Board of Education (USB) with Atom 24 Pro

I am using the board of education with USB and·needed a faster PIC and bought an Atom 24 Pro. But I am having problems connecting the device with the Com port. With the Stamp 2 there was no connection problem at all.
Anybody has some experience about this?

2. I believe the answer is to by-pass the serial capacitor that is on the BOE. This can be done by wrapping a wire around it, shorting the two leads together. Make sure you get the right capacitor, though. If you short out the power-supply ripple filter capacitor, things will melt.
·· Unfortunately we cannot guarantee compatibility of our products with other than·the products we make them for.· Perhaps the people over at the Atom Support forums can help you establish communication or confirm if there is an issue with your hardware.

In other words, when you cut corners and mix and match electronics by guess and by golly - no one can really come to your aid.
There are Yahoo Web Sites that you might look at, but the last time I viewed them I saw less than 10 postings per month. So questions really go unanswered.
While I can affirm that Parallax is very good as providing support for any defects in its own products, no company can not afford to hand out free parts or development time to support competators.
Generally, if you are working on a Parallax BOE within the Parallax curriculums and goof, they will generously give you a break and get you back on track. Parallax does value their customers and that is why the forum is here.
So, if you are not up to taking a 'hacker's risk and responsiblity', you should either go with all BasicAtom and seek support from them or stay with all BasicStamp. Obviously, the level of support is part of the price of the product. You may pay a bit more for a BasicStamp, but you really are getting more in the after market than most of the competition.
When switching to the BasicAtom, you also have a big software switch. It is not PBASIC. You may get all the hardware right, but still find yourself going nowhere if they don't support the USB in the same manner.
BY THE WAY, BasicStamp does have faster microprocessors than the BS2. Try the new BS2px.

(Or was that size..)
I considered the Basic Atom and several other clones before I picked the Basic Stamps to work with, and I have never regretted it.
Anyway, there's not many things the BS2 can't do, and if you add a real-time clock and a couple of buffer chips, it can probably do those, too...
(That's number one on my wishlist for the BS3; a built-in real-time clock. )
....Not to mention the SX microcontrollers that parallax has to offer.
You can still program them in pBASIC.

May I second the notion about support...It is well worth the slightly higher cost...I have only positive things to say about the post purchase user support that Parallax has...if only Emac, Dunfield (both very good products, BTW), Gateway, and many other hardware and software manufacturers had the same type of support available, we would be discussing next year's models of bi-ped, neural net powered humanoid automations with cold fusion power sources rather than little wheeled bots and crawlers!
All the best

Cats are the creator's method of demonstrating to mankind that man is not the supreme being.
One of the competitor chips included this feature, but it generally upsets the whole system.
Clocks generally interrupt everything to function properly, so they dominate the microprocessor's timing software.
Parallax has it right, you just add a clock that specializes in being itself. Whenever you need it to call the Microprocessor, it can. Whenever the microprocessor needs to find out the time, it can.
This is a much smoother solution than trying to put it all in one package. It doesn't bother the serial port I/O.
Similar issues arise with RAM and ROM, it is usually easier to determine what the project additonally needs and to add that amount. Trying to have the right balance for every application is nearly impossible.· With the newer I2c and one-wire, you again need the right serial timing.
Floating point math is another area that becomes a distraction. Again, a co-processor seems to allow the system to keep it simple.· Nevertheless, you really become a better, more compact programer if you just figure out how to use binary solutions and occasionally have a look up table.
Small is beautiful.
