Prop BOE

Hi everybody. I have no experience with the Prop so bear with me.· I was looking into the propeller for a little ways down the road (or at least until I can find some room in my budget).· I was wondering if there was any·Parallax plans·for making something for the prop like the stamp's boe or SX's tech board?· The protoboard is about what I am looking for, but I like the breadboard on the boe.· The prop demo board also looks cool, but many of the IOs are tied up with stuff that I wouldn't need.· What would be the best place to start with?· Here is what I am looking for:
This probably has been discussed before so other threads help too (I couldn't find anything)
Thank You very much, Happy Coding.

- Solderless, I like to change things constantly and I don't have experience with it anyway
- Many IOs, I plan to make a bot that has·a·lot·sensors.
- Video plug for debuging (I have heard that you need one?) I could solder this, are there thru hole ones?
- Way to learn SPIN/Assembly (book or soemthing?)
- Cost effective
This probably has been discussed before so other threads help too (I couldn't find anything)
Thank You very much, Happy Coding.

You'll get the best of both worlds. You can have keyboard / mouse / Composite Video / Audio / SD card access / Servo Connectors or direct access to IO pins when you desire. But if you need more servo's or IO pin access, you can unplug the modules you don't need, and plug in more IO/Servo modules.
And you don't have to buy modules you'll never use, it's ala'carte! or if you find a need for features in the future, just order that one module that you'd like to add.
Most of the modules can be used with Parallax's Protoboard also, with a simple addition of a 20 pin male dual row header (which I provide for free by request) See The Propeller Cookbook (which is mirrored on my website also) for directions for this modification.
There are a few more modules that I'm designing right now. I'm quite excited about them, and I think other's will be exited as well when they are released.
These modules are kits and do require soldering, but contact me if you are uncomfortable with soldering and I could assemble them for you before shipping.
I don't mean to hijack this thread with a blatant advertisement, but I thought my product sounded like it fits your needs perfectly

Brian, I don't take your post to be a blatant advertisement. I think that is more or less what I am looking for. I will have to tally up the total cost for all the parts. I like the buy-what-you-need idea.
Thank you for your ideas!
PS I'm still open to more.

Not that you should but *someone* should.

Stay tuned
I like the PEK but breadboards are harder to mount/bulkier for a bot. There are some labs to do with the kit on these forums right?
I have one of the BOE's breadboards that I bought with my last order would it fit on the protoboard (without mounting it on top of the chip)?
Thanks for the heads up deSilva. Do we have a time estimate?
If you are putting together a kit for the product, my opinion would be to have everything necessay to use the propeller including the manual. Just so you know.
What is the best documentation to learn from?· What did you guys/girls learn from?
BTW I appreciate your help.

- The Propeller Manual is really good : Start with Chapter 3!
- Work through the Educational Examples; even if you find some of the things dull, you will get A LOT of background information!
Everyone else,·Is it very helpful?

Nevertheles it IS important to look things up from time to time, especially for machine language in chapter 5. Note there is also a (small) Supplement/Errata for the Manual!!
When you want to code in machine language, I should - of course - also recommend my Tutorial; it can be found through one of the sticky threads. I shall update it soon, and then the thread will pop up again
I assume you mean the "General IO / Servo" module. The female header on the far right of the picture is wired directly to the 8 IO pins in that Socket. If it's plugged into Socket A on the main board, it has access to P0-P7, Socket B is P8-P15 etc etc
The 3x8 grid of male headers provides access to the same 8 IO pins, but with a current limiting resistor. You also get 5VDC and GND, these 8 rows of 3 pin headers are for plugging devices such as Servos or Ping sensors right in.
Most measure approx 1.25"x2" there are some exceptions, such as the SD card adapter.

Brian when I said: "Brian, can you tell/show me what the pins of the headers are linked to?" what I meant was a picture of the header with the pins labeled Ground, +5V, 3.3V,·pin 1, pin 2·and so on.· Or if you can describe it instead that would be fine two.· Thank you

the thing I do like about the demo board is that a lot of the spin objects are written for it, so you don't have to convert any pins callouts. it also allows you to very quickly see what the prop is capable of. I had my Compass displayed on my TV in about 5 minutes. and listening to "Singing Seven" a minute later.
I your looking to build a bot or other project I would buy: 2 proto boards 1 accessory kit and the manual. that will give you the best of both worlds, hard copy of the manual and online docs. buying 2 proto boards would give you one to build your first project and one to learn on. hope that helps...
with all seriousness.... if you want to borrow my demo board on a you break it you buy it basis, let me know. perhaps a good faith deposit wouldn't be a bad idea also.. but seriously... let me know. I'm going to buy a couple proto boards soon.

Also, It's pretty easy to make up small boards for things like composite video that just plug into the I/O pin strips (also see below).

Here's a illustration of what each "Socket" is composed of. 2 pins that are omitted in the diagram are the I2C lines SDA and SCL, they are used on boot up to read the program from EEPROM, after which you can use these lines to interface all sorts of devices.
A 20 wire Ribbon cable with the appropriate plug can be used to "roll your own" devices that can be plugged and unplugged with ease.
One other option is to use a Protoboard, and modify it by adding 1 or more headers, as explained in the Propeller Cookbook, which you can download here --->
ucontroller.com/indextutorials.html
see pages 14-15, it's a very simple modification and then you can plug SpinStudio modules right into your Proto Board. It's an easy way to add features to a Protoboard.

Dgswaner, thank you for the offer and suggestions.· I like your 2 protoboard and a manual idea, but I will pass up the demoboard rental.· I seemed to be inclined to messing things up and $130·is a lot for a board.· The propeller cookbook looks awesome.· I can guarantee I will try most of those things when I get a prop.· Is there no code for it or did I miss it?
Thank you for all your great ideas. So many options.· Keep the ideas coming.
EDIT: What is the RCA jack called (sounds dumb but·I can't find it)·/ does anyone know the part #? (preferably mouser)· Thanks

I wasn't going to release this until the next Cookbook, but with all the "club" prep going on this weekend,
I doubt I'll get around to posting an update till next weekend. Here's the completed cookbook entries
for converting your Protoboards to SpinStudio. (Brian, if you want to post this until I get the next release
completed, feel free)
