  size_t (*get_channels_number)(void *instance);                            \
  /* Reads the sensor raw data.*/                                           \
  msg_t (*read_raw)(void *instance, int32_t axes[]);                        \

_base_sensor_methods

#define _base_sensor_methods

Value:

  _base_object_methods                                                      \
  _base_sensor_methods_alone

BaseSensor specific methods with inherited ones.

Definition at line 58 of file ex_sensors.h.

_base_sensor_data

#define _base_sensor_data

BaseSensor specific data.

Note

It is empty because BaseSensor is only an interface without implementation.

Definition at line 74 of file ex_sensors.h.

sensorGetChannelNumber

#define sensorGetChannelNumber

(

ip

)

Value:

(ip)->vmt->get_channels_number(ip)

Sensors get channels number.

Parameters

[in]

ip

pointer to a BaseSensor or derived class.

Returns

The number of channels of the BaseSensor

Function Class:

Normal API, this function can be invoked by regular system threads but not from within a lock zone.

Definition at line 106 of file ex_sensors.h.

sensorReadRaw

#define sensorReadRaw	(		ip,
			dp )

Value:

(ip)->vmt->read_raw(ip, dp)

Sensors read raw data.

Parameters

[in]	ip	pointer to a BaseSensor or derived class.
[in]	dp	pointer to a data array.

Returns

The operation status.

Return values

MSG_OK	if the function succeeded.
MSG_RESET	if one or more errors occurred.

Function Class:

Normal API, this function can be invoked by regular system threads but not from within a lock zone.

Definition at line 120 of file ex_sensors.h.

sensorReadCooked

#define sensorReadCooked	(		ip,
			dp )

Value:

(ip)->vmt->read_cooked(ip, dp)

Sensors read cooked data.

Parameters

[in]	ip	pointer to a BaseSensor or derived class.
[in]	dp	pointer to a data array.

Returns

The operation status.

Return values

MSG_OK	if the function succeeded.
MSG_RESET	if one or more errors occurred.

Function Class:

Normal API, this function can be invoked by regular system threads but not from within a lock zone.
