Contains definitions that can be used to configure FastLED at compile time.

#include "FastLED.h"Go to the source code of this file.
Macros | |
| #define | FASTLED_SCALE8_FIXED 1 |
| Use this to toggle whether or not to use the "fixed" FastLED scale8(). | |
| #define | FASTLED_BLEND_FIXED 1 |
| Use this to toggle whether to use "fixed" FastLED pixel blending, including ColorFromPalette. | |
| #define | FASTLED_NOISE_FIXED 1 |
| Use this to toggle whether to use "fixed" FastLED 8-bit and 16-bit noise functions. | |
| #define | FASTLED_FORCE_SOFTWARE_PINS |
| Use this option only for debugging pin access and forcing software pin access. | |
| #define | FASTLED_FORCE_SOFTWARE_SPI |
| Use this option only for debugging bitbang'd SPI access or to work around bugs in hardware SPI access. | |
| #define | FASTLED_ALLOW_INTERRUPTS |
| Use this to force FastLED to allow interrupts in the clockless chipsets (or to force it to disallow), overriding the default on platforms that support this. | |
| #define | FASTLED_NOISE_ALLOW_AVERAGE_TO_OVERFLOW 0 |
| Use this to allow some integer overflows/underflows in the inoise() functions. | |
| #define | FASTLED_INTERRUPT_RETRY_COUNT 2 |
| Use this to determine how many times FastLED will attempt to re-transmit a frame if interrupted for too long by interrupts. | |
| #define | FASTLED_USE_GLOBAL_BRIGHTNESS 0 |
| Use this toggle to enable global brightness in contollers that support is (e.g. | |
| #define FASTLED_ALLOW_INTERRUPTS |
Use this to force FastLED to allow interrupts in the clockless chipsets (or to force it to disallow), overriding the default on platforms that support this.
Set the value to 1 to allow interrupts or 0 to disallow them.

| #define FASTLED_BLEND_FIXED 1 |
Use this to toggle whether to use "fixed" FastLED pixel blending, including ColorFromPalette.
The prior pixel blend functions had integer-rounding math errors that led to small errors being inadvertently added to the low bits of blended colors, including colors retrieved from color palettes using LINEAR_BLEND. This is now fixed, and the fix is enabled by default. However, if for some reason you wish to run with the old blending, including the integer rounding and color errors, you can disable the bugfix here.

| #define FASTLED_FORCE_SOFTWARE_PINS |
Use this option only for debugging pin access and forcing software pin access.
Forces use of digitalWrite() methods for pin access vs. direct hardware port access.
Definition at line 84 of file fastled_config.h.
| #define FASTLED_FORCE_SOFTWARE_SPI |
Use this option only for debugging bitbang'd SPI access or to work around bugs in hardware SPI access.
Forces use of bit-banged SPI, even on pins that have hardware SPI available.

| #define FASTLED_INTERRUPT_RETRY_COUNT 2 |
Use this to determine how many times FastLED will attempt to re-transmit a frame if interrupted for too long by interrupts.
Definition at line 88 of file fastled_config.h.
| #define FASTLED_NOISE_ALLOW_AVERAGE_TO_OVERFLOW 0 |
Use this to allow some integer overflows/underflows in the inoise() functions.
The original implementions allowed this, and had some discontinuties in the noise output. It's technically an implementation bug, and was fixed, but you may wish to preserve the old look and feel of the inoise() functions in your existing animations.
The default is 0: NO overflow, and 'continuous' noise output, aka the fixed way.
Definition at line 87 of file fastled_config.h.
| #define FASTLED_NOISE_FIXED 1 |
Use this to toggle whether to use "fixed" FastLED 8-bit and 16-bit noise functions.
The prior noise functions had some math errors that led to "discontinuities" in the output, which by definition should be smooth and continuous. The bug led to noise function output that had "edges" and glitches in it. This is now fixed, and the fix is enabled by default. However, if for some reason you wish to run with the old noise code, including the glitches, you can disable the bugfix here.
Definition at line 62 of file fastled_config.h.
| #define FASTLED_SCALE8_FIXED 1 |
Use this to toggle whether or not to use the "fixed" FastLED scale8().
The initial scale8() had a problem where scale8(255,255) would give you 254. This is now fixed, and that fix is enabled by default. However, if for some reason you have code that is not working right as a result of this (e.g. code that was expecting the old scale8() behavior) you can disable it here.

| #define FASTLED_USE_GLOBAL_BRIGHTNESS 0 |
Use this toggle to enable global brightness in contollers that support is (e.g.
ADA102 and SK9822). It changes how color scaling works and uses global brightness before scaling down color values. This enables much more accurate color control on low brightness settings.
