Persistent Channels

Functions → Persistent Channels

Persistent channels save their values to non-volatile storage on the display. Values are restored when the device powers on, surviving power loss and config reloads.

Use Cases

  • Store user-adjustable settings (shift point offsets, display preferences)
  • Retain counter values that must survive ignition cycles
  • Hold calibration offsets set by the driver

Configuration

  1. Open Functions → Persistent Channels.
  2. Click Add to add a channel to the persistent list.
  3. Select the Channel to persist.

Both numeric and string channels are supported.

Behaviour

  • On startup, stored values are loaded from the device and written to the configured channels.
  • On power-down (or when a Store event is triggered), current channel values are written to storage.
  • Only channels in the persistent list are saved — other channel values are lost on power cycle.

Note: Only one function should write to a given channel. Do not configure the same channel as both a persistent channel and an active output from another function.
