NeoPixel/WS2812B on Trigorilla (RAMPS 1.4) Hi guys, I would like to add an RGB strip to my printer that can be controlled via Marlin. There's already a lot to find, but mostly for regular RGB strips, which use 3 pins on the board and have to be equipped with transistors. Now since Marlin has support for NeoPixel/WS2812B LEDs, that would simplify the whole thing. Power the strip externally with 5V and add only one wire for control on board, as far as I understand it. Has anyone had any experience with the Trigorilla board? And if yes, which pin would be suitable?

The DotStar LED strips from AdaFruit are a better bet, because they accept standard SPI protocol. This means that the timing of the signal to them isn't critical, also it can be done using DMA.

Thanks for the suggestion, although those do not seem to be natively supported by Marlin.]]> davidramiro RAMPS Electronics Mon, 04 Mar 2019 07:43:17 -0500 https://reprap.org/forum/read.php?219,848437,848501#msg-848501 Re: NeoPixel/WS2812B on Trigorilla (RAMPS 1.4) https://reprap.org/forum/read.php?219,848437,848501#msg-848501 dc42 RAMPS Electronics Mon, 04 Mar 2019 07:20:28 -0500 https://reprap.org/forum/read.php?219,848437,848486#msg-848486 Re: NeoPixel/WS2812B on Trigorilla (RAMPS 1.4) https://reprap.org/forum/read.php?219,848437,848486#msg-848486 davidramiro RAMPS Electronics Mon, 04 Mar 2019 05:06:39 -0500 https://reprap.org/forum/read.php?219,848437,848465#msg-848465 Re: NeoPixel/WS2812B on Trigorilla (RAMPS 1.4) https://reprap.org/forum/read.php?219,848437,848465#msg-848465
It can just barely handle 1 or 2 of them, let alone a strip.

The timing requirements are two strict and interfere with the timing requirements of printer.]]> Dust RAMPS Electronics Sun, 03 Mar 2019 20:32:31 -0500 https://reprap.org/forum/read.php?219,848437,848437#msg-848437 NeoPixel/WS2812B on Trigorilla (RAMPS 1.4) https://reprap.org/forum/read.php?219,848437,848437#msg-848437
