View Full Version : Propeller Newbie Has Dumb Questions

All--

I have been on the forum for some time and somewhat active on the Stamp side. Thanks to Martin Hebel, HERE I am.

I have very, very fundamental questions regarding the Propeller environment with which I should begin. I am very comfortable with both the BOE and PDB environments. (Who wouldn't be?) There does not seem to be an equivalent environment for the Propeller chip. The closest I can find is the Propeller Education Kit, but I may well be wrong about that, too.

I need all 32 I/O pins for my project. (Well, maybe not ALL of them, but certainly more than the eight accessible pins available with the Propeller Demo Board.) My reading tells me that the Propeller Education Kit will let me breadboard the chip and gain access to all the pins. Does the kit also provide the other functions I--as a newbie--will need, such as a VGA port (I see no mention of it in the summary documentation).

Forgive me if I have wrong impressions . . . that's what being a newbie is all about!

Welcome Bill!
I knew you'd be joining us here :) One of the best getting-started boards is the ProtoBoard. - Access to all 32 I/O with the support hardware, and you can add VGA, all for $25.

But you do need a PropPlug for programming.

If you need to breadboard 1st, you might think about the PropStick USB - a modularized DIP version with support hardware you can plug into your breadboard, and it has the USB on chip.

I'm swamped at work, don't post often currently, but many others will answer any questions you have.

Happy Spinning,
Martin

Martin (and All)--

Ha! I knew I would get you!

My reading tells me that I would have to find out how to build a VGA interface to the breadboarded PropStick USB. I am sure that there is a lot of documentation concerning that interface. Would someone be kind enough to point me in its direction?

Bill,

Welcome!

check out SpinStudio at ucontroller.com

also in the "tutorials" section there is the Propeller cookbook. It will show you how to add many features to your projects.

Some features are difficult to add because the connectors do not fit easily into the standard 0.1" solderless breadboard.

I'm sure other's will respond with some other directions for you to explore as well.

Bill,
I recommend the ed kit because it offers you every pin to use tomorrow. And let's you change your mind in a second. And it includes the prop plug and a nifty box.
Con: the mouse/keyoard/monitor accessory kit doesn't fit without a lot of messing around -- it's easier to just wirewrap those connections and skip the socket kit.
And the breadboard will be always handy for working out new components.

The proto board is not as friendly or flexible -- you'll have to solder your access points. In its favor the mouse/keyboard/monitor assessory kit fits right into the board. But you'll still have to solder it and the accompanying resistors. Plus it is quite inexpensive, especially if you get a five pack....

Just apropos:
The "video interface" consists of three resistors (1 k, 470R, 220R) joint to any plug you like http://forums.parallax.com/images/smilies/smile.gif - and coming off out of 7 possible 3 pin posistions you like... The Prop is flexible...

Be sure and grab a copy of the "Cookbook"
ucontroller.com/Propeller%20Protoboard%20Designs%20for%20the%20Beg inner.pdf (http://ucontroller.com/Propeller%20Protoboard%20Designs%20for%20the%20Beg inner.pdf)

Naturally, I'm a big fan of the Protoboard myself..
Welcome to the group!
