Overview
The Project
Configuring the Plugin
Conclusion
Grouping together eight buttons in one plugin provides a means of input to an entire port, and grouping eight leds together gives an effective way of reading a ports binary output.
This tutorial will show how to configure and use the button block & led block plugins.
The program is simple but effective for our purposes. The code takes an input form PORT C and outputs to the respective pin on PORT B.

Once the project has been built enter debug mode by clicking the bug icon on the tool bar.

Configure your plugins like this:   |
Run the simulation by pressing the run button on the tool bar or pressing F5. When a button is pressed the corresponding led will light, then go out when released.
Now open the button block configure dialog and check the "2-state button" box. When the simulation is run now the leds will toggle on and off with each press.
The button block and led block plugins are useful tools for debugging projects requiring port wide input and output.
