Hi!
Has someone experiences with ARM7 and LabVIEW connecting via USB?
I've programmed the ARM Controller and succeeded to communicate with LabVIEW. But it doesn't works solid and so, if someone know about this, it would be very kind to reply. Even if this ist not really a LabVIEW Forum.
My Problem is, that my viRead with the USBRAW in LV wouldn't communicate with my LPC2368. I can send with viWrite without any Problems, but it seems that the IN-Pipe to the HOST doesn't work fine.
But when I read out the Status, it's always fine. Even in front of the viRead, which doesn't want to receive. But it's fine. Indeed!! Fore sure it is. *grr*
So I read out the data with the 'USB-Interrupt-Event', and this works. Nearly. Not every single time, and not if I replug the USB-Connector. But I can receive, sometimes.

Right now I'm not really sure about, how fast it has to be. It depends on what we wanna send and how often we'll detect the A/D Converter. Jan Axelson (USB-Book) wrote, that when the Bulk-Transfer is the only data to transfer it could be also very fast and could also reach the maximum speed.
So I believe that it can reach nearly the Maximum Speed of 1.1 for Bulk-Transfers when we we'll also use circular Buffer. Certainly is, that we'll only send with this connection & nothing else more.
Even the 200KB/s seems to be sufficient at this time.
