Usually one's sketch is implicitly using this time to generate a new frame of animation.but if it finishes very quickly, this function could be used to see if there's some idle time available for some low-priority concurrent task. NeoPixels require a short quiet time (about 300 microseconds) after the last bit is received before the data 'latches' and new data can start being received. More.Ĭheck whether a call to show() will start sending data immediately or will 'block' for a required interval. Otherwise, the old data will remain in RAM and is not reordered to the new format, so it's advisable to follow up with clear(). If format changes from one of the RGB variants to an RGBW variant (or RGBW to RGB), the old data will be deallocated and new data is cleared. More.Ĭhange the pixel format of a previously-declared Adafruit_NeoPixel strip object. Pin number and pixel format are unchanged. Old data is deallocated and new data is cleared. More.įill the whole NeoPixel strip with 0 / black / off.Ĭhange the length of a previously-declared Adafruit_NeoPixel strip object. The next call to show() will refresh the LEDs at this level. Does not immediately affect what's currently displayed on the LEDs. More.įill (uint32_t c=0, uint16_t first=0, uint16_t count=0)įill all or part of the NeoPixel strip with a color. Set a pixel's color using a 32-bit 'packed' RGB or RGBW value. Set a pixel's color using separate red, green, blue and white components (for RGBW NeoPixels only). SetPixelColor (uint16_t n, uint8_t r, uint8_t g, uint8_t b, uint8_t w) If using RGBW pixels, white will be set to 0. Set a pixel's color using separate red, green and blue components. SetPixelColor (uint16_t n, uint8_t r, uint8_t g, uint8_t b) Previous pin, if any, is set to INPUT and the new pin is set to OUTPUT. Set/change the NeoPixel output pin number. More.ĭeallocate Adafruit_NeoPixel object, set data pin back to INPUT. "Empty" NeoPixel constructor when length, pin and/or pixel type are not known at compile-time, and must be initialized later with updateType(), updateLength() and setPin(). NeoPixel constructor when length, pin and pixel type are known at compile-time. Class that stores state and functions for interacting with Adafruit NeoPixels and compatible devices.Īdafruit_NeoPixel (uint16_t n, int16_t pin=6, neoPixelType type= NEO_GRB+ NEO_KHZ800)
