断开RXD,TXD连接HC05D蓝牙的RXD/TXD，可是用手机串口助手收不到数据(hhdhh hjhjhj njshjs)

vc_串口通讯，介绍了如何用VC实现串口通信的原理和源程序(vc_ serial communication, describes how to use the VC to achieve the principle and source of serial communication)

用于在线仪表的 modbus,仅供参考，(online instrument for modbus connection, for information purposes only, thank you)

双串口通信,实现单片机串口的接收数据，和想单片机发送数据的功能，希望对大家有所帮助。(Dual serial communication, the realization of MCU serial port data reception, and want MCU data transmission function, hope to help you.)

WL013开发板，串口通信详细例程，含软件流程框图，c源程序、asm源程序等!适合初学者学习！(WL013 development board, serial communication detailed routines, including software flow chart, c source. asm2 source, etc.! for beginners learning!)

STM32F103ZET6由串口UART4接发信号(Signal Receiving and Sending by UART4 Serial Port)

一个用Visual C++编写的串口通信的例程，实现了一些串口属性的设置。(A use of Visual C++, prepared by serial communication routines to achieve a number of serial port property settings.)

通过串口对温湿度检测，实现对温湿度的检测和读取(The temperature and humidity can be detected and read by serial port.)

说明：  基于单片机对湿度的测量 AD转换用串口调试助手显示湿度(The measurement of humidity based on single chip AD converter with serial debugging Assistant displays humidity)
