SNAPconnect Example - McastCounter GUI in wxPython

This example application provides a wxPython GUI that participates in the McastCounter multi-node demonstration via SNAPconnect.

Background

The McastCounter SNAPpy script is pre-installed on SNAP modules delivered with the EK2500, EK2100, and DK-200 evaluation kits. It provides a distributed button-click counter across multiple nodes.

Running This Example

This example uses the wxPython GUI library from www.wxpython.org. Install this library if you don't already have it, for example:

pip install wxpython

This example was most recently tested against wxPython version 3.0.1.1. Other wxPython versions (both older and newer) may also work.

Edit the BRIDGE_NODE tuple near the top of McastCounter.py to provide the serial interface "type" and "port" of your bridge node.

Once you have edited McastCounter.py for your available hardware, simply run:

python McastCounter.py

A small wxPython dialog box should appear, containing a button labeled "Increment" as well as a "Count:" field. "setButtonCount()" calls from other SNAP nodes should update the "Count:" field, and you can also trigger setButtonCount() calls from the SNAPconnect application by clicking on the "Increment" button.

For more details, refer to source file McastCounter.py.

Refer to the 'McastCounter.py' SNAPpy script for more information about the McastCounter demo.
