From 63ea7464925b8cbeb8623d08a2bde0b1d2044047 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Thu, 24 Mar 2011 17:27:38 -0400 Subject: Adding /wirish/boards/ for easier porting; shrank PIN_MAPs. /wirish/boards/ contains xxx.h and xxx.cpp (for xxx=maple, maple_native, maple_mini, maple_RET6). The headers contain the board-specific #defines that used to live in boards.h (except BOARD_INIT, which was removed). The CPP files contain the PIN_MAP definitions that used to live in boards.cpp, and a proper boardInit() function to replace the old BOARD_INIT macro. This will make it easier to add new boards in the future. struct PinMapping was renamed struct stm32_pin_info, and was moved into a new wirish_types.h. Its external interrupt field was moved into struct gpio_dev, which saves memory by storing an afio_exti_port per port, rather than one per pin. Also rearranged the stm32_pin_info fields to improve packing. Maple's PIN_MAP is now down to below 500 bytes. --- wirish/boards/maple_native.h | 64 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 wirish/boards/maple_native.h (limited to 'wirish/boards/maple_native.h') diff --git a/wirish/boards/maple_native.h b/wirish/boards/maple_native.h new file mode 100644 index 0000000..21fc480 --- /dev/null +++ b/wirish/boards/maple_native.h @@ -0,0 +1,64 @@ +/****************************************************************************** + * The MIT License + * + * Copyright (c) 2011 LeafLabs, LLC. + * + * Permission is hereby granted, free of charge, to any person + * obtaining a copy of this software and associated documentation + * files (the "Software"), to deal in the Software without + * restriction, including without limitation the rights to use, copy, + * modify, merge, publish, distribute, sublicense, and/or sell copies + * of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be + * included in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, + * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND + * NONINFRINGEMENT.
