=New platform porting guide=
|
||||
|
||||
== Setting up the basic files/folders ==
|
||||
|
||||
* Create platform directory (e.g. platforms/arm/kl26)
|
||||
* Create configuration header led_sysdefs_arm_kl26.h:
|
||||
* Define platform flags (like FASTLED_ARM/FASTLED_TEENSY)
|
||||
* Define configuration parameters re: interrupts, or clock doubling
|
||||
* Include extar system header files if needed
|
||||
* Create main platform include, fastled_arm_kl26.h
|
||||
* Include the various other header files as needed
|
||||
* Modify led_sysdefs.h to conditionally include platform sysdefs header file
|
||||
* Modify platforms.h to conditionally include platform fastled header
|
||||
|
||||
== Porting fastpin.h ==
|
||||
|
||||
The heart of the FastLED library is the fast pin accesss. This is a templated class that provides 1-2 cycle pin access, bypassing digital write and other such things. As such, this will usually be the first bit of the library that you will want to port when moving to a new platform. Once you have FastPIN up and running then you can do some basic work like testing toggles or running bit-bang'd SPI output.
|
||||
|
||||
There's two low level FastPin classes. There's the base FastPIN template class, and then there is FastPinBB which is for bit-banded access on those MCUs that support bitbanding. Note that the bitband class is optional and primarily useful in the implementation of other functionality internal to the platform. This file is also where you would do the pin to port/bit mapping defines.
|
||||
|
||||
Explaining how the macros work and should be used is currently beyond the scope of this document.
|
||||
|
||||
== Porting fastspi.h ==
|
||||
|
||||
This is where you define the low level interface to the hardware SPI system (including a writePixels method that does a bunch of housekeeping for writing led data). Use the fastspi_nop.h file as a reference for the methods that need to be implemented. There are ofteh other useful methods that can help with the internals of the SPI code, I recommend taking a look at how the various platforms implement their SPI classes.
|
||||
|
||||
== Porting clockless.h ==
|
||||
|
||||
This is where you define the code for the clockless controllers. Across ARM platforms this will usually be fairly similar - though different arm platforms will have different clock sources that you can/should use.

IMPORTANT NOTE: For AVR based systems, avr-gcc 4.8.x is supported and tested. This means Arduino 1.6.5 and later.
|
||||
|
||||
|
||||
FastLED 3.2
|
||||
===========
|
||||
|
||||
This is a library for easily & efficiently controlling a wide variety of LED chipsets, like the ones
|
||||
sold by adafruit (Neopixel, DotStar, LPD8806), Sparkfun (WS2801), and aliexpress. In addition to writing to the
|
||||
leds, this library also includes a number of functions for high-performing 8bit math for manipulating
|
||||
your RGB values, as well as low level classes for abstracting out access to pins and SPI hardware, while
|
||||
still keeping things as fast as possible. Tested with Arduino up to 1.6.5 from arduino.cc.
|
||||
|
||||
Quick note for people installing from GitHub repo zips, rename the folder FastLED before copying it to your Arduino/libraries folder. Github likes putting -branchname into the name of the folder, which unfortunately, makes Arduino cranky!
|
||||
|
||||
We have multiple goals with this library:
|
||||
|
||||
* Quick start for new developers - hook up your leds and go, no need to think about specifics of the led chipsets being used
|
||||
* Zero pain switching LED chipsets - you get some new leds that the library supports, just change the definition of LEDs you're using, et. voila! Your code is running with the new leds.
|
||||
* High performance - with features like zero cost global brightness scaling, high performance 8-bit math for RGB manipulation, and some of the fastest bit-bang'd SPI support around, FastLED wants to keep as many CPU cycles available for your led patterns as possible
|
||||
|
||||
## Getting help
|
||||
|
||||
If you need help with using the library, please consider going to the google+ community first, which is at http://fastled.io/+ - there are hundreds of people in that group and many times you will get a quicker answer to your question there, as you will be likely to run into other people who have had the same issue. If you run into bugs with the library (compilation failures, the library doing the wrong thing), or if you'd like to request that we support a particular platform or LED chipset, then please open an issue at http://fastled.io/issues and we will try to figure out what is going wrong.
|
||||
|
||||
## Simple example
|
||||
|
||||
How quickly can you get up and running with the library? Here's a simple blink program:
|
||||
|
||||
#include "FastLED.h"
|
||||
#define NUM_LEDS 60
|
||||
CRGB leds[NUM_LEDS];
|
||||
void setup() { FastLED.addLeds<NEOPIXEL, 6>(leds, NUM_LEDS); }
|
||||
void loop() {
|
||||
leds[0] = CRGB::White; FastLED.show(); delay(30);

## Supported LED chipsets
|
||||
|
||||
Here's a list of all the LED chipsets are supported. More details on the led chipsets are included *TODO: Link to wiki page*
|
||||
|
||||
* Adafruit's DotStars - AKA the APA102
|
||||
* Adafruit's Neopixel - aka the WS2812B (also WS2811/WS2812/WS2813, also supported in lo-speed mode) - a 3 wire addressable led chipset
|
||||
* TM1809/4 - 3 wire chipset, cheaply available on aliexpress.com
|
||||
* TM1803 - 3 wire chipset, sold by radio shack
|
||||
* UCS1903 - another 3 wire led chipset, cheap
|
||||
* GW6205 - another 3 wire led chipset
|
||||
* LPD8806 - SPI based chpiset, very high speed
|
||||
* WS2801 - SPI based chipset, cheap and widely available
|
||||
* SM16716 - SPI based chipset
|
||||
* APA102 - SPI based chipset
|
||||
* P9813 - aka Cool Neon's Total Control Lighting
|
||||
* DMX - send rgb data out over DMX using arduino DMX libraries
|
||||
* SmartMatrix panels - needs the SmartMatrix library - https://github.com/pixelmatix/SmartMatrix
|
||||
* LPD6803 - SPI based chpiset, chip CMODE pin must be set to 1 (inside oscillator mode)
|
||||
|
||||
|
||||
HL1606, and "595"-style shift registers are no longer supported by the library. The older Version 1 of the library ("FastSPI_LED") has support for these, but is missing many of the advanced features of current versions and is no longer being maintained.
|
||||
|
||||
|
||||
## Supported platforms
|
||||
|
||||
Right now the library is supported on a variety of arduino compatable platforms. If it's ARM or AVR and uses the arduino software (or a modified version of it to build) then it is likely supported. Note that we have a long list of upcoming platforms to support, so if you don't see what you're looking for here, ask, it may be on the roadmap (or may already be supported). N.B. at the moment we are only supporting the stock compilers that ship with the arduino software. Support for upgraded compilers, as well as using AVR studio and skipping the arduino entirely, should be coming in a near future release.
|
||||
|
||||
* Arduino & compatibles - straight up arduino devices, uno, duo, leonardo, mega, nano, etc...
|
||||
* Arduino Yún
|
||||
* Adafruit Trinket & Gemma - Trinket Pro may be supported, but haven't tested to confirm yet
|
||||
* Teensy 2, Teensy++ 2, Teensy 3.0, Teensy 3.1/3.2, Teensy LC - arduino compataible from pjrc.com with some extra goodies (note the teensy 3, 3.1, and LC are ARM, not AVR!)
|
||||
* Arduino Due and the digistump DigiX
|
||||
* RFDuino
|
||||
* SparkCore
|
||||
* Arduino Zero
|
||||
* ESP8266 using the arduino board definitions from http://arduino.esp8266.com/stable/package_esp8266com_index.json - please be sure to also read https://github.com/FastLED/FastLED/wiki/ESP8266-notes for information specific to the 8266.
|
||||
* The wino board - http://wino-board.com
|
||||
|
||||
What types of platforms are we thinking about supporting in the future? Here's a short list: ChipKit32, Maple, Beagleboard
|
||||
|
||||
## What about that name?
|
||||
|
||||
Wait, what happend to FastSPI_LED and FastSPI_LED2? The library was initially named FastSPI_LED because it was focused on very fast and efficient SPI access. However, since then, the library has expanded to support a number of LED chipsets that don't use SPI, as well as a number of math and utility functions for LED processing across the board. We decided that the name FastLED more accurately represents the totality of what the library provides, everything fast, for LEDs.

// has 256 entries, each containing a specific 24-bit RGB color. You can then
|
||||
// index into the color palette using a simple 8-bit (one byte) value.
|
||||
// A 256-entry color palette takes up 768 bytes of RAM, which on Arduino
|
||||
// is quite possibly "too many" bytes.
|
||||
//
|
||||
// FastLED does offer traditional 256-element palettes, for setups that
|
||||
// can afford the 768-byte cost in RAM.
|
||||
//
|
||||
// However, FastLED also offers a compact alternative. FastLED offers
|
||||
// palettes that store 16 distinct entries, but can be accessed AS IF
|
||||
// they actually have 256 entries; this is accomplished by interpolating
|
||||
// between the 16 explicit entries to create fifteen intermediate palette
|
||||
// entries between each pair.
|
||||
//
|
||||
// So for example, if you set the first two explicit entries of a compact
|
||||
// palette to Green (0,255,0) and Blue (0,0,255), and then retrieved
|
||||
// the first sixteen entries from the virtual palette (of 256), you'd get
|
||||
// Green, followed by a smooth gradient from green-to-blue, and then Blue.

// programmable color palette, instead of through the "HeatColor(...)" function.
|

//
|

// Four different static color palettes are provided here, plus one dynamic one.
|

//
|

// The three static ones are:

// 1. the FastLED built-in HeatColors_p -- this is the default, and it looks
|

// pretty much exactly like the original Fire2012.
|
||||
//
|
||||
// To use any of the other palettes below, just "uncomment" the corresponding code.
|
||||
//
|
||||
// 2. a gradient from black to red to yellow to white, which is
|
||||
// visually similar to the HeatColors_p, and helps to illustrate
|
||||
// what the 'heat colors' palette is actually doing,
|
||||
// 3. a similar gradient, but in blue colors rather than red ones,
|
||||
// i.e. from black to blue to aqua to white, which results in
|
||||
// an "icy blue" fire effect,
|
||||
// 4. a simplified three-step gradient, from black to red to white, just to show
|
||||
// that these gradients need not have four components; two or
|
||||
// three are possible, too, even if they don't look quite as nice for fire.
|
||||
//
|
||||
// The dynamic palette shows how you can change the basic 'hue' of the
|

// color palette every time through the loop, producing "rainbow fire".

// This basic one-dimensional 'fire' simulation works roughly as follows:
|
||||
// There's a underlying array of 'heat' cells, that model the temperature
|
||||
// at each point along the line. Every cycle through the simulation,
|
||||
// four steps are performed:
|
||||
// 1) All cells cool down a little bit, losing heat to the air
|
||||
// 2) The heat from each cell drifts 'up' and diffuses a little
|
||||
// 3) Sometimes randomly new 'sparks' of heat are added at the bottom
|
||||
// 4) The heat from each cell is rendered as a color into the leds array
|
||||
// The heat-to-color mapping uses a black-body radiation approximation.
|
||||
//
|
||||
// Temperature is in arbitrary units from 0 (cold black) to 255 (white hot).
|
||||
//
|
||||
// This simulation scales it self a bit depending on NUM_LEDS; it should look
|
||||
// "OK" on anywhere from 20 to 100 LEDs without too much tweaking.
|
||||
//
|
||||
// I recommend running this simulation at anywhere from 30-100 frames per second,
|
||||
// meaning an interframe delay of about 10-35 milliseconds.
|
||||
//
|
||||
// Looks best on a high-density LED setup (60+ pixels/meter).
|
||||
//
|
||||
//
|
||||
// There are two main parameters you can play with to control the look and
|
||||
// feel of your fire: COOLING (used in step 1 above), and SPARKING (used
|
||||
// in step 3 above).
|
||||
//
|
||||

|
||||
// Default 55, suggested range 20-100
|
||||
#define COOLING 55
|

|
||||
// SPARKING: What chance (out of 255) is there that a new spark will be lit?

// throughout your code.
|
||||
//
|
||||
// It requires a careful attention to get it set up correctly, but
|
||||
// can potentially make your code smaller and faster.
|
||||
//
|
||||
// Suppose you have an 8 x 5 matrix of 40 LEDs. Normally, you'd
|
||||
// delcare your leds array like this:
|
||||
// CRGB leds[40];
|
||||
// But instead of that, declare an LED buffer with one extra pixel in
|
||||
// it, "leds_plus_safety_pixel". Then declare "leds" as a pointer to
|
||||
// that array, but starting with the 2nd element (id=1) of that array:
|
||||
// CRGB leds_with_safety_pixel[41];
|
||||
// CRGB* const leds( leds_plus_safety_pixel + 1);
|
||||
// Then you use the "leds" array as you normally would.
|
||||
// Now "leds[0..N]" are aliases for "leds_plus_safety_pixel[1..(N+1)]",
|
||||
// AND leds[-1] is now a legitimate and safe alias for leds_plus_safety_pixel[0].
|
||||
// leds_plus_safety_pixel[0] aka leds[-1] is now your "safety pixel".
|
||||
//
|
||||
// Now instead of using the XY function above, use the one below, "XYsafe".
|
||||
//
|
||||
// If the X and Y values are 'in bounds', this function will return an index
|
||||
// into the visible led array, same as "XY" does.
|
||||
// HOWEVER -- and this is the trick -- if the X or Y values
|
||||
// are out of bounds, this function will return an index of -1.
|
||||
// And since leds[-1] is actually just an alias for leds_plus_safety_pixel[0],
|
||||
// it's a totally safe and legal place to access. And since the 'safety pixel'
|
||||
// falls 'outside' the visible part of the LED array, anything you write
|
||||
// there is hidden from view automatically.
|
||||
// Thus, this line of code is totally safe, regardless of the actual size of
|
||||
// your matrix:
|
||||
// leds[ XYsafe( random8(), random8() ) ] = CHSV( random8(), 255, 255);
|
||||
//
|
||||
// The only catch here is that while this makes it safe to read from and
|
||||
// write to 'any pixel', there's really only ONE 'safety pixel'. No matter
|
||||
// what out-of-bounds coordinates you write to, you'll really be writing to
|
||||
// that one safety pixel. And if you try to READ from the safety pixel,

// were supplied.

// FastLED_FillSolid_Hue_X:
|
||||
// fill led array with solid HSV Hue
|
||||
// FastLED_Random8:
|
||||
// return a pseudorandom number in A
|
||||
// FastLED_FillRainbow_XY:
|
||||
// fill led array with HSV rainbow
|
||||
// starting at hue X, incrementing by
|
||||
// huedelta Y each pixel.
|
||||
// FastLED_SetHue_XY:
|

// set pixel Y to HSV hue X
|

// FastLED_Beat8:
|

// takes a speed increment in A, and
|

// returns a triangle wave in A.
|

//
|
||||
//
|
||||
// NOTES:
|
||||
// For speed and size, there IS some
|
||||
// self-modifying code in this
|
||||
// library, so it cannot be burned
|
||||
// into ROM without modification.
|
||||
// Brightness control only works on
|
||||
// APA102 at this point.
|
||||
// Pin 15 is currently used as a
|
||||
// 'frame start' signal for protocol
|
||||
// diagnostics - makes frames more
|
||||
// visible with an oscilloscope.
|
||||
// If Pin 5 is specified for the CLOCK
|
||||
// output pin, FastLED6502 will
|
||||
// automatically use the high speed
|
||||
// C040STROBE signal for clock. Note
|
||||
// that the Apple //gs lacks this
|
||||
// signal, even on the motherboard
|
||||
// game port.
|
||||
// The Apple joystick/mouse port on the
|
||||
// rear of the //c, //c+, and //gs
|
||||
// can NOT be used for LED connections
|
||||
// because it lacks the necessary
|
||||
// digital output pins.
|
||||
// This library can drive 100 LED pixels
|
||||
// at more than 30 frames per second.

|

// NOTE 1: This function is a long-term work in process; expect
|
||||
// results to change slightly over time as this function is
|
||||
// refined and improved.
|
||||
//
|
||||
// NOTE 2: This function is most accurate when the input is an
|
||||
// RGB color that came from a fully-saturated HSV color to start
|
||||
// with. E.g. CHSV( hue, 255, 255) -> CRGB -> CHSV will give
|
||||
// best results.
|
||||
//
|
||||
// NOTE 3: This function is not nearly as fast as HSV-to-RGB.
|
||||
// It is provided for those situations when the need for this
|
||||
// function cannot be avoided, or when extremely high performance
|
||||
// is not needed.
|
||||
//
|
||||
// NOTE 4: Why is this 'only' an "approximation"?
|
||||
// Not all RGB colors have HSV equivalents! For example, there
|
||||
// is no HSV value that will ever convert to RGB(255,255,0) using
|
||||
// the code provided in this library. So if you try to
|
||||
// convert RGB(255,255,0) 'back' to HSV, you'll necessarily get
|
||||
// only an approximation. Emphasis has been placed on getting
|
||||
// the 'hue' as close as usefully possible, but even that's a bit
|
||||
// of a challenge. The 8-bit HSV and 8-bit RGB color spaces
|
||||
// are not a "bijection".
|
||||
//
|
||||
// Nevertheless, this function does a pretty good job, particularly
|
||||
// at recovering the 'hue' from fully saturated RGB colors that
|
||||
// originally came from HSV rainbow colors. So if you start
|
||||
// with CHSV(hue_in,255,255), and convert that to RGB, and then
|
||||
// convert it back to HSV using this function, the resulting output
|
||||
// hue will either exactly the same, or very close (+/-1).
|
||||
// The more desaturated the original RGB color is, the rougher the
|
||||
// approximation, and the less accurate the results.
|
||||
//
