Moved all source to the trunk directory. 2009-02-23 08:08:24 +01:00			`#`
			`# LUFA Library`
Add missing documentation to custom BuiltTest hardware mapping files. Fix up old copyright years on some makefiles. 2012-05-27 16:42:30 +02:00			`# Copyright (C) Dean Camera, 2012.`
Clean up excessive whitespace at the end of each line using the wspurify tool made by Laszlo Monda 2010-10-13 16:05:35 +02:00			`#`
Moved all source to the trunk directory. 2009-02-23 08:08:24 +01:00			`# dean [at] fourwalledcubicle [dot] com`
Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists. 2010-10-28 08:08:58 +02:00			`# www.lufa-lib.org`

Use immediate variable expansion in the second-deepest level makefile scripts to prevent multiple evaluation of the PROJECT_DIRECTORIES variable. 2012-07-15 01:04:37 +02:00			`PROJECT_DIRECTORIES := $(shell ls -d */)`
Use auto-detection of project directories for the demo, project and bootloader makefiles. 2012-06-03 17:04:10 +02:00
Add emergency aborts to the recursive makefiles to prevent system failures due to infinite recursion if something happens while building the project lists. 2012-06-04 17:38:05 +02:00			`# This makefile is potentially infinitely recursive if something really bad`

Fix up makefile .NOTPARALLEL heuristics so that linear building is only enforced if no object folder set and the "all" target is run. Rename library "ConfigDescriptor.c" file to "ConfigDescriptors.c" to ensure that object filenames are unique. 2012-07-10 21:33:39 +02:00			`# Need to special-case building without a per-project object directory`
Add OBJDIR optional build variable to the BULD build system module, to allow the user project to relocate the output object and dependency files to a different directory. 2012-06-10 21:39:40 +02:00			`ifeq ($(OBJDIR),)`

Moved USBtoSerial demo the Projects directory, as it is simply an expanded CDC demo. Added const qualifier to Endpoint/Pipe stream write routines. 2009-10-18 07:35:48 +02:00
