From 34f6e0dd33230441b8a91130467b3164e343853e Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Tue, 9 Jun 2009 04:27:53 +0000 Subject: Deleted Host ClassDriver demos -- not yet started, faster to rebase new ClassDriver demos from the newly schedulerless LowLevel host demos rather than re-convert each demo from the previous scheduler-based implementations. Fixes to MassStorageHost demo to improve compatibility with more USB drives. --- Demos/Host/ClassDriver/CDCHost/CDCHost.c | 279 ------------------------------- 1 file changed, 279 deletions(-) delete mode 100644 Demos/Host/ClassDriver/CDCHost/CDCHost.c (limited to 'Demos/Host/ClassDriver/CDCHost/CDCHost.c') diff --git a/Demos/Host/ClassDriver/CDCHost/CDCHost.c b/Demos/Host/ClassDriver/CDCHost/CDCHost.c deleted file mode 100644 index b83473106..000000000 --- a/Demos/Host/ClassDriver/CDCHost/CDCHost.c +++ /dev/null @@ -1,279 +0,0 @@ -/* - LUFA Library - Copyright (C) Dean Camera, 2009. - - dean [at] fourwalledcubicle [dot] com - www.fourwalledcubicle.com -*/ - -/* - Copyright 2009 Dean Camera (dean [at] fourwalledcubicle [dot] com) - - Permission to use, copy, modify, and distribute this software - and its documentation for any purpose and without fee is hereby - granted, provided that the above copyright notice appear in all - copies and that both that the copyright notice and this - permission notice and warranty disclaimer appear in supporting - documentation, and that the name of the author not be used in - advertising or publicity pertaining to distribution of the - software without specific, written prior permission. - - The author disclaim all warranties with regard to this - software, including all implied warranties of merchantability - and fitness.
