Detailed Description

The settings class for the Canandcoder.

This class holds settings values that can be used to reconfigure Canandcoder via Canandcoder::SetSettings Additionally, objects of this class can be filled using Canandcoder.GetSettings which can be used to read the encoder's settings.

Canandcoder enc = Canandcoder{0};
 
// Only settings that are explicitly set here will be edited, so other settings 
// such as the status frame period will remain untouched.
CanandcoderSettings stg;
stg.SetPositionFramePeriod(0_ms); // disables position readings
stg.SetVelocityFramePeriod(20_ms); // sets the rate of velocity measurements to every 20 ms
stg.SetInvertDirection(true); // inverts the encoder direction
 
enc.SetSettings(stg);

Objects returned by the blocking Canandcoder::GetSettings() method will always have all setting values populated and the getters will never return std::nullopt.

However, they may return std::nullopt if the object is either manually constructed and the corresponding getter hasn't been called yet (e.g. calling GetStatusFramePeriod before SetStatusFramePeriod on an object you made) or if the object comes from Canandcoder::GetSettingsAsync() and not all settings have been received (use AllSettingsReceived() to check if all are present)

cppreference on std::optional may be helpful here.

Example blocking fetch:

Canandcoder canandcoder{0};
CanandcoderSettings stg = canandcoder.GetSettings();
if (stg.AllSettingsReceived()) { // check for timeout
  fmt::print("status frame period: {}\n", *stg.GetStatusFramePeriod()); // print the status frame period (usually 1000 ms)
}

Member Function Documentation

◆ GetDisableZeroButton()

std::optional< bool > redux::sensors::canandcoder::CanandcoderSettings::GetDisableZeroButton ( )

Gets whether or not the sensor should disallow zeroing and factory resets from the onboard button (0 for allow, 1 for disallow, std::nullopt for unset).

Returns: whether or not the encoder has its onboard zero button's functionality disabled (0 for allow, 1 for disallow, std::nullopt for unset).

◆ GetInvertDirection()

std::optional< bool > redux::sensors::canandcoder::CanandcoderSettings::GetInvertDirection ( )

Gets whether or not the encoder has an inverted direction (0 for no, 1 for yes, std::nullopt for unset).

Returns: whether or not the encoder has an inverted direction (0 for no, 1 for yes, std::nullopt for unset).

◆ GetPositionFramePeriod()

std::optional< units::second_t > redux::sensors::canandcoder::CanandcoderSettings::GetPositionFramePeriod ( )

Gets the position frame period in seconds [0..65.535], or std::nullopt if the value has not been set on this object. A value of 0 means position messages are disabled.

Returns: the position frame period in seconds [0..65.535], or std::nullopt if the value has not been set on this object.

◆ GetStatusFramePeriod()

std::optional< units::second_t > redux::sensors::canandcoder::CanandcoderSettings::GetStatusFramePeriod ( )

Gets the status frame period in seconds [1..65.535], or std::nullopt if the value has not been set on this object. A value of 0 means status messages are disabled.

Returns: the status frame period in seconds [1..65.535], or std::nullopt if the value has not been set on this object.

◆ GetVelocityFilterWidth()

std::optional< units::millisecond_t > redux::sensors::canandcoder::CanandcoderSettings::GetVelocityFilterWidth ( )

Gets the velocity filter width in milliseconds [0.25..63.75], or std::nullopt if the value has not been set on this object.

Returns: the velocity filter width in milliseconds [0.25..63.75], or std::nullopt if the value has not been set on this object.

◆ GetVelocityFramePeriod()

std::optional< units::second_t > redux::sensors::canandcoder::CanandcoderSettings::GetVelocityFramePeriod ( )

Gets the velocity frame period in seconds [0..65.535], or std::nullopt if the value has not been set on this object. A value of 0 means velocity messages are disabled.

Returns: the velocity frame period in seconds [0..65.535], or std::nullopt if the value has not been set on this object.

◆ GetZeroOffset()

std::optional< units::turn_t > redux::sensors::canandcoder::CanandcoderSettings::GetZeroOffset ( )

Gets the zero offset of the encoder.

The zero offset is subtracted from the raw reading of the encoder's magnetic sensor to get the adjusted absolute position as returned by Canandcoder.GetAbsPosition().

Returns: the zero offset [0..1), or std::nullopt if the value has not been set on this object.

◆ SetDisableZeroButton()

void redux::sensors::canandcoder::CanandcoderSettings::SetDisableZeroButton ( bool disable )

Sets whether or not the sensor should disallow zeroing and factory resets from the onboard button. By factory default, the sensor will allow the zero button to function when pressed (disable=false)

Parameters

disable whether to disable the onboard zeroing button's functionality

◆ SetInvertDirection()

void redux::sensors::canandcoder::CanandcoderSettings::SetInvertDirection ( bool invert )

Inverts the direction read from the sensor. By factory default, the sensor will read counterclockwise from its reading face as positive (invert=false).

Parameters

invert whether to invert (negate) readings from the encoder

◆ SetPositionFramePeriod()

void redux::sensors::canandcoder::CanandcoderSettings::SetPositionFramePeriod ( units::second_t period )

Sets the position frame period in seconds. By factory default, position frames are sent every 20 milliseconds (period=0.020_s) If 0 is passed in, position frames will be disabled and the methods Canandcoder::GetPosition() and Canandcoder::GetAbsPosition() will not return new values.

Parameters

period the new period for position frames in seconds in range [0_s, 65.535_s].

◆ SetStatusFramePeriod()

void redux::sensors::canandcoder::CanandcoderSettings::SetStatusFramePeriod ( units::second_t period )

Sets the status frame period in seconds. By factory default, the encoder will broadcast 1 status message per second (period=0.020_s).

Parameters

period the new period for status frames in seconds in range [1_s, 65.535_s].

◆ SettingAddresses()

const std::vector< uint8_t > & redux::sensors::canandcoder::CanandcoderSettings::SettingAddresses ( ) const

overridevirtual

Gets the array of settings addresses this settings class records.

Returns: DetailsKey array

Reimplemented from redux::canand::CanandSettings.

◆ SetVelocityFilterWidth()

void redux::sensors::canandcoder::CanandcoderSettings::SetVelocityFilterWidth ( units::millisecond_t widthMs )

Sets the velocity filter width in milliseconds to sample over. Velocity is computed by averaging all the points in the past widthMs milliseconds. By factory default, the velocity filter averages over the past 25 milliseconds.

Parameters

widthMs the new number of samples to average over. Minimum accepted is 0.25 milliseconds, maximum is 63.75 ms.

◆ SetVelocityFramePeriod()

void redux::sensors::canandcoder::CanandcoderSettings::SetVelocityFramePeriod ( units::second_t period )

Sets the velocity frame period in seconds. By factory default, velocity frames are sent every 20 milliseconds (period=0.020_s) If 0 is passed in, velocity frames will be disabled and Canandcoder::GetVelocity() will not return new values.

Parameters

period the new period for velocity frames in seconds in range [0_s, 65.535_s].

◆ SetZeroOffset()

void redux::sensors::canandcoder::CanandcoderSettings::SetZeroOffset ( units::turn_t offset )

Sets the zero offset of the encoder directly, rather than adjusting the zero offset relative to the currently read position.

The zero offset is subtracted from the raw reading of the encoder's magnetic sensor to get the adjusted absolute position as returned by Canandcoder.GetAbsPosition().

Users are encouraged to use Canandcoder.SetAbsPosition instead.

Parameters

offset the new offset in rotations [0..1)
