LPC1769 USB drivers

[lpcware]

I have searched for quite some time to understand the on-chip USB drivers that the LPC1769 is supposed to have, but I have a hard time finding any real documentation. The available examples (e.g. USB HID) seem quite bloated. I have also understood that the on-chip drivers are quite disliked. So, my questions:

1) Is there any API documentation for the on-chip USB drivers?
2) Does anyone know of a more minimal example to implement e.g. a USB keyboard?
3) What other options are there besides the on-chip drivers?

As far as I can see it has no USB drivers...

Not for the LPC17xx, but the LPC13xx has on-chip USB drivers for HID and MSD implementation. Search for application note AN10904 & AN10905.

I think the above mentioned HID application note will solve most of it (at least I hope so :)

Using a open-source stack or writing your own one :)
