There's many uses for the Linksys WRT54G wireless router since they released the firmware under GPL license. People are writing custom firmwares & the router makes a perfect embedded system box. It has support for 2 serial devices onboard. There's tons of data on this all over the web and even basic firmware packages at www.openwrt.org
I am currently working on an project to turn the router into a wireless Reef Aquarium controller and datalogger. It's a Wireless Recycled Reef Controller (WRRC). Commercial solutions with minimal features that cost upwards of $700+. We are creating a low-cost feature enriched DIY alternative that's open to the entire community.
We are using 1-wire sensors commonly used in weather stations to input data into the WRRC, and I'd like to add X10 support to control lights, pumps, heaters, etc with the aquarium. Project info can be found here: www.bytality.com/wrrc/
The problem is that the serial output on the WRT54G board only has TX and RX outputs but the firecracker uses strobes from the RTS and DTR lines, which we don't have.
We don't have a Linux C programmer unfortunately, so we are not sure how to proceed with this obstacle. Is there any way the code can be written to use the TX/RX lines and then use a special cable from the header to the firecracker unit that crosses those lines back to DTR/RTS pins?
If **ANYONE** can help us out or even give us some advice, please email me at ***@srjava.cjb.net
Thanks in advance.
