLED driver takes over control of the RMT interrupt + * handler, making it hard to use the RMT device for other + * (non-FastLED) purposes. You can change it's behavior to use the ESP + * core driver instead, allowing other RMT applications to + * co-exist. To switch to this mode, add the following directive + * before you include FastLED.h: + * + * #define FASTLED_RMT_BUILTIN_DRIVER + * + * There may be a performance penalty for using this mode. We need to + * compute the RMT signal for the entire LED strip ahead of time, + * rather than overlapping it with communication. We also need a large + * buffer to hold the signal specification. Each bit of pixel data is + * represented by a 32-bit pulse specification, so it is a 32X blow-up + * in memory use. + * + * + * Based on public domain code created 19 Nov 2016 by Chris Osborn + * http://insentricity.com * + * + */ +/* + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
