Hi Sandeep,
I am currently developing an 802.15.4 based product for use with the
TS-7260/7250. You will probably need to run kernel v2.6 if you plan to
use the Linux box as a hub or a full function device as some level of
"real-time" response is required. I followed the thread on kernel 2.6
development, saw that it was pretty detailed (BTW, my vote is for v2.6
support from TS), and, having a demonstration deadline, decided to
take the cowards path :+). I used a translation micro to act as a
go-between and send ascii commands through the regular serial port. It
let me focus on developing the web controls and not kernel
development. CGI was a bit challenging until I figured out some of its
requirements. The serial port access needed a little program to let
non-root users send data in/out.
Instead of the chipcon 2420, you might choose the 2430 which is the
full micro with rf and serial port. This moves the development from
Linux to an embedded micro with a more deterministic response time. I
am using the Freescale GT16 and the MC13192 rf transceiver with the
"free" Metrowerks compiler. It is free up to 16kbytes of flash.
What I have today is a serial based 802.15.4 interface board to talk
wireless. A similar device to function as a RFD (reduced function
device) that can accept control commands and send status packets.
Control is sent from the TS-7260 with the keypad activating different
nodes and the LCD displaying message response text. A monitor to log
activity. And a web page to activate units through the ethernet (via a
script). Background tasks monitor the keypad and a modified LCD
program updates the screen.
If you do get the SPI stuff running, or want to collaborate a little
more, please let me know. As it is a bit off topic, you can email me
directly at We can post results if others are
interested.
