I have one simple question regarding LCP1754FBD80. Do it possible to create 2 or 3 virtual serial port and one HID device in one time through USB for this controller?

Hi Michal Wolowik,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
I believe you want to implement a composite USB device, definitely, the LPC LCP1754FBD80 is capable of making it.
Have a great day,

Yes, I want to build composite usb. Can I get some code example or documentation how to do this?

Thanks

Hi Michal Wolowik,

Thanks for your reply.
There's a USB composite device demo which illustrates set up a USB composite device consist of HID and CDC class in the LPC1769's LPCopen library, please down this library via the following link:
