This PWM pin and the timer must not be used. OctoWS2811 uses internally uses a timer, and a PWM waveform at a pin on someīoards.
If a custom pin list is not specified, the same group of 8 pins Larger than 8 pins! In Arduino, open File > Examples > OctoWS2811 > Teensy4_PinListįor details. Teensy 4.0 and Teensy 4.1 can use any group of pins, even groups smaller or ** Default pins when custom pin list is not used * Pin 12 only used by VideoDisplay example May be used, with addressing described below. AC mains voltage should be wired properly according to electrical codes.Įight LED strips should be connected as shown. Large LED arrays consume considerable power. Aĭiffusing material in front the LEDs is usually a good idea. Teensy 4.x boards support use of any set of pins, not limited to only 8 fixed pins. OctoWS2811 requires the DMA (Direct Memory Access) engine which is available You MUST use a 74HCT245 or similar buffer chip to increase Teensy'sģ.3V signal to 5 volts for compatibility with these newer WS2812B LED strips.ĥV buffer hardware must be used for reliable signals to large LED projects. Update: Some of the latest WS2812B LED strips With a frame sync signal for precise refresh timing. Scaling to extremely large LED installations using multiple Teensy 3.x boards Minimal CPU impact and doubleīuffering allows complex animation. OctoWS2811 is a high performance WS2811 & WS2812 & WS2812B LED library, written by Paul Stoffregen,įeaturing simultaneous update to 8 LED strips using efficient Reliable communication from Teensy 3.2 to large LED projects.
