2021-11-17Add pin support for new ESP32 variantsJason Tranchida
* Add support for C3, S3, and H2 * Update pin definition mechanism to be to support multiple variants * Fix S2 mapping that were excluding base ESP32 pin masking

2021-08-27Refactor blend8() to apply the same optimisations on all platforms (in BLEND_C).Ben Isaacs
As noted on https://github.com/FastLED/FastLED/pull/1288, many platforms can eliminate an entire multiplication this way.
2021-08-26Using an | instead of + is 4 instructions faster.Ben Isaacs
2021-08-26Improve the speed of blend8 on AVR by 20-30%Ben Isaacs
The SCALE8_FIXED version of blend8 uses the formula result = (A*(255-amountOfB) + A + B*amountOfB + B) >> 8 However, by rearranging this to result = (256*A + B - A*amountOfB + B*amountOfB) >> 8 We can save 4 or 5 cycles (depending on how the optimiser sets up a and b inputs for that extra cycle) This formula rearrangement may be advantageous for the C implementation too, but I haven't tried that.
2021-08-09Add fill_rainbow_endless util functionsDavid Madison
For filling a rainbow pattern that's continuous in hue between the end of the strip and the beginning. Useful for out-of-the-box rainbow animations on looped strips and LED rings.
2021-08-01Make the minimum wait optional by defining NO_MINIMUM_WAITBen Isaacs
You may want this if you are doing your own frame-rate accounting and don't want to waste cycles. You may also want this if you are intentionally calling show() multiple times for the same strip.
2021-08-01Fix sense of check - this warning is ONLY if you're trying to disable clock ↵Ben Isaacs
correction without also enabling interrupts
2021-08-01Fix the printout of warnings and make warning message clearer.Ben Isaacs
2021-08-01Change define NO_CORRECTION in clockless_trinket to NO_CLOCK_CORRECTION (#1263)Ben Isaacs
The more specific use is in clockless_trinket, so this is the one which has been renamed. It was only relevant if you also had FASTLED_ALLOW_INTERRUPTS defined. Existing code will still work exactly the same, but in cases where this define would have altered the code, a warning is now emitted as well.
2021-08-01Don't assume mAdvance is always 3.Ben Isaacs
2021-08-01Tweak Controller::showLeds() to infer reversal from negative strip lengthBen Isaacs
Example usage: ``` Show forward: FastLED[0].setLeds(&leds[0], STRIP_LENGTH); FastLED.show(); Show in reverse: FastLED[0].setLeds(&leds[STRIP_LENGTH-1], -STRIP_LENGTH); FastLED.show(); ```
2021-08-01Tweak clockless trinket to handle negative advanceBy values (that is, ↵Ben Isaacs
showing pixels in reverse).
2021-07-29Prevent FastLED from hanging on 0-length pixel arraysBen Isaacs
Without this patch, a 0 length pixel array is treated as if it's 65535 long. Whilst few people will encounter this bug in simple applications, it comes up frequently when manipulating ranges of pixels with multiple PixelControllers.
2021-07-29Remove clobbering of TCCR0A left over from ancient timesBen Isaacs
Daniel Garcia commented out all of the other code which goes with this block in b9b23091 (2015). Remove this last remnant.

Add scale8(uint8) -- which may cause a behavior change if a uint32_t was being passed in, but this is definitely a 'fix'.

2021-06-22Fix incorrectly calling perlin noise "Simplex Noise"Ayke van Laethem
Simplex noise is something different and is not implemented by the FastLED library (yet!). Therefore, don't confuse people by calling it Simplex Noise.

Some Modernization updates for #1208
2021-04-05matrix x,y indicies changed back to uint8_tMarc Miller
Matrix examples x,y indicies changed back to uint8_t but returned pixel number kept as uint16_t Added "Params for width and height" and "Param for different pixel layouts" comment lines to match other matrix examples. In NoisePlayground changed #define kMatrixWidth to const uint8_t kMatrixWidth to match format in other matrix examples.
2021-04-04Some Modernization updates for #1208Marc Miller
As suggested in #1208 this updates: LEDS.[function] to FastLED.[function] Switch from byte to uint8_t Use uint16_t for all LED index variables Remove messages about minimum version

not 255, e.g. in fill_rainbow, as used in DemoReel100.
2021-03-23Minor cleanup to HSV code. It had been compiling differently recently on AVR ↵Mark Kriegsman
Arduinos, leading (sometimes) to a visible red pixel in the middle of the yellow part of the rainbow, and possibly other color glitches. I believe this fixes #1188.
