Hi,
I have a device that I originally designed to work on the mscomm1 interrupt.
I have now redesigned it to work on USB (not a lot of redesign, I use the same protocol as in serial).
The serial protocol has some autonomus transmits to the CPU.
I the USB version I send a request for data and then get multiple packets.
As a result I need an interrupt when there is an IN transaction on USB.
I tried making a short timeout on read and having that code embedded in a 1mS timer.
That does not work well. I really need to get an interrupt when ever there is an IN packet from the USB device.
Any ideas?
Thanks,
Martin Green
