RC Input Channel Mapping (RCMAP)¶
This article shows how to set up a non-standard RC input channel mapping using the RCMAP feature.
This feature is available in AC3.2.1 and higher (and equivalent Plane and Rover versions).
By default the RC input channels are:
- Channel 1: Roll input
- Channel 2: Pitch input
- Channel 3: Throttle input
- Channel 4: Yaw input
These can be changed by setting the RCMAP_ROLL, RCMAP_PITCH, RCMAP_THROTTLE and RCMAP_YAW parameters using the Mission Planner‘s Config/Tuning | Full Parameter Tree (or Full Parameter List) as shown below.
After changing any of these parameters the flight controller should be rebooted.
Additional information about the
RCMAP parameters can be found for the respective platforms in:
Copter Parameters, Plane Parameters
and Rover Parameters.
As a real example, if your aileron (steering) is on channel 1 and your elevator (throttle) is on channel 2, then the settings should be:
RCMAP_YAW can be whatever channels you want to
make them as long as they are not channels 1 and 2.
For Rover you should also select the receiver channels that will be used
to control the Waypoint select (LEARN_CH)
and the Mode select (MODE_CH).
As an example, the Gear switch (2-way) is on channel 5 and can be
assigned to the
LEARN_CH while the Flap switch (3-way) is on channel
6 and can be assigned to the
