Fields

std::vector<uint16_t> AIN_16bits

Readings from 8-bit analog input (ADCs) channels (vector length=channel count) in ADC units.

std::vector<uint32_t> AIN_32bits

Readings from 16-bit analog input (ADCs) channels (vector length=channel count) in ADC units.

std::vector<float> AIN_float

Readings from 32-bit analog input (ADCs) channels (vector length=channel count) in ADC units.

std::vector<double> AIN_double

Readings from analog input (ADCs) channels (vector length=channel count) in Volts.

uint16_t AIN_channel_count {0}

Readings from analog input (ADCs) channels (vector length=channel count) in Volts.

How many different ADC channels are present in the AIN_* vectors.

bool AIN_interleaved {true}

Whether the channels are interleaved (A0 A1 A2 A0 A1 A2…) or not (A0 A0 A0 A1 A1 A1 A2 A2 A2…) in the AIN_* vectors.

std::vector<uint16_t> AOUT_16bits

Present output values for 8-bit analog output (DACs) channels (vector length=channel count) in DAC units.

std::vector<float> AOUT_float

Present output values for 16-bit analog output (DACs) channels (vector length=channel count) in DAC units.

std::vector<double> AOUT_double

Present output values for 16-bit analog output (DACs) channels (vector length=channel count) in volts.

std::vector<uint8_t> DIN

Present output values for 16-bit analog output (DACs) channels (vector length=channel count) in volts.

std::vector<uint8_t> DOUT

Readings from digital inputs; each byte stores 8 digital inputs, or 8-bit port.

std::vector<uint32_t> CNTRIN_32bits

Present digital output values; each byte stores 8 digital inputs, or 8-bit port.

std::vector<double> CNTRIN_double

Readings from ticks counters, such as quadrature encoders.

(vector length=channel count) in ticks.

double sample_rate {0}

Readings from ticks counters, such as quadrature encoders.

(vector length=channel count) in radians, degrees or any other unit (depends on the source driver). The sampling rate, in samples per second per channel

Methods

virtual void getSensorPose(mrpt::poses::CPose3D&) const

Not used in this class.

virtual void setSensorPose(const mrpt::poses::CPose3D&)

Not used in this class.

virtual void getDescriptionAsText(std::ostream& o) const

Build a detailed, multi-line textual description of the observation contents and dump it to the output stream.

If overried by derived classes, call base CObservation::getDescriptionAsText() first to show common information.
