serialDataStream

serialDataStream shows you how to capture continuous data streams from USB devices and serial ports.

Description

SERIALDATASTREAM is a design pattern for a function to receive and process a continuous stream of data from a device connected to a USB or serial port. This function does not execute as written; it includes explanations and examples for all of the steps required to capture data which is transmitted continuously over a USB or serial interface which use a "virtual COM port". It uses some advanced features of the MATLAB serial port functions and has been successfully used for capturing data at rates up to 1.5 MB/sec. Examples for Windows, Mac OS X, and Linux are included. The MATLAB Instrument Control Toolbox is not required.

This code does not execute as it is written; it is a design pattern with explanations and examples in the comments. You can read it and modify it for your needs.

WARNING: This is code is intended for advanced users who need to capture a high-speed, continuous data stream from a USB/serial port. You must have detailed information about the configuration and operation of your serial device. If you do not need high-speed continuous data capture, then you should look at other code which is easier to understand and use.

• Required Products: MATLAB
• MATLAB release: MATLAB 7.8 (R2009a)
