Just upgraded SimHub to the latest version from an early 2019 one and found out of the new LED editor.
All the new features are great but I can't see why I am no longer allowed to set the brightness below 4%.
Before I used to keep it at 1% and it was already bright enough because I play in the dark and any other value would be enough for my WS2812b to flash into my eyes.
I'm not joking even 4% brightness isn't usable at all. Can we please revert the brightness scale to a standard 1-100%? (or even 0.5 would be appreciated)
@brugja
Not entirely sure what feature you're referring to, would you please ELI5? 🙂
Any word from the dev?
@Wotever ?
Hi ! The new computation system requires a minimum brightness to be accurate, I restricted it to be sure it would give correct results, when going lower to 4% some colours would simply be rounded to 0 and be off, which was definitely a big issue (it was already the case before though) that's why I added this restriction in order to avoid going in this "troubles" range where coulours would randomly work.
Thank you for your response.
So there's really no way to get around it? Not even at my own risk?
I've never had any sort of issue while using them at 1%. And I really can't use them any higher than that because playing in the dark makes it really impossible. It's really either 1% or I won't be able to use all the new exciting features.
I've modified it a bit for the next release 😉 for "pure colours", blue, red, green it works fine indeed, but more complex colours will reveal the issues 😉

Hello Wotever, thank you for creating Simhub!
(I hope it generates enough monies for you to live on!)
That said, I have had the same issue as the OP:
When racing in darkness the LED's are simply to bright.
After I exported the sketch that was supposed to program my arduino I modified it a bit, by issueing:
Adafruit_neopixel.setbrightness(20);
After that I could set the slider to 20 or even 30%, and it worked beautifully -for all colours- without artefacts.
I wonder: Are you using the same algorithm Adafruit is using?
If not, why not?
else, what - if any- is your reasoning for using a different algorithm?
Cheers and best regards.
@torgbornottorgb Hi, are you able to give more information on how to do this? I've noticed that there are artefacts and colour reproduction issues below 20% brightness in Simhub, which isn't ideal. At 15% brightness, when stepping up through my gradient, I see red on the next LED before stepping up again and it showing green like it should.
10%-15% brightness is what I'm aiming for as anything higher is just too bright for my use case.
@torgbornottorgb Hi, are you able to give more information on how to do this?
No.
You just have to alter the software that gets shot into your arduino.
C:\Program Files (x86)\SimHub\_Addons\Arduino\DisplayClientV2\DisplayClientV2.ino
And make sure it never gets reprogrammed again.
Have fun!
