Does anyone know of an open-source USB “stack” for the LPC214x series?
Is the USB controller in the LPC2148 perhaps similar to a controller in other hardware (for which a driver or stack already exists)?
I know Keil and IAR have some USB examples, but I think they are not open-source.
Have you looked at the links on [the Philips web site? it looks like there are some USB stacks with source available, dunno whether they’re actually open source or not.](http://www.standardics.philips.com/support/techdocs/microcontrollers/all/?scope=LPC2148)
The Philips web site links to the Keil and IAR examples I was referring to.
Basically I’m just looking for USB sources that I can use for a hobby project, modify/enhance/extend and republish on my website without getting into legal trouble.
For the Keil and IAR sources it is unclear if this is the case.
