Hi one of the serial port tricks we used on a PC is a usb-serial box like: http://www.keyspan.com/products/homepage-Serial.spml we use the single ones too - for pesky serial-free laptops. The main problem is getting host usb on the gumstix ;-) Kirk At 11:20 24/05/2005, Philip Trickett (List) wrote: >On Mon, 2005-05-23 at 22:00 -0600, Brad Midgley wrote: > > > Did Craig mention eagle sources a while back? > > > >Yeah, Eagle libs for the gumstix parts would be great! > >I know I talked about this before, but would anyone have a need for a >board with 4 extra serial ports, brought out to 2.54mm headers with >level converters? > >Phil > > > >------------------------------------------------------- >This SF.Net email is sponsored by Oracle Space Sweepstakes >Want to be the first software developer in space? >Enter now for the Oracle Space Sweepstakes! >http://ads.osdn.com/?ad_id=7412&alloc_id=16344&op=click >_______________________________________________ >gumstix-users mailing list >gum...@li... >https://lists.sourceforge.net/lists/listinfo/gumstix-users - http://www.ecs.soton.ac.uk/~km |

Phil, >I know I talked about this before, but would anyone have a need for a >board with 4 extra serial ports, brought out to 2.54mm headers with >level converters? That sort of generic board would be exactly what we'd be looking for.=20 For development and maybe even production it'd be invaluable - especially if it could be used alongside some of the other expansion boards. Lots of embedded platforms come with development/evaluation boards with all this sort of thing exposed through various buttons, LEDs and connectors. It'd be great if something like that was available for the Gumstix I think. As well as being a great way to play with different bits of the Gumstix without picking up a soldering iron, it would be useful for very small production runs (albeit where size isn't an issue) or hobbyists without the resources to develop their own addon boards. Let us know if you knock anything like this together! Cheers Dan --=20 Dan Taylor Software Development Engineer, JTL Systems Ltd PhD Student, Reading University, UK http://www.logicalgenetics.com |

Physically the screw connectors used in things like the mote interface: http://www.xbow.com/Products/productsdetails.aspx?sid=77 are very handy... although 2.54mm headers are nice too ;-) and its what we seem to have covered our gumsense board with at the moment.....

Phil, Back in May you mentioned a "...board with 4 extra serial ports, brought out to 2.54mm headers with level converters". If this is a Gumstix expansion board with additional uarts or a uC providing uart functionality, or preferably an Eagle design for such, I'm interested. How can I learn more?

The ways I can see that it is possible to do this are: Using a Quad UART chip, which would mean it would only be usable by a connex style gumstix. Using devices like the MAX3100 SPi UARTS. This would allow the use of the board by all gumstix boards, but I think would require alot more device driver development. Maybe we could do 'stackable' boards with 2 SPI ARTS on each? Personally, I think the first option is the way to go, but I don't like the 'flimsiness' of the connex connector. Would anyone else be interested in working on this as well? All design would be done in Eagle, and maybe low volume runs could be made by gumstix? Phil |
