Hi , I installed 3 times FastLEDv3.1.zip from here and I dont know why its still detecting another version.

#if FASTLED_VERSION < 3001000
#error “Requires FastLED 3.1 or later; check github for latest code.”
#endif

What version of arduino are you using? There was a change in a recent version that seems to have caused problems with one of the pragmats being used.

Arduino uno

Not the hardware, what version of the arduino ide did you install?

5

just remove version check or change #error to #warning; it seems as a bug in the latest arduino ide

Ok - found the problem. Arduino 1.6.6 runs gcc in a pass to build a set of dependencies before compiling - this appears to not include header files, so FastLED.h doesn’t get included, or parsed, and FASTED_VERSION never gets defined.

Changing the line to:

#if defined(FASTED_VERSION) && (FASTED_VERSION < 3001000)

will also fix the problem while retaining the version check.

Thank you for helping, I will try and I will reply.

What’s going to be a little bit trickier to fix/work around is why arduino 1.6.6 doesn’t appear to generate prototypes anymore for .ino files.

Ah - that problem (which I don’t think you’re hitting here) is https://github.com/arduino/arduino-builder/issues/68

I dont think clearly what i have to do.
Is that code i have to change ? #define FASTLED_VERSION 3001000
#ifndef FASTLED_INTERNAL
#warning FastLED version 3.001.000 (Not really a warning, just telling you here.)
#endif
Thank you
