I think we may need to up the baud rate on this thread it's getting so long.
Anyone know about NMEA 2000?

It is built on canbus and rs232 is an absolute no-no there...

Yes, this is *SO* representative of my impression of you and how you act. Why would you object to anyone pointing out that a shift would be more efficient or more clear than a divide? If anyone has suggestions on improvements for you, why not just take them and be happy, or ignore them and still be happy?
You don't have to treat everything as a personal attack on you, just because someone says something else than "Oh, what a nice little project", but instead says "if you do like this or that, it will work better".
If someone want to help you improve your design for free, why be so negative about it. It's like it is your baby and no one can touch it, or what? No one is forcing you to take the suggestions either, but you don't need to start arguing about them either, if you are not prepared to take a discussion on the subject.
I am installing a through hull DST800 transducer with a fairing block... If someone professional installer had comments about how to do that and material choice, I would be more than happy to get them. I thought that was the very purpose of the forum, to be able to discuss these things, but it seems this forum should only be used to pat each other on the shoulder and say "what a nice job you have done"...

Well when the electronic attack dog up their claimed that I hadn't written the code for the soft UART, I was going to post a whole load of C source.
But then I had a horrible premonition. That would just start the whole process again from the software engineers barking at me...'You should have done a shift instead of a divide' etc.
Maybe I should post details of the plastic box it sits in so the industrial designers can come in and have a chew.
An option for avoiding code is programming the soft UART in a visual language such as Statecharts. If I dig back a few years I could probably find you a program I wrote that will translate a Statemate model of the system into bytecode for a virtual machine that implements the model. All you would need to do then is implement the virtual machine on the pic. Obviously it won't work properly but it will give you an authentic Airbus feel.

Where does a discussion become an argument? He's worked for many years writing embedded code. I'd prefer a blue development board myself rather than a red one.

And? What is the difference if you call it a discussion or an argument? I completely fail to follow your meaning here...

Here's a small plastic box I was intending using. I can buy it from RS for £2.32...
Any industrial designers out there who want to have a rabid chew?
Just to clear any confusion, it comes in 3 colours and sizes, each displayed above, but I only need one. Otherwise they are basically the same. I was intending choosing the centre one, but I expect professional marketing people will probably disagree.

It was not less than 3 boxes afaics...

It's just a 4 dimensional box that's all. If you rotate it right then it changes colour and gets longer.

So just go back to page 1 and 2 of this thread and see when/how/if the discussion turned into an argument.

but there's no difference between an argument and a discussion.

Once again people here turn into ridiculous mode... What's wrong with you ppl...

OK, so if there is no difference, why did you want to know when it turned from one into another and why did you just define a difference?

We could debate it.

Do you think that would clash with the red board? Any fashion designers about?

I would add a blue status LED, and house it in a transparent box or embed it in clear epoxy.

So this Jewish mother was attending her son's Passing-Out-Parade, and noticed that the troops were not all in step.
"Oy vey", she exclaimed, "just look - and they're all out of step already ....
... except my boy."

That would go very nicely with my tablecloth and cushions...

Anyway, to get back on track.....
You'll be needing a splitter to distribute your multiplexed signal.
Here's one I knocked up:
Fully functioning 2 port splitter with universal connectivity option. It uses a PIC16F84, but only because it was already stuck to the insulating tape. I should be able to knock them out for about £232 each. Let me know how many you want, and we can work out a deal.
