Whilst I haven't bought one (yet) I think that separate on/off commands are essential to get a group of equipment to behave the way you want. Without this, if any one piece of equipment is in a different state to the others, for whatever reason, then it needs a physical press to get it back in sync. With discrete on/off codes all the equipment gets cleanly set to the same state

Only one display was faulty; the Maplin, I mean Muplin one

I am currently eyeing the OLED offerings as they seem to be way nicer than LCD with LED backlight...

Might have to get one for the nice case I am getting...

So 4 more for me... I think 6 would push the processor to hard too - unless the expansion board has only board processing power.

This project has been on the backburner for some time but now I've
started it up. Ran in to a problem rigth away. The display pin connections
wasn't named the same way so now I'm sure I'm putting it together the rigth
way.

Could someone tell me where pin 1,2 and 5 would connect to Najda ?

Seems that the display only has one "gnd" as well. Would both pin 1 and 16 connect to pin 3 at the display?
I found this helpful in mapping;

The white on black displayfrom Polish seller, I just fitted was pin for pin the same as Najda.
The Maplin one had pin 15 and 16 as 1 and 2, and the rest following on from there.

As Nick says; you have found other mixes are out there.
VC and VA are new to me.

Steve,
- Maybe if you have two systems you want to compare or have them in two different rooms, or if you have more than 2 channels ?

Charpak
- May you please explain what is the mix of IIR and FIR ?
- What is the limiting factor you are experimenting now for >># of taps CPU or Memory ?)
- Is it (will it be) possible to upgrade memory on the MB itself or on the expansion board, or add a second processing unit ?
- Custom IIR, you mean filter types that are not butterworth or LR ?

BR

Alright - but the deal is 2 or 6, 4 is not an option

In short: 2 more outputs, we could make this happen shortly.
6 more outputs would take much (much much actually) longer.

Easy then for me.
Two is perfect.
10 outputs is more than
any? other dsp dcx I believe
and meets / exceeds the needs
of most.
If you have 2 rooms, buy another
Najda and chain to solve the problem elegantly.

6 might be nice one day as I may
try an injection channel, but not right now. If I do it could be analogue for the time being.
Regards
Steve
