However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability. END OF TERMS AND CONDITIONS APPENDIX: How to apply the Apache License to your work.

The Rhombus OS is/was distributed under the ISC license. The ISC licsense is a permissive license that allows people do anything with your code with proper attribution and without warranty. The ISC license is functionally equivalent to the BSD 2-Clause and MIT licenses, removing some language that is no longer necessary.

All rights reserved. Copyright (C) 2006-2007 H. Peter Anvin. dtoa() ====== If you enable floating point conversions with CONFIG_LIBC_FLOATINGPOINT, then some files with an unmodified BSD license will be included. That license is similar to the above (modified) BSD license, but has an additional requirement that I state the following: "This product includes software developed by the University of California, Berkeley and its contributors." libc/string/lib_vikmemcpy.c =========================== If you enable CONFIG_MEMCPY_VIK, then you will build with the optimized version of memcpy from Daniel Vik. Licensing information for that version of memcpy() follows: Copyright (C) 1999-2010 Daniel Vik This software is provided 'as-is', without any express or implied warranty. In no event will the authors be held liable for any damages arising from the use of this software.

Altered source versions must be plainly marked as such, and must not be misrepresented as being the original software. 3. This notice may not be removed or altered from any source distribution. libs/libc/math ============== If you enable CONFIG_LIB, you will build the math library at libc/math. This library was taken from the math library developed for the Rhombus OS by Nick Johnson (https://github.com/nickbjohnson4224/rhombus). This port was contributed by Darcy Gong.

Those both have GPL licenses. I am not sure if it is proper or not to lift the content of those tables and still retain this BSD license. I am guessing so, but I am not a copyright attorney so you should use this driver in products at your own risk. include/nuttx/lcd/ili9488.h =========================== Copyright (c) 2011, Atmel Corporation All rights reserved.
