NXP LPC Virtual Com port library

[MattHollands]

Hi!

I have designed a board that uses the NXP LPC11U24 chip. I want to use the USB port to create a virtual com port so that I can communicate with my PC but I am really struggling with limited documentation.

I have been using LPCXpresso from NXP who provide the LPCOpen libraries for the 11U14 chip which includes the nxp_lpcxpresso_11u14_usbd_lib_cdc example. I can successfully build their example and run to create a vcom port, however when I try to use their code in my own project I cannot get it to work! The device just does not show up on my PC and I can't figure out what is going on. The NXP forums have not been particularly helpful.

I COULD just base my project on their example by just adding the extra code to do everything else - but their example is in C and I really need to be using C++ for this application so I really have to recreate the project. Frankly, the whole USB stack is very complex and I don't really have time to learn everything that is going on right now (coming up to the end of my degree...) - I am basically hoping to find a library/driver etc that will do the heavy lifting for me.

So, does anyone know how I could get this working in LPCXpresso, or if not can anyone recommend a solution that will make virtual com ports much easier. Something like MBED would be good - however even MBED uses the interface chip to do USB communications and I obviously don't have that in my project.

Thanks!

Keil has a better library.
