Is there any concrete reason for using 11 leds at led-rings? Instead of 16 (the max.) or 10 (for scale purposes)??

Thanks in advance

ehm, no? Make it as big as you like. If the diameter of your knobs is small, you use less, and if it’s big, you use more. I (am going to) use 12 i think.

ok, ok, just asking because a lot of designs that I see around here use a 11 led configuration.

I guess I’d use an odd number of LEDs, so some sort of middle position could be displayed…

Well, i use an even number so if the enc is in the exact middle no leds are lit.

I think the most important reason you frequently see 11 leds is that almost every FPD designer used Thorstens original design for the MB16e, which had 11 leds per encoder, and cut&paste with that for their own designs.

Is it hard to implement more than 11 LED’s? If it requires changes in the code, then that sounds a bit deep for me at the moment.

Hi guys,

If your’re building mbhp projects for mackie/logic controller emulation you are limited to 11 leds because of Mackie’s protocol and not mbhp hardare limitations.

If you’re building MB16E projects or using its encoder ring source code in your own designs than you can have 16 leds by modifying the display pattern code. Its very simple to do so.

Peace

Thanks Frank, nice answer.

good FAQ material, IMO

Minimum value 0, max 10 logical steps…11

It may be a digital system but we come from an analogue world.

Lol, thanks you all for the answers.. Let’s put eleven leds!
