LPC1768nxpUSBLib v0.98 to communication over USB cable (CDC)

[thiagosiqueira]

Hi,

I have a LPC1768 and I am using nxpUSBLib v0.98 to communicate over USB cable (CDC). LPC (Device) to PC (Host). I have used the example virtualCOM. When I connect my device in my computer and the port COM is Ok. But I can't communicate with the device using pipocom. I my host sends URB_BULK  out, but my device (LPC) doesn't recive this information. Do you know what can be?

Thanks.

Hello,

Which LPC board are you using?

Also, Have you tried to use another VCOM terminal such as Teraterm or Putty? or were you able to capture the USB transactions with an USB sniffer?

Regards,

Isaac

Thanks Isaac. The problem was my interrupt function that wasn't correct. The library and the example works.
