There was hope that PJRC would have gotten one up and running by now
We talked of this years ago. Ultimately I decided not to host a wiki. Maybe I didn't explain clearly. So please, remember this message as my final decision, an official PJRC wiki definitely will not happen. This was years ago and I believe it was explained on the forum thread about adding a wiki, but maybe not?
Spam was the major consideration, pretty much the deciding factor. There also will not be any other website features (also occasionally discussed) which could potentially increase the attack surface for spammers. We're already at our anti-spam effort limit.
This forum probably would not even be able to continue without your help on the spam problem. I really do appreciate all the effort you put into helping with the spam cleanup. It really does help me to be able to work more on the software, like finally added RGBW support in OctoWS2811 last night, and (hopefully) getting OctoWS2811 movie2serial working with Teensy 4 this afternoon, and if I'm really on a roll, maybe even fixing some lingering seremu partial packet flush bugs. I'm also hoping to look at Mike's FRAM work and bring it into LittleFS (had originally planned to write it from scratch).
Last week I did put a couple solid days into documentation. You might notice the schematics all have reference designators, and parts placement images were added. I added the dimension drawings, schematics and placement diagrams to the end of all the Teensy (non pins) product pages, with new photos of the boards having a ruler showing inches and cm/mm scale, where all those images are scaled to match the dimension diagrams. It's amazing how much time all that takes. In my dream world I would have enough time to fully document everything on the website, and also implement every feature everyone wants, and fix all bugs immediately. Wouldn't that be awesome?!
But life isn't perfect, and neither are wiki websites. I believe Wikipedia spent many years on their WYSIWYG editor. Spam and maintenance (like moving contributed pages into their proper places) are an ongoing reality of all wiki sites. Github is indeed geared towards expert programmers, but at least from all external appearances they have done some spectacular work on keeping spam under control. I'm envious of that.
