These are the USB libraries used on the keyboard. Small fixes/tweaks have been made.
NXP has been kind enough to provide a pretty good USB library for use with their microcontrollers. There are a few showstopper bugs in the current version that don't seem to be getting fixed, so I've forked the project here so we can maintain a community version that includes the fixes.
The original library is from http://www.lpcware.com/content/project/nxpusblib.
This code is originally created and licensed by NXP - see the License.txt file in this repository.
The additions and modifications in this library are released under the same license, but are not contributed by anyone officially with NXP.
- Fixed USB enumeration when using compiler optimization (added volatile
keywords to some global variables)
- Fixed in nxpUSBlib v0.98
- Add missing macro definition required to compile with GNU GCC for ARM Embedded (DATA(x))
