Serial Line Follower Kit (#45203)

Ed Stennie

I purchased this kit at one of your EBAY sales and was surprised to learn that I need a sx-key in order to program it before it could be used.· Is this true or is a basic program that is able to report sensor status to the Basic Stamp control board already loaded on the SX28?

Jon Williams

The idea behind that kit was to give you a start and let you modify the code for advanced use, so yes, you need an SX-Key to program it.

Thanks for your reply Jon.· I'm home schooling my daughter and not ready to make the investment in a SX basic tool kit.· Is there any way that I can return the chip to Parallax to get the SLF control program put on the chip?

Jonathan

Ed,

If Parallax can't program it for you (and I don't blame them if they can't), I'd be happy to program it for you. Contact me off list if you need to.

If you want to do that for Ed, that would be great.· I've attached the original SRC file, as well as the updated SX/B file (requires version 1.42) in case you'd like to do that.· Note that I updated the code, but won't be able to test it for a couple days.

Edit: I looked at the [noparse][[/noparse]SX/B] program again and found more areas for improvement - new SX/B attached.

Jon, Ed,

No problem. Dl'd the code, so Ed, let me know if I can help.

Thanks Johnathan for your kind offer but Parallax has offered to help.· I think their response shows why they are second to none in the educational product industry.

anyone have any documentation on the Older 2004 version serial line follower #45203.
I have the board but no documents. I put it away in a box with other SX stuff from 2004.
Now that I'm retired, I have time to play with it.
I Did find reference above to code src.
Would like schematic or description of how it works before I dig into the code to figure it out.
will probably interface to it from another computer.
Anyone have saved all the old documentation?

I will scan my computers to try and find docs.

Is it the QTI Sensor from 2004?

This may be the sensor.
