Just Launched: You can now import projects and releases from Google Code onto SourceForge
We are excited to release new functionality to enable a 1-click import from Google Code onto the Allura platform on SourceForge. You can import tickets, wikis, source, releases, and more with a few simple steps. Read More
I posed this question to sales@..., but was direct to ask it here.
I would like to control a small project with a netstix computer using some
form of serial interface, but the pre-built in a case netstix computer only
seems to bring out 10/100 ethernet. A simple 3 wire (tx,rx,gnd) connection
to/from an RS-232 interface (either standard or logic level) would be
perfect. Is that interface available inside of the Netstix computer so that
all I need to do is drill a small hole and thread a 3 conductor wire to my
project? The alternative is to build a bare Netstix with a connex, netCF
and console/breakout board. I suggested to Gumstix that a Netstix in a
slightly bigger case with RJ-45 on one end and a DB9 port on the other would
be interesting to some. I have ignored the USB port since it doesn't have a
simple interface protocol solution (i.e. easily PIC-able) as far as I know.
You best bet would be to get this
I just ordered one of these for the same thing your looking to do it has a
few 4 3.3V TTL Serial interfaces - you could solder direct or add headers to
connect to. the only problem is I don't think your going to fit that in the
Netstix case. I'll confirm that in a day or so but it has a power connector
and mini-usb connector (which you can power it via USB if you like). I
think gumstix needs to create some additional cases to allow some of the
stacking. I have one of the netstix computers together, the other one I
have torn apart and I have the tweener hooked up to update the filesystem
with and I also have the robostix. I have the breakboard and wifistix
coming, so of course my one gumstix will never see that Netstix case again.
What I am looking to do is connect the wifistix expansion to the gumstix
with the breakout board so I can execute serial I/O to servo sequencer
(SSC-32 from Lynxmotion) via Wifi - detached robot with computer brain.
