Using the Parallax Serial Terminal

Using the Parallax Serial Terminal

The Parallax Serial Terminal provides a convenient way to exchange data between the Propeller and your PC. It’s most often used for displaying data from the Propeller – for example, the output of a sensor. You can use the Parallax Serial Terminal (PST) to verify that your program is working properly.

Parallax Serial Terminal is included with the Propeller Tool software download, but is a separate program.

To use the PST your Propeller must be plugged into your PC via its USB cable.
This guide assumes you are using version 1.3 or later of the Propeller Tool application. If you are using an earlier version of the Propeller Tool software,  download the latest from here.
