Hello,

I'm trying to migrate an application from 8bit/serial to 32bits/USB.
I need PWM, EEPROM, I2C, USB (only a Vcom would be enough)
LPC11U24 seems to be what I'm looking for.
I have ported most of the code of my application on this new hardware using LPCXpresso.
I have seen many annoucements about the embedded USB drivers. Great!
But, it seems that the User manual is quite poor concerning this feature :
- No general guidelines on how to use the functions
- Many bugs (copy/paste)
- Some informations on some stuctures completely missing

I have also not seen any code example using this driver, which could help understanding the documentation.
Have I missed something ?
With the current informations I have, it seems quite difficult to develop something based on this driver.
Any advise would be welcome

Thanks
PP

Dear Prt,

Can you take a look at LPC18xx both its CMSIS release and nxpUSBlib port do have demos that use USB on chip driver. It seems like LPC11U2x and LPC18xx USB on chip driver are same.

With best regards,
Tuong Nguyen

From the user manual it looks like the on-chip USB drivers on the LPC11U2x and LPC1850 and even the LPC1347 are the same. Having looked at the coding examples in NXPUSBLiB and in the LPC1850 peripheral library, I'd still like to see an appnote or slightly better documentation on how to use these on-chip drivers. Especially a CDC example.

You are correct, they are all the same. Until we get better documentation for the use of these drivers I suggest you might download and run the latest version of nxpUSBlib. This library supports these drivers by inserting a thin API layer on top of them and you may gleen some good information on how to use them by seeing how nxpUSBlib interfaces to them.

Here is a video that explains this a bit further: http://www.youtube.com/watch?v=ILUAsgiPJLE

Dear nxpUSBlib team staff,

I've been tracking this thread now, 5 months behind... :-)

The link to that video is no longer available.
Is there any alternative that still works ?
