Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names

温馨提示
在当今的嵌入式系统设计中,使用微控制器(MCU)来控制各种外设已成为标准做法。STM32F103C8T6是意法半导体(STMicroelectronics)出品的一款高性能、低成本的ARM Cortex-M3内核微控制器,广泛应用于工业自动化、消费电子以及物联网(IoT)等领域。其丰富的外设接口和灵活的配置选项使得它成为许多开发者的首选平台。 本项目旨在探讨如何利用STM32CubeMX工具配置STM32F103C8T6微控制器,并通过脉冲宽度调制(PWM)与直接存储器访问(DMA)技术来驱动一种特殊的RGB LED灯带——WS2812B。WS2812B是一种集成了控制电路的高亮度RGB LED,可以实现单线数字控制,非常适合于制作多彩绚丽的灯光效果。 本文档将详细介绍整个项目的开发流程,包括硬件连接、软件配置以及代码编写等关键步骤。我们将从选择合适的GPIO引脚开始,通过STM32CubeMX配置生成初始代码,然后深入探讨如何设置PWM输出以产生正确的信号波形,并且利用DMA技术提高数据传输效率,从而确保每个LED能够准确地按照预期显示颜色。此外,我们还将讨论一些调试技巧和可能遇
