5. Design Hardware Diagram
What hardware components are used?
DM9000A: Ethernet controller to connect to the network.
USB: Used to interface with the X10 USB RF Transceiver
SDRAM: Memory for the system
Flash: Non-volatile memory to store the web site files

6. 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)

7. 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”);

8. 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

9. Optional Features
Visual alarm clock that switches an appliance on at certain times
