From 8f251e8a9d46634be4741f7f1aef3d52fb1b7dba Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Fri, 31 Dec 2010 18:18:39 +0100 Subject: Some more file/path restructuring. All #includes now explicitly use the "" format. If you want to get rid of the "libopencm3" prefix in your local project you can add a respective -I entry in your Makefile (not recommended though). All .ld files and .a libs are installed in $(TOOLCHAIN_DIR)/lib directly (as before), but are now renamed to avoid potential conflicts now or in the future. Examples: libopencm3_lpc13xx.a libopencm3_lpc13xx.ld libopencm3_stm32.a libopencm3_stm32.ld --- include/libopencm3/lpc13xx/gpio.h | 100 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 100 insertions(+) create mode 100644 include/libopencm3/lpc13xx/gpio.h (limited to 'include/libopencm3/lpc13xx/gpio.h') diff --git a/include/libopencm3/lpc13xx/gpio.h b/include/libopencm3/lpc13xx/gpio.h new file mode 100644 index 0000000..21f8294 --- /dev/null +++ b/include/libopencm3/lpc13xx/gpio.h @@ -0,0 +1,100 @@ +/* + * This file is part of the libopencm3 project. + * + * Copyright (C) 2010 Uwe Hermann + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 3 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
