Hello

I finally got around to testing the serial opcodes on windows,
it works fine, excellent!

Now, I would like to receive values with a higher resolutoion than 8
bits from the arduino.
How would I go about to do this ?
I could think of combining 2 bytes into a 16 bit value, and use a (0
or 32767) value as a "delimiter value" but how should I ensure that I
synchronize correctly (read the correct 2 bytes together)?
matt?

I cannot convey how much that is a relief to me!

You have two potential routes.

1: Take two 8-bit quantities and construcyt a 16bit (or if preferred 4
bytes to a 32bit thing)

2: Use the MIDI hack where bottom 7 bits are data and if tne top bit is
set expect a further 7 bits,... and repeat,  This gives tighter coding if
you expect numbers to be small mostly, but at the cost of reconstruction
and coding

Thanks a lot,
and it seems reasonable for me to do the 7-bit route as the values I'm
trying to transmit are actually 12 bit.
all good

You will have to think about negative numbers.  is 01111111 really -1
(i.e. sign extended) if is it really 127.  Might be easiest to treat as
sign extending -- but that depends on where you are expecting to transmit
negative numbers

Oh, that'll be fine, the values are unipolar at this stage.

When this is all done, let us hear your bridge sing, please. Jpff will be particularly pleased I'm sure.

Yes, of course :-) I'm looking forward to hear what you think of it.
I will release a composed piece based on recorded sounds from the
bridge late December or early January.

There might be a smaller scale "pilot" project on a bridge in
Trondheim in September 2012,
and I hope to finish the large bridge project by August 2013.
