A Quick Introduction to the Erbium (Er) REST Engine
|
||||
===================================================
|
||||
Compile the Example
|
||||
-------------------
|
||||
./run.sh
|
||||
|
||||
sudo avrdude -pm128rfa1 -c arduino -P/dev/ttyUSB0 -b57600 -e -U flash:w:er-example-server.osd-er-lp24.hex:a -U eeprom:w:er-example-server.osd-er-lp24.eep:a
|
||||
OSD-Merkur Board
|
||||
----------------------
|
||||
write the images to the OSD-Merkur Board:
|
||||
|
||||
./flash.sh
|
||||
|
||||
EXAMPLE FILES
|
||||
-------------
|
||||
|
|
@ -40,25 +47,6 @@ With client:
|
|||
4) Wait until red LED toggles on mote 2 (server)
|
||||
5) Choose "Click button on Sky 3" from the context menu of mote 3 (client) and watch serial output
|
||||
|
||||
TMOTES HOWTO
|
||||
------------
|
||||
Server:
|
||||
1) Connect two Tmote Skys (check with $ make TARGET=sky sky-motelist)
|
||||
2) $ make TARGET=sky er-example-server.upload MOTE=2
|
||||
3) $ make TARGET=sky login MOTE=2
|
||||
4) Press reset button, get address, abort with Ctrl+C:
|
||||
Line: "Tentative link-local IPv6 address fe80:0000:0000:0000:____:____:____:____"
|
||||
5) $ cd ../ipv6/rpl-border-router/
|
||||
6) $ make TARGET=sky border-router.upload MOTE=1
|
||||
7) $ make connect-router
|
||||
For a BR tty other than USB0: $ make connect-router-port PORT=X
|
||||
8) Start Copper and discover resources at coap://[aaaa::____:____:____:____]:5683/
|
||||
|
||||
Add a client:
|
||||
1) Change the hard-coded server address in er-example-client.c to aaaa::____:____:____:____
|
||||
2) Connect a third Tmote Sky
|
||||
3) $ make TARGET=sky er-example-client.upload MOTE=3
|
||||
|
||||
DETAILS
|
||||
-------
|
||||
Erbium currently implements draft 08 (name "er-coap-07" stems from last technical draft changes).
