基于STM32F103C8T6的LoRa模块通信,使用ZLG的SX1276方案，SX1276/77/78 收发器主要采用LoRaTM 远程调制解调器，用于超长距离扩频通信，抗干扰性强，能够最大限度降低电流消耗。借助升特的LoRaTM 专利调制技术，SX1276/77/78 采用低成本的晶体和物料即可获得超过-148dBm 的高灵敏度。此外，高灵敏度与+20dBm 功率放大器的集成使这些器件的链路预算达到了行业领先水平，成为远距离传输和对可靠性要求极高的应用的最佳选择。相较传统调制技术，LoRaTM调制技术在抗阻塞和选择性方面也具有明显优势，解决了传统设计方案无法同时兼顾距离、抗干扰和功耗的问题。

功能描述：该程序用于显示心电采集电路采集到的心电信号，通讯采用串口通讯，实时在图表上显示接收到的信号，同时具有数据库功能，可以保存每次接收到的数据，用于回放数据。 开发环境：C++ Builder 6.0 所用控件：AbsoluteDatabase-Functional Description: The program used to display ECG acquisition circuit to the ECG acquisition, communications using serial communication, real-time chart shows the received signal, but also has a database function, can be preserved for each received data, using in the playback data. Development Environment: C++ Builder 6.0 used in the control: AbsoluteDatabase
