View Full Version : Basic Stamp structure like a Javelin

I was reading over how the Javelin was structured. 32K EEPROM with 32K SRAM. The byte codes copied to SRAM from EEPROM at bootup.

Has any thought been given to coding a BASIC stamp for the Javelin chip hardware? What a great expansion that would be. It should allow more RAM variables, Lots more program and data storage and a major speed increase (not having the serial EEPROM bottleneck

Now I know there is an address size limit but it seems to have been ovecome to do Java so couldn't it be overcome for BASIC?

just curious ...

The Basic Stamp BS2 design was created in 1991. Since then thousands have been sold. It's small, it doesn't take a lot of battery power, it's reliable. It's been ported to the SX chip (BS2sx, and I believe BS2p).

Since it's popular, and since it's still being sold, and since there IS a Javelin (which doesn't sell as well, by the way), Parallax may take the view of why spend more money to develop something which has little added benefit (sales)?

And I believe their current efforts in the SX/B arena, to give people native access to the SX chip using a Basic compiler, may do what you want. I think if they made a Java-like module, to run a PBasic-like code, it would take a dramatic re-engineering of the PBasic run-time. The result might not be something you'd like.

Oh, and they purchased the Java run-time engine they're using now inside the Javelin, which made the large address space available. I'm sure no such off-the-shelf expanded run-time engine exists for PBasic.

Allan,

The BASIC Stamp Revision D was our first BASIC Stamp, and it was released in 1993. The BASIC Stamp 2 was released in 1995. We didn't purchase the Javelin's run-time interpreter engine - it was designed and qualified like all other Parallax products. Just wanted to clarify a couple of points. Let the discussion proceed. . .

Sincerely,

Oops, my bad, I've done it again. Thanks for the correction, Ken, I want the real data to get out there, not my mis-understandings. So, why don't you make a PBasic platform out of the Javelin hardware configuration?

Allan,

Come on over for a visit to Parallax and I'll show you why.
