Let's assume for now we don't have blocks that are several metres in height each smiley

Are we talking the normal stack where there can be different numbers of blocks per level? If so weight won't work and I can't see any way it can work.

Or is this some different application?

Thanks, that looks OK eh?

I've been out of electronics for a few months, been building a house, but I have a prototype board (Mega compatible) being built at present and should be getting back into it again soon when I get delivery of that.

MOSI, MOSI and SCK are all connected together, on every device connected to the bus. The master then activates a CS/SS signal for each slave when it wants to talk to that slave.

Yep, that's it. For more $ you can get it in a box as well, worth it IMO so it's protected from shorting on stuff.

Or for $85 with all cables it seems.

SAM ICE will not work with AVR AFAIK, but they do have a new debugger that does both and it's pretty cheap, can't think of the name right now though.

That's one of the key (and under-appreciated) features of that chip, it's an XMOS one way around but can easily be made into a SOWX simply by turning it 180 degrees. As to the difference in functionality, that's not documented very well though.

I've looked at XMOS a few times over the years, very interesting system.

Yes you could use an FPGA or CPLD, one hell of a learning curve though just for this app, OTOH if you wanted to get into them this would be a good first project I think.

Why indeed?

I haven't looked at the functions of those pins for ages, maybe there was a good reason but IIRC I couldn't think of one when I first saw the schematic.

If anyone knows any good impatient newbie day-one type stuff
Not me I'm afraid, I just bought some LPCXpresso boards and started tinkering, but it took longer than "one day" smiley

Actually I probably did have a blinking LED pretty quickly IIRC, it's not a turnkey as Arduino but pretty simple.

Not really, what if the legs extend while you are cruising down the highway?

I've never seen an I2C-controlled analogue MUX.

You could however use an ADC with an I2C interface, some of them have an internal MUXes for 4 or 8 inputs.

EDIT: Bugga, I didn't notice there was a page 2.

the official IDE solution is based on Eclipse
Correct, but AFAIK it uses GCC under the hood so maybe you can go retro smiley

The LPCxpresso forum is pretty good although not a patch on this one (but then what is), dunno if you can get an LPCXpresso board for the 4078 but if you can that would be a cheap way to start. They do have one 4000-series board, just can't remember which chip it uses.

I've been playing with LPCs, very nice they are. Small, cheap, 32-bits, great peripherals, good IDE,  yada yada.
