[QUOTE="matthew henry, post: 1196338, member: 159933"] [FONT=Roboto][COLOR=rgb(20, 20, 20)]I was going to create a new post but I guess this is a better place for this question. I have a 50" tv that will be using APA102 LEDs with. 60 per Meter. I think in the end it will come up to around 170 to 200 LEDs. The powering unit will be a 20 amp 5v I have already ordered a Raspberry Pi 3 (all my content will go through OSMC or OpenElec) and I know it has the SPI pins so it should be able to run the APA102 LEDs by itself without anything. My issue is regarding the FPS. I really want these effects to be seamless so I kind of want it as close to realtime as possible (im not using any screen grabber just straight from rpi) (examples) [MEDIA=youtube]-ki0HX8lMBk[/MEDIA] [MEDIA=youtube]GWSxVuRO-vk[/MEDIA] This video shows what I am trying to achieve. For this type of speed and the amount of LEDs do I need a 74HCT chip level shifter. Im not amazing at the solder gun so im not sure how well that would work. There is also the arduino route so that the RPI doesnt have to do the work. Is this way faster or slower. If I went with this route with arduino would be best I could also go the teensy 3.2 with the octows2811 adapter (is this overkill) [B]This wiring seems the easiest[/B] [B]So I guess my real question is to control around 200 APA102 LEDs with relatively seamless operation is the RPI 3 Alone sufficient.[/B] [B]Do I need to add a 74HCT chip level shifter?[/B] [B]Do I need to step up to an Arduino?[/B] [B]Do I need to go the Teensy 3.2 Route?[/B][/COLOR][/FONT] [/QUOTE]
