How to make LED display?
Building RGB LED shows is one of the most interesting development and manufacturing challenges we come across right here on Hackaday. Not just do the creators of huge displays and Light-emitting Diode cubes experience the ability requirements of operating very much LEDs, but there’s in addition the problem of getting the frame price sufficient to produce video clip. It’s a non-trivial task, but [Paul Stoffregen] has actually a fascinating option. He blogged an LED strip library that can get a handle on eight meter-long Light-emitting Diode strips that will also be used on daisy chained Teensy 3.0 microcontrollers for really huge shows.
[Paul]’s Light-emitting Diode collection works together LED strips on the basis of the WS2811 LED controller IC. These potato chips would be the common operator chips the individually controllable LED strips there is at Adafruit or countless Chinese merchants. The collection requires DMA transfer to produce photos, so if you’re seeking to develop a ginormous RGB LED show, you should collect a number of [Paul]’s Teensy 3.0 panels
[Paul] in addition developed a Processing application that takes a video clip file and transforms it into serial data for their LED strip library. You can examine aside videos for this application, library, and a 60×32 RGB LED display following the break.
