RcParameterMap (UORB message)

TOPICS: rc_parametermap

Fields

Name	Type	Unit [Frame]	Range/Enum	Description
timestamp	uint64			time since system start (microseconds)
valid	bool[3]			true for RC-Param channels which are mapped to a param
param_index	int32[3]			corresponding param index, this field is ignored if set to -1, in this case param_id will be used
param_id	char[51]			MAP_NCHAN * (ID_LEN + 1) chars, corresponding param id, null terminated
scale	float32[3]			scale to map the RC input [-1, 1] to a parameter value
value0	float32[3]			initial value around which the parameter value is changed
value_min	float32[3]			minimal parameter value
value_max	float32[3]			minimal parameter value

Constants

Name	Type	Value	Description
RC_PARAM_MAP_NCHAN	uint8	3	This limit is also hardcoded in the enum RC_CHANNELS_FUNCTION in rc_channels.h
PARAM_ID_LEN	uint8	16	corresponds to MAVLINK_MSG_PARAM_VALUE_FIELD_PARAM_ID_LEN
