Inverting the output

[dougp2]

Thanks for the Library!

Would it be difficult to add an inversion feature/capability to the library? What I mean is, fading on/off seems to assume an Arduino output being driven high to light a common cathode LED. If the LED is common anode fade on/off must be reversed to show the desired effect.

Thanks!

Don't think it's worth adding it as a dedicated feature but it's already possible now. Just mirror the desired gamma table and use that table. This way the output is mirrored as well 😃

Yes, reversing the table order inverts the fade effect. Thanks! This still leaves sines.on() and sines.off() acting backwards. Is a workaround possible with #define? Or, something else I could do without modifying the library?

.on() and .off() are just shorthand for .set(0) and .set(max) so they should also flip when you use a mirrored gamma table.

Yes, it is as you say. Thanks again!
