RS232 serial data to Multisim

[Muhammamd Azam khan]

Well i want to input data from RS232 which is changed externally by an ADC using Atmel 8051 microcontroller and want this data to be presented in Multisim to perform some analog data signal processing...

I am able to get data from Labview

And have installed the Labview Multisim connectivity toolkit, along with examples... but the examples show the data geneated from Multisim and then presented to Labview

I want the opposite..

Data from RS232 -> Multisim -> Labview..

Hello,

Here are two suggestions:

• Acquire RS232 data in LabVIEW.
• Save the data into a LabVIEW Measurement file (*.lvm).
• In Multisim use the LVM_VOLTAGE source to open the *.lvm file.
• This is a design method called the Virtual Prototype.

The second suggestion is the use of a LabVIEW Instrument for Multisim. The basic idea here is to create an instrument that inputs signals (for example: from the serial port) to a Multisim schematic. Have in mind that continuous updates will not happen in real-time due to the nature of the SPICE simulation.

Here is a good tutorial on how to create these instruments:

I hope this helps.
