LPC2000 USB FLOW CONTROLVirtual com

Mark Elek

I am using Virtual com example.
It's working fine.
But I need to send a large block of data from host to device.
I can't implement data flow control.
When I stop reading EP, Blockout interrupt stops been generated.

    Thank you Suresh,
    But I think I forgot to set some register in my microcontroler LPC2144.
    If I don't do any flow control, data keeps going from host to device. As the processing is slow, I lost the middle of the package.
    If I stop reading EP when my buffer is full, Bulkout interrupt isn't generated anymore.
    Regards,
    Mark
