Required Connections | |
-------------------- | |
pin 2: LED Strip #1 OctoWS2811 drives 8 LED Strips. | |
pin 14: LED strip #2 All 8 are the same length. | |
pin 7: LED strip #3 | |
pin 8: LED strip #4 A 100 ohm resistor should used | |
pin 6: LED strip #5 between each Teensy pin and the | |
pin 20: LED strip #6 wire to the LED strip, to minimize | |
pin 21: LED strip #7 high frequency ringining & noise. | |
pin 5: LED strip #8 | |
pin 15 & 16 - Connect together, but do not use | |
pin 4 - Do not use | |
pin 3 - Do not use as PWM. Normal use is ok. | |
This test is useful for checking if your LED strips work, and which | |
color config (WS2811_RGB, WS2811_GRB, etc) they require. | |
