RPM3_ parameters¶

9 parameters in the RPM3_ family. ArduCopter 4.7 only — other vehicles share many of these names but not always the same ranges or meanings.

RPM3_DC_ID¶

DroneCAN Sensor ID

DroneCAN sensor ID to assign to this backend

Range	`-1` to `10`
Increment	`1`
User level	Advanced

RPM3_ESC_INDEX¶

ESC Telemetry Index to write RPM to

ESC Telemetry Index to write RPM to. Use 0 to disable.

Range	`0` to `10`
Increment	`1`
User level	Advanced

RPM3_ESC_MASK¶

Bitmask of ESC telemetry channels to average

Mask of channels which support ESC rpm telemetry. RPM telemetry of the selected channels will be averaged
