From 4c6b056b8467bb6513224527ff3120ef905de397 Mon Sep 17 00:00:00 2001 From: Paul Selkirk Date: Wed, 11 Nov 2015 14:46:28 -0500 Subject: Lots of cleanup. Clean up and simplify(?) Makefile. Add copyrights as needed. Add include guard to stm-fmc.h. Move MX_USART2_UART_Init back to stm-init.c for possible copyright reasons. Move libc, src, and include files to top level. --- stm-uart.h | 49 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 stm-uart.h (limited to 'stm-uart.h') diff --git a/stm-uart.h b/stm-uart.h new file mode 100644 index 0000000..7019a48 --- /dev/null +++ b/stm-uart.h @@ -0,0 +1,49 @@ +/* + * stm-uart.h + * --------- + * Functions and defines to use the UART. + * + * Copyright (c) 2015, NORDUnet A/S All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are + * met: + * - Redistributions of source code must retain the above copyright notice, + * this list of conditions and the following disclaimer. + * + * - Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * + * - Neither the name of the NORDUnet nor the names of its contributors may + * be used to endorse or promote products derived from this software + * without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS + * IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED + * TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A + * PARTICULAR PURPOSE ARE DISCLAIMED.
