USBs, COM ports ...

How do I get my program to receive a binary file from a external device, analyze (compare) that binary and react to it. Can I get some help (in VB) about the code that I should use. I'd prefer COM ports but USBs would work. I know how the comparing should look like but I don't know how to store that data and get it! Any help

    Yes. That company is dedicated to showing you what is possible. It is a learning approach, they are not showing you what is practical. Their goal is to give you an idea of how it could possibly work. That's cool and important. I think you got inspired by it. And that was the goal. Now you got the next step and realized that it wasn't the transmitter that was important, it was the decoder that was important. The protocol. The logic behind what is being sent. How to interpret it when you write your own software. In the big scheme of it all, that was exactly what they wanted to accomplish. Now you need to move on and read about protocols and RFC's and standards...

    If you're thinking about wireless data transfer without following one of the WiFi standards, you're in the wrong forum. Umm, no, wrong planet...

    You may find a small program for serial COM port communication including source code and documentation in the knowledgebase on our homepage. The address is:

    http://www.innovatic.dk/knowledg/SerialCOM/SerialCOM.htm

    With this program you can send and receive ASCII and Hex, so you should be able to get "hole through" your radio link. It probably has a very simple protocol or is it you, who should define the protocol

    Good luck

    Well, I wasn't really thinking about TCP/IP. I was thinking about wireless data transfer (not WiFi). Just a personal thing but it is simple radio data transfer from computer to computer. And any information about TCP/IP will be good. Thanks

    You better start by deciding what kind of connection you'll make to the external device. From there, we can give you some help.

    PS: don't forget about TCP/IP if that's an option...

    HUmmm... , I need help about the code for the COM port !!!

    You see, it isn't a company. It is a home thing...
    I mean it is for home use only and is made by the user. No company and stuff. If you looked at the site you could see that there are chapters. At the last one computers, there is a thing called computer controlled transmitter. It is used for morse code (in data form) but I dont want to send morse code but data, like a picture :)
    Any help please !!!

    Thanks gregu33701. I guess u understood what I needed. :)

    Look, it is a homemade device. It works on 1MHz. I'm not trying something big as WiFi. If you want the plans for this go to scitoys.com . I Just asked about any help about writing the code for the program that would drive the radio transmitter and receiver. Any help
    If not then thanks a lot

    I apologize. That looks like an incredibly fun web site. However, you probably need to send an email to the company and ask them about their protocols. As in they way they talk. It is not likely to be anything standard like TCP/IP...
