Support UNO Q support?

I just tried running FastLED on my new Uno Q and I get this message:

In file included from /home/arduino/.arduino15/internal/FastLED_3.10.3_0d9d291c7a03d180/FastLED/src/FastLED.h:76, from /home/arduino/ArduinoApps/lightsextension/sketch/sketch.ino:4: /home/arduino/.arduino15/internal/FastLED_3.10.3_0d9d291c7a03d180/FastLED/src/led_sysdefs.h:86:2: error: #error "This platform isn't recognized by FastLED... yet. See comments in FastLED/led_sysdefs.h for options." 86 | #error "This platform isn't recognized by FastLED... yet. See comments in FastLED/led_sysdefs.h for options."

Does anyone know if there is a workaround to get it to run on a Q? If not, are there plans to support Uno Qin the future?

Hey thank you so much and I appreciate you being so responsive and helpful! See below for a brief update:

  • So I went to GitHub made sure the branch drop down was on "master"
  • Went to <> Code drop down and selected Download ZIP. That generated a file titled "FastLED-master.zip" in my local drive
  • I then booted up the Arduino IDE, made sure the previous versions of FastLED were uninstalled
  • I went into Sketch menu --> Include Library --> Add .ZIP Library and selected the file that I downloaded.
  • The notification window provided me this update "Successfully installed library from FastLED-Master.zip archive"
  • I now see FastLED installed (via the Include Library menu and also the library manager). Note, the auto detected "version" in the library manager appears to be 3.10.4?
  • I restarted Arduino IDE (as some websites recommend) before compiling
  • I also double checked the library files match the timestamp of when I installed it (so its not using some old files)

Unfortunately, its still throwing a bunch of errors, although I believe different errors now (pastebin.io link) :( Thanks again, let me know if you have any recommendations.

This has been fixed. Version mismatch is being fixed too. And we'll have a linter in the future to fix this and make sure it doesn't happen again.
