Hi everyone,

I've tried the LPCOPEN in the Embedded Artists' LPC1788 Developer's Kit example the PC does not recognize the device ...
The example runs ok and I can debug the program step by step in the EA1788 board.
I can't find the causes...

TheLPCXpresso can't finde the implementation of the functions:

Serial_Send((uint8_t *) out_buff, 1, BLOCKING);

and

recv_count = Serial_Revc(in_buff, CDC_TXRX_EPSIZE, NONE_BLOCKING);

Is this usable with EA1788 Board???

It seems to be that nxp didn't make the library for the lpc1788 with lpcopen, is another library that I can use out there?

Thanks, I'll really appreciate your help or advice !

I

The PC needs an "inf" file to load drivers for the USB device. I know, CDC is a standard Windows driver, but you need the "inf". Doesn't work like HID or MSD.
I do not believe a file is provided

here is a template to give you a start, or google "usb CDC inf file"

Thanks, I could solve the problem, and it worked ... only once. I installed the .inf file given by nxp in the LPCOPEN example (applications\LPCUSBlib\lpcusblib_VirtualSerialDevice)

Now it doesn't recognize the hardware when i plug it in...

I've tried a lot of things trying to install the LPCUSBlib VirtualSerial.inf again but without success.
