I had made my terminal capable of using TCP/IP protocol what network layer should come above it ? None, as far as I know. Just your application. Your application uses TCP/IP to connect to the website on a specific port. Then it's just a matter of your website and your terminal working with the same data protocol that you design yourself to meet your needs. how to implement that ?
where to get help from about "terminal to call a public website"? The Dallas DS80C411 has built-in TCP/IP capabilities that I know work, and they have lots of libraries to support it. That'd be one way. Other than that, no-one can answer "how to do it." It depends on what processor you use, what Ethernet transceiver you use, etc. But if you have a TCP/IP stack and your hardware is talking via the local Ethernet, it's just a matter of opening connections via that TCP/IP stack. i think solution is Http protocol,i have seen that also but not able to get the solution,if there is any doc or link or code that can help me out please help!! Your question is too vague. You have work to do yourself. We can help you but we cannot answer questions like this. There's just no way for us to help you since we don't know nearly enough about your project to give you design recommendations. It's also doubtful someone has written code to do exactly what you need to do. You're going to have to research TCP/IP, research the microcontroller you use, research how you need to connect the hardware between the two, and come up with your own idea on what kind of high-level protocol you want to use between your terminal and the Internet website. We'll all be happy to ask any questions you have along the way, but you need to understand that only you can make the decisions and you're going to have to understand all the technologies to make it work. We cannot do that for you, we can only help you when you get stuck along the way. The good news is that if you get this working on your own, writing your own code rather than spending time looking for an existing solution to copy, you'll become an expert with the 8051 microcontroller, an expert with TCP/IP (because you'll be familiar with it at a much more complete level than most), and your marketable skills will make you a much more valuable developer. Take advantage of this opportunity to learn all about these technologies and master them! It's much more rewarding spending time doing this yourself than spending time looking for existing designs to copy. Regards, Craig Steiner |
