硬件概览

它是如何工作的？

NeoMesh Click - 915MHz 基于 NeoCortec 的 NC1000C-9，这是一款无线 Mesh 网络模块。除了可以由主机 MCU 控制外，NeoMesh Click 还可以用作独立设备。您可以通过系统 API（SAPI）配置模块，这是一种基于 UART 的接口，具有硬件流控制。该接口配置为确保与 FTDI 串行到 USB 电缆直接兼容。使用 NeoMesh Click 作为独立板时，可以通过位于模块侧面的引脚头轻松访问 NeoMesh 模块的应用接口。这个引脚头有八个引脚，标记为 P2-7 的引脚头有六个引脚，允许您使用多达 6 个 12 位 ADC 通道、GPIO、I2C 传感器和 UART 应用 API。此引脚头的特定引脚可用于通过 UART 与外部微控制器接口。该模块还可以通过无线方式进行配置。底部有一个未连接的 WES 跳线。您可以通过连接它来使用无

线加密设置，但前提是它已经通过 WES 程序进行配置。每个 WES 通道都有一个指定的 AES 128 加密密钥。旁边是另一个跳线，VCC，这个跳线已连接。NeoMesh 经过优化，可实现超低功耗操作，允许在小型电池上运行数年。如果您想制作一个超低功耗节点，考虑使用 NeoMesh Click 与一些具有电池管理的低功耗开发板（如 Clicker 2 系列或类似的开发板）一起使用。此场景非常适合节点可以不频繁发送数据且有效载荷较小的情况。NeoMesh 是一个设计灵活的无线系统，允许用户在许多不同的应用领域中构建产品。该系统可以处理数据传输、失去的邻居节点、移动节点等。数据通过网络按顺序从节点传输到节点，直到数据到达目的地。有三种类型的 NeoMesh 设备：协调器、路由器和终端设备。您可以根据需要配

置您的设备。NeoMesh 使用标准 UART 串行接口与主机 MCU 通信，常用的 UART RX 和 TX 引脚，传输速度为 115200bps。硬件控制流通过 CTS 引脚提供。您还可以使用 I2C 接口作为虚拟 UART。I2C 线上有未填充的上拉电阻。可以通过 I2C SEL 跳线启用 I2C 接口。禁用时，您可以使用 WUP 引脚指示模块的唤醒活动状态；否则，WUP 功能不可用。模块可以通过 RST 引脚重置。通用应用活动通过 APP 引脚指示，激活时为逻辑低电平状态。如果无线加密设置 JP2 跳线闭合，您可以通过 WES 引脚启用 WES 客户端。此 Click board™ 只能在 3.3V 逻辑电压级别下运行。使用不同逻辑电平的 MCU 之前，必须进行适当的逻辑电平转换。另外，它配有包含功能和示例代码的库，可作为进一步开发的参考。

 * @file main.c
 * @brief NeoMesh 915MHz Click Example.
 *
 * # Description
 * This example demonstrates the use of NeoMesh 915MHz Click board by showing
 * the communication between the two Click boards.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and configures the Click board for the selected
 * application mode.
 *
 * ## Application Task
 * One Click board should be set to originator mode and the others to receiver 1 or 2.
 * If the SINGLE_RECEIVER_MODE is enabled, the originator device sends a desired message
 * to RECEIVER_1 node and waits for an acknowledge response, otherwise it sends the same
 * message to both RECEIVER_1 and RECEIVER_2 nodes. The receiver devices reads and parses
 * all incoming AAPI frames and displays them on the USB UART.
