Proteus and Labview simulate serial port function

    Use proteus and labview to simulate serial port functions. The required software are proteus; keil; labview; Virtual Serial Ports Driver.
     Software function introduction: Virtual Serial Ports Driver can virtualize a pair of logically connected serial ports, assuming they are com3 and com4, then com3 and com4 are logically connected together; proteus, as the simulation software of the microcontroller, communicates with the host computer through the simulated serial port com3; keil is used to write the code of the microcontroller. In the proteus simulation, load the HEX file generated by keil for simulation; labview, as the simulation software of the host computer, communicates with the lower computer through the serial port com4.

    Step 1: Install Virtual Serial Ports Driver. After the installation and cracking are completed, click Add pair to virtualize a pair of simulated serial ports com1 and com2. Click Add pair again to virtualize another pair of serial ports com3 and com4, as shown in the figure: Click Additional pair information, you can see that com3 and com4 are logically connected to each other, as shown in the figure:     Step 2: Install proteus. After the installation and cracking are completed, design the microcontroller circuit, pay attention to the serial port settings, double-click COMPIM, and set the serial port com3 baud rate, etc., as shown in the figure: [page]     Step 3: Install keil. After the installation and cracking are completed, write the program code, compile and generate a HEX file, in the proteus file, double-click the microcontroller, in the corresponding Program File column, point to the path of HEX file, that is, complete the loading of HEX file, as shown in the figure:     Step 4: Install labview, pay attention to install VISA driver, after installation and cracking, write program code, pay attention to the setting of serial port, as shown in the figure:      The design mainly solves the sending and receiving problems of serial port, realizes the acquisition of voltage and temperature through single chip microcomputer, displays on LCD1602 liquid crystal, and sends to computer display through serial port. In the sending and receiving part of serial port, the recognition of voltage and temperature data and the processing of data with decimal point are solved. Data recognition mainly uses the handshake signal sent regularly by the host computer labview, and data processing mainly uses the data processing of strings, arrays and array elements.
