some questions about USB2SER

Hi guys,

Referring to this previous thread I started some time back, http://forums.parallax.com/showthread.php?p=545512·, I mentioned that I'm working on this phone project back then. Now I'm·getting started on the USB part.

As far as·I gathered, in order to utilise the USB2SER, I have to have this software interfaced to it, in order to start talking to devices (or to program the USB2SER itself.)·I was wondering if anyone has implemented this on a BS2p development board before? If so, what software did you use? Is there any information that can be provided for me so I could do some readup on it myself?

Thanks,
Gab

    Gabe,

    ·· You only need to install the VCP Driver to have access to it.· It will then appear to your computer as a Serial Port, and you will be able to send, receive and use the DTR line to toggle the other pin on the USB2SER, bringing it low.

    Hi Chris,

    Thanks for the reply. Got some additional queries, I am sorry if I have too many questions but I need to understand.

    As this USB2SER adapter is going to be in the phone device that I'm trying to construct, and if I am going to collect data (such as address book, or contact list or such) from different PCs, does that mean I have to install the VCP drivers to every PC that I am going to plug my phone device to?·The PC is supposed to be connected to the phone device by·the USB port, and not by·the·DB9 serial connector, if possible.

    Can I just 'talk' to the USB2SER using just the Basic Stamp editor? Do I have to·design some additional software on the PC just to make it send data from the PC into the·Stamp for processing? What is this VCP drivers you mentioned, is it the FTDI USB Drivers?

    Thanks again for your time,

    Gabe

    Gabe,

    ·· The VCP Drivers need to be installed on any computer tlaking to the USB side of the USB2SER device.· If you're just using that for programming, and nothing else is plugging into it, then no, you wouldn't need them on each computer.· If, however, the USB2SER is the interface to USB for your project you will need them.· And yes, the FTDI VCP Drivers that we use on our USB to Serial Adapter and USB Development Boards is the same driver.
