WiPort 03.04.06
Need to use serial for first WIPORT configuration
Inverting serial, instead of talking to the PIC, talking to the WiPort
Through zterm, hit 0 to connect
Hold down to X key
Gateway IP address : 192.168.1.1
8 bits of the host port netmask
WLAN :
N
Find network name (netobj)? Y
Enable Ad Hoc network ( letting other things to connect as an access point) N
Data rate : set to 6
Power management : radial battery cycle N
Save prefs
Fix the antenna to a certain point that needs to be pointed towards a direction
Try and reload web based interface
192.168.1.102
If one is trying to connect to the wiport, it can only handle one at a time.
Once set up, pic can talk to the WIport using hex invertor
Wiport over Bluetooth. Wiport is easier than Bluetooth. Wiport covers a much larger area. Bluetooth is for personal space areas of about 2ms or so. Less battery power also. Wiport has 300 ft range. Robust connection and range of signal.
MINI ITX boards:
Full blown 17x17 motherboard like the computer. Much more powerful than a PIC. DO need the power to do multimedia.
Mac minis are mini ITXes (nano ITX) can run Pentium, windows
Wireless servers : ITP sandbox
To get access to sandbox, email tom about accessing sandbox.
Then set it up to make it talk to the outside world
With the mini itx, we don’t need one.
MINI ITX
IDE 2.5” 1.8 harddrive, or compact flash (difference like video ipod n nano) power is the issue here- battery usage 1gig CF= 60 bucs
Depends o nthe OS that is used,. Windows xp more than linux.
Have to test it out to see power usage
Mini ITX sites : email and ask Patrick before ordering them
Computer GATE computergate.com
Mini ITX link
800 mhz processor MINI ITX board $100 : EPIA -800
128-258 RAM $20
HD :CF or mini hard drive $20-200 , connector for the Compact Flash
Mini hard drive – adaptor = $10
Power $30 ATX connection power
ATX : Big computer desktop boards
ITX : mini motherboards
Mini ITX: working with the computer, scripting languages are allt here, C C++ java, can run servers on it also, graphical environments as well.
To connect to motors, etc, use serial, usb or connect to an XPORT to talk to eachother. Sensors hooked up into the Xport to talk to the computer to get data in.
Knobs etc. on the XPort
XPort with serial / Ethernet into the mini itx
We have to build our MINI ITXes
For the wiport, need a good fanning/ cooling system- heat sync etc
WIport and Serial RF:
Same range,
Wiport has everything bundled together. No protocol needed, has web access.
RF: buy a transceiver, receiver 2 serial connections going on. Have to do our own protocol.
