C8051F340单片机双串口同时工作 中断接收数据 查询发送数据-C8051F340 MCU pairs of serial ports simultaneously send data to interrupt reception data query

串口通信程序，使用COM1串口进行计算机通信的软件-Serial communication program, use the COM1 serial port for computer communications software

西门子PLC步进电机控制+TD200显示示例-Siemens step moter+ TD200 Demo

串行数据标准选用之我见 RS-232、RS-422与RS-485标准及应用 转换器的构成 -Selection of serial data standards, I see the RS-232, RS-422 and RS-485 standards and the application of the composition of converter

的问题.派尔高协议,控制左转右转时,出现问题.其他功能好用.我用DELPHI写的程序,在MOUSEDOWN中, str := chr($FF)+chr($01)+chr($00)+chr($04)+chr($0F)+chr($00)+chr($14) MSComm1.output := str 在CLICK事件中: str := chr($FF)+chr($01)+chr($00)+chr($00)+chr($00)+chr($00)+chr($01) MSComm1.output := str -Problem. Pelco agreement左转右转control when there are problems. Other features easy to use. DELPHI I used to write the procedures in the MouseDown, str: = chr ($ FF)+ Chr ($ 01)+ chr ($ 00)+ chr ($ 04)+ chr ($ 0F)+ chr ($ 00)+ chr ($ 14) MSComm1.output: = str in the CLICK event: str: = chr ($ FF)+ chr ($ 01)+ chr ($ 00)+ chr ($ 00)+ chr ($ 00)+ chr ($ 00)+ chr ($ 01) MSComm1.output: = str

利用MSComm进行pc串口编程。好用-MSComm to pc using serial programming. Easy to use. . . .

NMEA解析，重组 函数源代码！ 能够根据格式符自定义输出，方便扩展-NMEA parsing, restructuring of the function the source code! Be able to customize the output according to format operators to facilitate the expansion of

实现函数发生器产生的波形能够在电脑显示器上显示。函数发生器通过GPIB卡与电脑连接并传输数据，电脑上通过LABVIEW软件环境完成与GPIB卡的数据通信。在LABVIEW环境下完成了对虚拟仪器前面板以及后台程序框图的设计与编程。在LABVIEW开发环境下，实现对GPIB控制时，采用VISA模块驱动的方法进行编程。设计结果在LABVIEW环境下的虚拟示波器能够实现示波器的功能，能够显示函数发生器所产生的任意波形。- achieve the waveform can be displayed on the screen of the computer which send out by the function generator. The function generator connect to computer through a GPIB card and transfer data. Labview can be communicated with GPIB card and save data on computer. The virtual instrument front panel design and background process diagram programming can achieved under Labview software environment. The realization of GPIB control, using VISA module-driven approach to program in Labview. The result of the design is that the virtual oscilloscope is able to complete the Real oscilloscope function in Labview.

提供I2C总线初始化、工作时的启始位、结束位、提供I2C总线的时钟信号，并返回在时钟电平为高期间 SDA信号线上状态。本函数可用于数据发送，也可用于数据接收-provide I2C bus initialization, the Start-end, provide the I2C bus clock signal, the clock and return to the high-level signal line during the SDA state. This function can be used to transmit data, can also be used for data reception
