硬件概览

它是如何工作的?

EnOcean Click基于EnOcean的双向收发器网关模块TCM310。它通过在一端提供双向无线电接口和另一端提供串行接口来实现EnOcean 868MHz无线电系统的网关,采用ASK调制类型和125Kbps的数据速率。该模块在接收和发送模式下的电流消耗较低,具有-96dBm的接收灵敏度,配备了板载的868MHz芯片天线。它通过将电磁能、太阳

能和热电能转换为电能来生成其电能,从而作为无电池自供电设备工作。TCM310模块可以使用智能应答技术作为多达15个双向传感器的总站。EnOcean模块使用UART接口,默认情况下使用常用的UART RX和TX引脚与主机微控制器进行通信。此外,这个Click board™还具有读取和操作模式,可以通过mikroBUS™插座上的EN引脚来激活。

操作模式默认使用拉下电阻设置。通过RST引脚路由的复位引脚提供了通用的模块复位功能。这个Click board™只能使用 3.3V逻辑电压级别操作。在使用不同逻辑电平的MCU之前,板上必须进行适当的逻辑电压级别转换。此外,它配备了一个包含函数和示例代码的库,可用作进一步开发的参考。

/*!
 * \file 
 * \brief Enocean Click example
 * 
 * # Description
 * This example reads and processes data from EnOcean Clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and sets the driver handler.
 * 
 * ## Application Task  
 * Reads the received data and parses it on the USB UART if the response buffer is ready.
 * 
 * ## Additional Function
 * - enocean_process - The general process of collecting data the module sends.
 * - make_response - Driver handler function which stores data in the response buffer.
 * - log_response - Logs the module response on the USB UART.
 * - log_example - Logs button events on the USB UART.
 * - check_response - Checks if the response is ready and logs button events.
