start USBCDC with no use MicroLib library

vui nguyen

Hi all,

I'm working on LPC1768 chip of NXP semiconductor with USBCDC protocol, I use KEIL to compile source code and know that USBCDC source code of KEIL have used MicroLib library to decrease capacity of source code instead using Standard library.
But recently, I need some functions to using some other targets and MicroLib is no appropriate.
how to configure standard library to using USBCDC?

    Hi Tsuneo Chinzei,

    I have already used this sample code,and I have been disable "use MicroLib" box, it built fine, usb driver got fine,too. But it have not transfer data.
    Because I use one project to transfer data with system and to compare.
    + test1: I checked "use MicroLib" box,data transfering be good.
    + test2: I unchecked "use MicroLib" box,data transfering be not good.The seems,my system have no get data.
    I think have some diffences between this both.
    Did you test it??
