Hi,
I am a newbie to USB as well as NXP. I have two LPC11U demo boards: LPCXpresso, and Keil MCB11U10. I am trying to get either of them to speak on the USB port and get enumerated. I would be thrilled to get a test application to talk to it.

Keil has a demo program that requires their RTOS. I do not have that, and I prefer to use the NXP example. I found on this site nxpUSBlib v0.98b.

It looks like I need to create a library before I can compile. The readme provides instructions for how to do that in the section Keil uVision 4 IDE.

The problem is, when I try to build the library, it compiles all that it needs, then chokes in the linker with the message error L6002U: Could not open file C:..\..\...\CDL_LPC11Uxx.lib: No such file or directory.

I confirmed that we do, indeed have the directory. As for that file, I thought we were creating that.
Does anybody have any ideas?

Hi,

I've just tried to build AudioInputDevice from nxpUSBlibv0.98b without problem! Please try again:
   - Double click on nxpUSBlib v0.98b\applications\examples\LPCUSBlib\LPCUSBlib_workspace.uvmpw. This opens Keil multi workspace
   - Select the ToolBar Project\Batch Build... this opens Batch Build window
   - Deselect all then select the following projects:
      + BSP\MCB1000
      + CDL\LPC11Uxx
      + LPCUSBlib\LPC11Uxx_Device
      + Your example ex: Example_AudioInputDevice\MCB1000
   - Clock on Build button in Batch Build window to build your example.

With best regards,

Hi Tuong,
I followed your instructions and it worked for me. I am not sure what I did wrong the first time. I suspect I checked off an illegal combination of boxes.

I built the HID application and it runs fine as well. I even added the function to make the LEDs work on the MCB11U10 board.

I do have some new questions:
1. I found the documentation for the xnpUSBLib v0.98 on line. Is there a way to download a PDF document?
2. Is the source for the HIDClient.exe available? Where can I find it?

Thank you

Hi,

1)For the PDF request, I don't see NXP supports it, but I think you'd like to read offline, so we can go other way by rebuilding doxygen:
      - Install Doxygen builder, Doxywizard.
      - Double click on doxywizard.exe, select toolbar File\Open, then browse to nxpUSBlib v0.98b\doc\Doxygen.conf
      - Switch from tab Wizard to tab Run, then click on Run Doxygen. Wait for the console says finished
      - Click on show_HTML_Output button on the left bottom of tab Run, this opens nxpUSBlib document in HTML form on your default web browser.

2) I have no idea on the source of HIDClient.exe, but I think it is not so difficult to make it by Visual C and you can make it yourself!

With best regards,
