Hi,

Is there any reason that nxpUSBlib is not implemented for LPC1343 ?
I got some problem with Keil USB stack on LPC1343 and want to try nxpUSBlib
But this library is ported for most of NXP MCU, except LPC1343 :(

Thanks

Adding support for the LPC1343 is on the list of things to do but is not planned for the foreseeable future. There is a LUFA port onto this part here: https://github.com/kevinmehall/LUFA-LPC13xx that you may want to take a look at.

What problem are you having with the Keil stack on this part?

Hi,

I am using USB CDC example for LPC1343 (on LPCXpresso IDE)
But this sample only can work in Debug mode, it does not work in Release mode.
After I build in Release mode, my PC cannot recognize USB CDC device due to some enumeration error !

Chances are the release mode was never tested. You may want to compare the compiler and linker switches of the two modes to see if there is a glaring issue that might cause this. If you can't find it then a good strategy would be to start with the debug mode and change it (optimization, debug level, etc) to attain a release mode configuration.
