<p>搭载无线LAN(Wi-Fi)功能并不是客户开发产品的最终目的,重要的是嵌入式应用程序要实现什么目的、具有怎样的附加值。</p>
<p>将村田制作所模块连接到STM32H743I-EVAL(测试板),并备齐其工作所需要的全套软件。基本上不需要繁杂的校准作业。客户可以专注于开发应用程序,使用必要的功能。</p>
<p>可以根据客户需要的功能,只提供必要的分割部分。可以减少开发工时数,合理且不失时机地开发。</p>
<p><strong>解决方案的特点</strong></p>
<p><strong>可以迅速创建Wi-Fi、Bluetooth开发环境</strong></p>

<p>1. 缩短研发时间<br />
将可以直接实现批量生产的组合作为整体解决方案(Turnkey Solution),提供给客户。可以尽量减少在样机研制中常见的“浪费”、“返工”,研发实现商品化的应用程序。</p>
<p>2. 支持低耗电<br />
通过STM32 Dynamic EfficiencyTM、Wi-Fi及Bluetooth的组合来支持节电功能。</p>
<p>3. 缩短启动时间、提高数据吞吐量<br />
OS启动时间短于Linux,可以高速启动,并使用无线。(参考示例) i.MX6 solo(Linux)约为20 [s] ,STM32H7 RTOS约为488[ms] (从接通电源到传输电波的时间)而且,数据吞吐量的速度提高到STM32F429的微型计算机的约3倍</p>
<p>4. 高API兼容性<br />
Wi-Fi驱动器通过API兼容来支持IEEE802.11 b/g/n/ac 的module。在将来更新Wi-Fi模块时也能轻易应对。</p>
<p>5. 支持符合客户规格的功能(任选)<br />
也能支持TX GLOM(提高传输数据吞吐量)功能和DFS(AP模式)功能。而且,也能根据规格选择Wi-Fi、BT的路径</p>
<p>6. 全方位支持<br />
可以全方位支持客户利用ST Microelectronics公司提供的ST32CubeMX、村田制作所提供的“无线功能评价服务”、“电波法认证/Wi-Fi认证通过支持服务”,实现从产品研发到批量生产/销售。</p>
<p>7. 支持WTS(Wi-Fi认证程序)(任选)<br />
支持数据吞吐量测量工具和802.11AC用Wi-Fi认证程序</p>
