From 266be307770abe11c220eb493388807920914b7a Mon Sep 17 00:00:00 2001 From: Scott Shawcroft Date: Fri, 25 Aug 2017 13:00:27 -0700 Subject: atmel-samd: Introduce a nvm module for non-volatile byte-level memory access. (#203) * atmel-samd: Introduce a nvm module for non-volatile byte-level memory access. This allows for persisting small configuration values even when the file system is read-only from CircuitPython. Fixes #160 * Review feedback: * Add tests. * Fix non-zero index. * Fix len() --- shared-bindings/nvm/ByteArray.h | 43 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 shared-bindings/nvm/ByteArray.h (limited to 'shared-bindings/nvm/ByteArray.h') diff --git a/shared-bindings/nvm/ByteArray.h b/shared-bindings/nvm/ByteArray.h new file mode 100644 index 000000000..43d942c23 --- /dev/null +++ b/shared-bindings/nvm/ByteArray.h @@ -0,0 +1,43 @@ +/* + * This file is part of the Micro Python project, http://micropython.org/ + * + * The MIT License (MIT) + * + * Copyright (c) 2017 Scott Shawcroft for Adafruit Industries + * + * 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.
