SX Specific TCP/IP I/O

For the IP2k processors, Ubicom has ip modules for Ethernet, Bluetooth, TCP/IP stack and JVM. See http://www.ubicom.com/solutions/index.html for more information...

For the SX48/52 processors, Virtual Peripherals are available:

Software support includes the TCP/IP Stack and Application Layer Software: Protocols integrated into the SX controller include:

1. IP (Internet Protocol) and ICMP (Internet Control Message Protocol)
2. TCP (Transport Control Protocol, supporting two concurrent sockets)
3. UDP (User Datagram Protocol)
4. ARP (Address Resolution Protocol)
5. DHCP (Dynamic Host Control Protocol)
6. HTTP (Hypertext Transfer Protocol)
7. SMTP (Simple Mail Transfer Protocol)

Questions:

• dipanj9@hotmail.com asks:

  My application uses SX52BD for linking to the ethernet. The commands for performing a read of a PIC in the application are given through the web browser and the response appears again on the web browser. I need to send and recieve data directly from within PC on the ethernet bus to the application PIC rather than having to feed command through the browser/ observe the response on the browser. Kindly suggest what should be done to make this possible. Awaiting reply. Thank you.

  James Newton replies: I have two suggestions: Either A) Read the documentation and the sample source code as listed above and ask specific questions based on that or B) hire a professional consultant to do the work for you.
