Design Challenges Web Server X10 USB RF Transceiver Previous application notes available Executing dynamic code X10 USB RF Transceiver Biggest challenge so far Drivers are not publicly available for uC/OS II USB communication wasn’t attempted before (no application notes)

Code Example Pseudocode: How to talk to the X10 appliances through the USB? Commands will be sent as strings to X10 USB Transceiver // Turn on Appliance A1 Write_to_x10(“+A1”); // Turn off Appliance A2 Write_to_x10(“-A2”); // Brighten Lamp J1 Write_to_x10(“bJ1”); // Dim Lamp J2 Write_to_x10(“sJ2”);

Test Plan Web Server X10 USB RF Transceiver Driver Serve a simple web page to test GET requests Turn on leds in response to a POST request Retrieve the status of leds through dynamic code X10 USB RF Transceiver Driver Turn on a single appliance through the driver

Optional Features Visual alarm clock that switches an appliance on at certain times Thermostat control SDCARD support for a bigger website
