Shame I cannot read any of the data on the pics.

How many I/O pins on the TruboProp? Looks like a 100pin package so maybe >64, say 80??? http://forums.parallax.com/images/smilies/smile.gif

Cluso99: Another thread here had an image posted by Beau (I think) showing the 100 pin setup. It showed only 64 i/o pins. It has seperate power and ground pins for each set of 8 i/o pins so that accounts from 16 pins, then it has 8 more power and ground pairs for the core. So that's 96, leaving 4 more for the crystal, boe, and reset.

Edit: found the link to the image, it was posted by Beau. http://forums.parallax.com/attachment.php?attachmentid=67545

Damn... I thought we may be getting a few more I/Os. Well, you can always dream, and then be thankful with what you get.

Yes, I recall that pinout now - had a senior moment when I though it had fewer pins before, even tho' I knew about the power for the pin groups, etc.

I just remembered a couple more things... Yes, it was a 100-pin package with 25 pins on a side. 4 pins on each side for core and i/o supply. Crystal pins on one corner and Res/ and Boe on the other corner.

Also, one bit of the pin config register decided if the digital output was done the usual way or locked to the main clock. The later mode overcomes the slight cog to cog timing variation so that all pins can toggle at exactly the same time. I think he said this was useful for SDRAM interface apps.

Awesome!

What a great time. It was neat finally getting to put a face with screen names on the forum. Sorry, I can’t post any pictures was too busy talking and looking at everyone else’s projects.

I would personally like to think Oldbitcolletor for organizing the event and all his helpers who set up and took down everything. I also want to thank all the sponsors and vendors for taking the time and expense to come to the event. Your generosity made for a great day and I can’t wait to next year and if all goes well I plan to be at UPENE 2010.

So much inspiration so little time!

I will try to post some pictures later today.·

But before·I do that, let me paint a picture for you regarding Mike's Turing machine and Nickle-o-matic.· If you have never seen them - you must make time to do so.· I don't have the links to the videos so hopefully someone can post them.· Anyway, back to the picture....

Ken and Chip's kids were there along with a few other young folks.· I would bet they spent the better part of 4 hours watching those machines run. Putting a coin in the machine, watching the nickles get printed - collecting the different ones the machine makes.· At one point, the youngest boy (not sure if he was Chip's or Ken's) was standing on a chair behind the machine reaching up as far as he could to load the blank nickles into the nickle-o-matic - if someone got a picture of that please post it - it was too darn cute!

One of the other kids was handling the raffle at the end of the evening - another enjoyable experience.· While the prizes were great, the kid (sorry I just couldn't catch all the names) was a star in the making doing the raffle.

Just wanted to thank everyone from Parallax and Gadget Gangster for the Expo!
Door prize was very generous, and I was hopefully inspired to start another project with my new board.

I am thinking of extending my energy meter that I made to monitor my house's electric consumption. After seeing the "Nickel O Matic" now I'm dreaming of some sort of giant mechanical and very visual way to display wattage consumption.

Any ideas? I first thought maybe a servo with a stick for an analog meter but that's pretty simple and unexciting.

This was my first Expo or Parallax event of any kind, and it was fantastic. I have worked with BS2 stamps for a few years with hobby robotics, and some of the Stamps in Class products, which I really think are great. I have never felt like taking the plunge into the Propeller for the limited stuff I do. I live only 80 miles from Ottawa, IL so I could not resist. Meeting with Ken Gracey, and Chip Gracey, and listening to the tech presentations and all the great handouts. It was a great time, the folks from Parallax are just as nice in person as they seemed to be as a customer on the web and the phone the last 6 years or so I have dealt with them. And that is rare, and getting rarer in my opinion! Great enthusiasm with presenters; enjoyed Mike Davey's two cool projects, talked to Tony B. about the 3 Bots he brought and learned some good ideas. I had to leave after about 3 hours, but overall a great experience.

Just one other Prop2 note: I believe Chips said that all I/O is now being designed for 3.3 V.

I believe previous talks suggested that each group of 8 could be at any voltage 1.8 to 5.0.

Right... Chip also noted that the PropII will use a millimeter (microgram?) more current. So, for some power sensitive applications, the Prop1 will still be the choice:)

Chip also expressed an interest in hydraulic actuators... so if any of you have been trying to figure out what to do next.... a project with cheap little Propcentric hydraulic actuators would be welcome:)

The analog stuff works best at 3.3V. At lower voltages things slow down too much to be very useful, as there's inadequate bias.

Sapieha,

My fault. The original intention was to have live streaming video. I was re-assured locally that this would be no problem... well it was a problem that there simply wasn't time to fix. By the time we found out... it was already too late. I missed the first part of Chip's presentation, because my son decided it was time to go home. The last half... which I did see was very similar to the published materials in the webcasts and prior UPEs.

I think it would be ideal to have two way communications from various Propeller hot spots around the world... and I am going to try to make sure that is possible and happens at the next UPEC.

We are almost at the point where we need two rooms... so having video available in secondary rooms will also be helpful.

I spent about half of his presentation listening with interest, and the other half of it being amazed that I understood quite a bit of what he was talking about.
It would have been 100% Greek to me a year ago, but last Saturday it made perfect sense - and I even knew what most of the acronyms he used stood for. And the stuff I didn't understand, I think I could figure out if I put my mind to it.

I've paid a LOT of tuition in my lifetime, and I recognize a valuable free education when I see one. Don't tell them this, but that $100 Prop education kit is worth about $4000. http://forums.parallax.com/images/smilies/smile.gif

My son could not wait to get home and dig back into the education kit. Since he is autistic... his time to integration is anyone's guess. He certainly doesn't understand what he is reading in the way that you or I understand it. But he loves to read the book... there is a rhythm and reason to it that makes sense to his brain. He will eventually understand most of it... his ability to abstract has a binary quality.· He can go along not understanding the simplest things for the longest time... and then all of a sudden he understands it all. In school...he went from 4th grade math skills to 12 grade math skills in one year... because he took a computerized course at the local college (IVCC).

To me, the education kit is priceless.

Chip's pin modes open up a whole lot of possiblilities... If I understood it right, the HHH and LLL values define the source impedance or current source level for high and low states. You can have high be a 10kOhm source and low be a 10uA sink, if you wanted...

I'm still getting a handle on it myself... I think it means that you don't need external resistors for a lot of things... I think that one could do an I2C bus without external resistors now...

With Prop1, when you set a pin high the pin voltage is actually 3.3 Volts, or something is terribly wrong... But now, if you define a 10kOhm source impedance and output a 1, then the input could be 0 if something else loads it down...

I was just thinking about Chip's talk, the part where he discussed a new SDRAM mode for the pins (I'm not sure I understood what he meant) and how he was thinking about using SDRAM for video display, but the problem was that there was not much blanking time to update the display.

Well, I just wanted to say that I've looked into this too and I think the best solution is to use two SDRAM chips, to double buffer the display... Show one, while writing the other. Also, I think it's possible to copy one SDRAM to the other during one frame for cases where only small changes are needed...

I've read that PC video cards don't use dual-port memory any more, they just use a lot of regular memory...

Just one other thought... There are now 80 I/O pins for Prop2. I was thinking that all the functions included in each pin are kinda overkill for a lot of things I have in mind and just plain digital I/O would be fine.

But, it just occurred to me that you could use the various source impedances and a little external logic to decode the source impedance from 1 pin into a couple digital I/O... Creating two digital outputs from 1 pin... At least, I think that would work...

Wow 80 pins? Pretty exciting!
I saw the references to SDRAM and was hoping more details of that would emerge.
With 80 pins one could hook up practically anything at 3.3V ... So many possibilities :)
Embedded Linux on Prop2 could really happen and actually be useful !

Cheers :)

May the road rise to meet you; may the sun shine on your back.
May you create something useful, even if it's just a hack.

Dave,
The UPEC was in Ottawa? Canada?
Smock. I'm just across the river... I did not see any announcement.......missed it... darn...

Hey, I might ask you to be my teacher... http://forums.parallax.com/images/smilies/wink.gif no much anywhere else http://forums.parallax.com/images/smilies/mad.gif

You live in Ottawa?, if so, is there a group or some sort, get together..?

Rayman,
PC video cards haven't used "dual port" memory in a long time. The higher end cards just have really wide busses to the memory (256bit to 512bit), and that memory is GDDR3-5 clocked really high. The top end cards have 150-200GB/s memory bandwidth. Considering that a 2560x1600x32bit frame buffer (one of the largest PC modes available) is only ~16MB, those top cards could read or write the full frame buffer 10000 to 13333 times per second (if they were doing nothing else).

Anyway, I'm really looking forward to pushing the video capabilities of the Prop2. Especially with the texture mapping stuff. I'll be happy if I can get a 720p display going at a reasonable refresh rate on the Prop2, I suspect it'll be capable of more than that though.
