Data flow with OctoWS Large LED arrays consume considerable power. For a bi-directional part that has registers in both directions take a look at the 74HCT Start an update of the LEDs. Please use caution when viewing large numbers of LEDs at close distance. The number of LEDs connected to each individual Teensy 3. Actual display on LEDs view large original image.

This function returns within 2 microseconds. The size of portion of the video this Teensy should display. When using datasheft one Teensy, set these to 0, 0.

Appropriate wiring should be used. A diffusing material in front the LEDs is usually a good idea. This PWM pin and the timer must not be used.

Fewer or shorter strips may be used, with addressing described below. Any number of Teensy boards may be used to support large LED arrays. When using only one Teensy, set these to If called while a previous update is running, this function waits for previous update to complete and then starts a new update.

You can only create a single object, but it must be created with these parameters: The memory used for display data. For a latching function take a look at the 74HCT The number of LEDs connected to each pin, or maximum number if different on each pin.
