LED Details
You can set either ON or OFF state for the myRIO LEDs.
The roboRIO contains the RADIO, COMM, and MODE LEDs. Every LED associates with two Boolean controls for displaying various colors. For example, the RADIO LED associates with the RADIO (Green) control and the RADIO (Red) control. The following table shows the configuration options to display a green, red, or orange RADIO LED:
| Green | Red | Orange | Off | |
|---|---|---|---|---|
| RADIO (Green) | TRUE | FALSE | TRUE | FALSE |
| RADIO (Red) | FALSE | TRUE | TRUE | FALSE |
