Really? Corsair doesn't connect the power of any of their led's (fans or strips) to anything other than 5V SATA from the power supply. Please don't try this at home kids. My MSI motherboard even has a header to power led's labeled LED and I would be afraid to connect it. IMMHO, all led strips including fans should be powered from somewhere other than your motherboard.

I believe the arduino IDE is required, there is a pull down for Visual Micro (No IDE) but I haven't used it. But once you setup the arduino IDE you'll never even know it's there while you're in VS. The serial monitor is much better along with the editing and other improvements provided by VS. You know a whole lot more about arduino than I do, so I'll be happy to follow your lead on USB-HID vs or in addition to a serial port. Let me know if I can help.

Thanks man, I'll try to push a branch in the morning. Excessive use of constexpr from C++11 (which at least the lasted arduino compiler supports, not sure of previous releases) allowed some nice compile time magic for static array sizing keeping the diffs to the master branch minimal. Still very early on, not happy with memory usage and still things I can't explain but that may be the nature of how I implemented the changes. I'll grab your latest from github so the merge won't be too bad in the future. Also, sortry about your code loss. Have you tried using VS with vMicro under windows? Made development a lot easier than arduino IDE and makes it easy to restore unsaved changes in case of a crash. @kubdotnet your software has made testing and experimentation way better. smarter, faster. Have you thought about making it a VS extension? If nothing else you could share the com port so changes to firmware don't require shutting down the LedControllerEngine to upload firmware changes. Maybe just my current workflow and wouldn't be as useful in the future.

c Yup, tried that right after I last posted. (and then fell asleep :zzzzzzzz:) All the fans do light up. Here's what I've found out. LL120 info The center leds are 1-4 and outer are 5-16. The leds on the outer loop are sequenced differently, from the front the 1st led is at 10 o'clock, on the HD120's the 1st led is at 2 o'clock. The first attachment shows the difference, red is the 1st led, green 2nd, blue 3rd and yellow 4th. Yeah the pic's bad. (unfortunately the transition from red to green is more yellow than the yellow color) Both fans increment counter clockwise. So short of dealing with the center loop and sides/quarters it's not too bad of a change. 'course the devil's in the details. I've played with some code to implement fan types to allow for number of led's per fan, offset of outer ring and identifying the type at run time. Hope you don't mind Charixfox. It's really prototype as a proof of concept but the second pic shows it's sort of working. I'll keep going as long as it's ok, I don't want to step on any toes. A very nice code base to work with, good job Charixfox. Lemme know if I should keep going..

Hey, wow a lot going on here. Downloaded your app kubdotnet, looks really good (nice icon too). Haven't gotten a chance to run it on my system that has fans and lights but the interface is way cool, let me know if there's anything I can do to help. My LL120's came in this week and I hooked 3 up tonight, as kinda expected they're in serial and my last fan had no lights since the 4 new center lights of each fan took up 12 lights replacing the last fan. Seems like 16 leds/fan would require a fair amount of incompatible changes to the controller firmware, also tried to imagine how 12 fans (6 outer and 6 inner) would change things. It still wasn't pretty since there would be 6 fans with 12 lights and 6 with 4 lights. I dunno, let me know if you want to support LL120's charixfox. Yeah, I know they're lesser fans but with 6 should I even care? ;) Once again, good stuff here. Thanks all.

Been lurking in here for a while now. Learned a little about LED's from this thread, a little about HD120's (ok a lot about HD120's) and even more about arduino. Thanks for all your efforts charixfox. Corsair recently released LL series fans that look pretty cool with the extra 4 leds in the center. Might not be too much effort if the extra 4 lights were addressed as an additional loop per fan as Corsair seems to have done. Even though I just spent a fair amount of money and effort getting six HD fans working, I'll most likely end up grabbing the LL fans soon. Do you think you might add support for these in the future? If there's anything I could do, if you choose to enhance the firmware. I'd be glad to help in anyway I could. Thanks again for a great thread.
