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.
I am using ATMEL 89C5131 as a Virtual COM port client, with this I am able to send send 255 block Characters with out any problems (I didn't tried more than this number).
Have a look demo program in atmel site: "
You may get some idea.
Thanks, Suresh Kumar Kavula
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
