title bar - portapack-mayhem/mayhem-firmware GitHub Wiki

The PortaPack Mayhem title bar consists of a number of icons, some of which trigger actions and some of which are used to indicate the status of certain subsystems. In some older versions, the title bar also contained either the application name or firmware name and version in the form MAYHEM vX.Y.Z where the versioning is consistent with the standard semantic versioning (major.minor.release) format. This was moved to the footer in latest versions.

Actionable icons can be accessed by touch, or by using the directional buttons (H2) or the directional ring (H1) to move the highlight that indicates which icon is selected. If the highlight is on the main menu, using the up button will move it to the title bar.

Infrequently used icons may be hidden using Settings -> User Interface, if desired.
