MC95_Serialport

说明：  支持9600，19200等常用各种波特率及自定义波特率，可以自动识别串口，能设置校验、数据位和停止位，能以ASCII码或十六进制接收或发送任何数据或字符，可以任意设定自动发送周期,并能将接收数据保存成文本文件，能发送任意大小的文本文件。 硬件连接方面，传统台式PC机支持标准RS232接口，但是带有串口的笔记本很少见，所以需要USB/232转换接口，并且安装相应驱动程序。(Support 9600, 19200 and other commonly used baud rates and custom baud rates, can automatically identify serial ports, can set check, data bits and stop bits, can receive or send any data or characters with ASCII code or hexadecimal, can arbitrarily set the automatic transmission cycle, and can save the received data into text files, can send any data. Text files of meaning size. In terms of hardware connection, traditional desktop PC supports standard RS232 interface, but notebooks with serial port are rare, so USB/232 conversion interface is needed and corresponding driver is installed.)

使用stm32的串口实现fifo队列缓冲读写数据，值得新手学习((Using STM32 serial port to realize FIFO queue buffer read and write data, it is worth learning by novice.))

VC++串口通讯程序 大家可以看看，错误之处欢迎指出，这时本人花不少时间搞出来的啊(VC serial communication process we can see, the mistake welcome, Then I spend a lot of time in the ah)

自制上位机，可以完成发送接收，测试可用。(Homemade PC can complete sending and receiving, and test is available.)

RS232接收程序 无奇偶校验位 并行输出8位数据与data_ready数据准备好信号(RS232 receive procedures without parity 8-bit parallel output data and data ready signal data_ready)

说明：  关于多块板子利用485总线 采用MODBUS协议实现开关量采集与控制采集，串口打印。(On the use of 485 bus and MODBUS protocol to realize switch data acquisition and control acquisition, serial port printing.)

十六进制向十进制转化的程序，可用于串口通讯编程。(Hexadecimal to decimal conversion program can be used for serial communication program.)
