Prop 2 plans? Who else is planning a project around the prop 2?

Hi all, i was just thinking about my current weather station, that is entirely of one-wire devices, and how i would like to redesign the whole thing to use the new prop 2 when it comes out.the main reason is because the prop 2 will have analog i/o. i like the one-wire approach, don't get me wrong, but it can be kinda troublesome at times. my plans are to use all analog output based sensors with the prop 2 doing all the processing of data and outputting that data into a serial stream to be used by software on a connected pc and to have a video out of the prop 2 to show a real-time screen of all parameters.
I'm just curious who else has plans for the new features and willing to share with the rest of us.:idea:

It will be quite nice to have integrated ADCs, so I can remove the MCP3008s I have (I have 3 of them on one PCB), and get faster sampling directly on the Prop.
"Morpheus 2" will be Propeller 2 based :-) and I am considering several other products.
is almost ready to go. We feel that the system will actually cost
less than the dual Prop 1 configuration that we use now.

Better do a little more practicing using .4 mm spacing.
Russ ...
Same for me. Use what we offer for the best results.

I know, I'm crazy.
Naturally some issues arrise, but if the upscale from prop1 to prop2 isn't too painful, people will use the prop2 just because.
(except for DIP projects)
I have no plans for prop2 because I have not even reached my personal limits on what the prop 1 can do.
(except for my desire to make a spdif mixer out of the prop)
The prop1 has not even made its world tour yet. Its just beginning to grow in popularity.
I'm actually awaiting for Prop 2 to be released and Prop 2 ProtoBoard to be available. When Prop 1 Protoboards came out I got a 6-pack. Will start with a single one when the Prop 2 is available. I've not yet done all I want with the original ProtoBoards, and have some spares still. Great starting format for many projects.
In reality though, I think it is good to think about both props in parallel. By the time the prop II gets here, I should have a pretty good handle on what I want to do with it. The tranistion should be smooth.

P2 will also require separate 3v3 and 1v8 power supplies for the I/O and core, respectively. That's what you pay for 160 MHz and the other goodies.
Also, as we all know, P2 will only be available in SMT packages. I am not horribly bothered by this myself but there is a place in the world for stuff old people and kids can see.
So I wouldn't count P1 out yet. I suspect P1 will remain a good choice for a lot of applications even though P2 exists. And should P1.5 ever appear, with P1 process but 64 I/O, that's a whole nother market.
Ha! Yes I have. But I like my Z80's to come in DIP packages. If I'm going to spend time getting familiar with yet another mcu it's going to be something more interesting. The "chip that shall remain nameless" for example.
I'm glad Zilog does not use that old logo any more or they might be wanting to have words with me. (Is parody a fair defence against Trade Mark abuse charges?)

It could run a lot faster in a newer device.
I'd still love to see the Prop-1B (also known as the Prop 1.5), it's a Prop 1 with 64 I/O lines. It's already enabled in the code, just need the chip! This would solve a number of problems (rather than being creative with design to juggle a pin shortage) and would really enhance the Prop's capability. I'd love to find out if that's still on the cards and whether we'll ever eventually see it. But then again, there are coding advantages of connecting 2 or more props together (haven't done it, but I can see the advantages).
Stop it now guys, if I wanted to do all of that I would have done all of that. Newer faster Z80's and Z80's in FPGA's is kind of dull because, well, it's been done. The Prop was/is new territory to investigate. I'm glad I went the way I did. Don't forget the whole 8080/Z80 emulation thing was initially just an exercise for me by which to learn what a Prop can do and get into Spin/PASM. It was either to be the emulation or the Prop as I/O video peripheral to a real Z80 as done now by the N8VEM group.
What I really wanted to do with the Prop at the time I discovered it was to create a digital crossover for loudspeaker systems. I have a pet algorithm that implements the required filters, it's basically an "emulation" of the analog filters used in an active crossover from the Rane Corporation. See attachment. This algorithm has been working on a PC sound system very successfully for years. I'd just like to see it in a self contained little box.
I'm still not sure the Pro has the horse power or I/O capability for that crossover but I suspect the Pro II will.
Which one?. I want at least stereo in, stereo out split to bas, mid, tweeter channels. normal 16 bit 44K sampling. I want to have a little screen showing the cut off frequencies. and allowing adjustments. Perhaps also have it adjustable via USB.
Looks like the Prop II would be perfect. Else I'm leaning toward the "chip that shall remain nameless"
It's building a good A/D and D/A setup that is the stumbling block for me.

It's just under $60.
Remind me to post a link to the Prop 2 demo board when it comes up.
Do you know something about a Demo board for the Prop II that we don't ?
Whatever CPU I'd be happy for any kind of board that provided enough analog audi channels and did not cost an arm and a leg.
