Detailed Description

Represents an I2C connection to a Motoron Motor Controller.

Definition at line 1890 of file Motoron.h.

Constructor & Destructor Documentation

◆ MotoronI2C()

MotoronI2C::MotoronI2C ( uint8_t address = 16 )

inline

Creates a new MotoronI2C object to communicate with the Motoron over I2C.

The address parameter specifies the 7-bit I2C address to use, and it must match the address that the Motoron is configured to use.

Definition at line 1897 of file Motoron.h.

Member Function Documentation

◆ calculateCrc()

static uint8_t MotoronBase::calculateCrc	(	uint8_t	length,
		const uint8_t *	buffer,
		uint8_t	init = `0`
	)

inlinestaticinherited

This static method calculates the 7-bit CRC needed for a Motoron command or response. Most users will not need to use this, since most methods in this library automatically append a CRC byte or check received CRC bytes when appropriate.

Definition at line 1781 of file Motoron.h.

◆ calculateCurrentLimit()

static uint16_t MotoronBase::calculateCurrentLimit	(	uint32_t	milliamps,
		MotoronCurrentSenseType	type,
		uint16_t	referenceMv,
		uint16_t	offset
	)

inlinestaticinherited

Calculates a current limit value that can be passed to the Motoron using setCurrentLimit().

Parameters

milliamps	The desired current limit, in units of mA.
type	Specifies what type of Motoron you are using.
referenceMv	The reference voltage (IOREF), in millivolts. For example, use 3300 for a 3.3 V system or 5000 for a 5 V system.
offset	The offset of the raw current sense signal for the Motoron channel. This is the same measurement that you would put into the Motoron's "Current sense offset" variable using setCurrentSenseOffset(), so see the documentation of that function for more info. The offset is typically 10 for 5 V systems and 15 for 3.3 V systems, (50*1024/referenceMv) but it can vary widely.

Definition at line 1815 of file Motoron.h.

◆ clearLatchedStatusFlags()

void MotoronBase::clearLatchedStatusFlags ( uint16_t flags )

inlineinherited

Clears the specified flags in getStatusFlags().

For each bit in the flags argument that is 1, this command clears the corresponding bit in the "Status flags" variable, setting it to 0.

For more information, see the "Clear latched status flags" command in the Motoron user's guide.

See also: getStatusFlags(), setLatchedStatusFlags()

Definition at line 1394 of file Motoron.h.

◆ clearMotorFault()

void MotoronBase::clearMotorFault ( uint8_t flags = 0 )

inlineinherited

Sends a "Clear motor fault" command to the Motoron.

If any of the Motoron's motors chips are currently experiencing a fault (error), or bit 0 of the flags argument is 1, this command makes the Motoron attempt to recover from the faults.

For more information, see the "Clear motor fault" command in the Motoron user's guide.

See also: clearMotorFaultUnconditional(), getMotorFaultingFlag()

Definition at line 1369 of file Motoron.h.

◆ clearMotorFaultUnconditional()

void MotoronBase::clearMotorFaultUnconditional ( )

inlineinherited

Sends a "Clear motor fault" command to the Motoron with the "unconditional" flag set, so the Motoron will attempt to recover from any motor faults even if no fault is currently occurring.

This is a more robust version of clearMotorFault().

Definition at line 1380 of file Motoron.h.

◆ clearResetFlag()

void MotoronBase::clearResetFlag ( )

inlineinherited

Clears the Motoron's reset flag.

The reset flag is a latched status flag in getStatusFlags() that is particularly important to clear: it gets set to 1 after the Motoron powers on or experiences a reset, and it is considered to be an error by default, so it prevents the motors from running. Therefore, it is necessary to call this function (or clearLatchedStatusFlags()) to clear the Reset flag before you can get the motors running. We recommend that immediately after you clear the reset flag. you should configure the Motoron's motor settings and error response settings. That way, if the Motoron experiences an unexpected reset while your system is running, it will stop running its motors and it will not start them again until all the important settings have been configured.

See also: clearLatchedStatusFlags()

Definition at line 1419 of file Motoron.h.

◆ clearUARTFaults()

void MotoronBase::clearUARTFaults ( uint8_t flags )

inlineinherited

Sends a "Set variable" command that clears the specified flags in getUARTFaults().

For each bit in the flags argument that is 1, this command clears the corresponding bit in the "UART faults" variable, setting it to 0.

For more information, see the "UART faults" variable in the Motoron user's guide.

Definition at line 1120 of file Motoron.h.

◆ coastNow()

void MotoronBase::coastNow ( )

inlineinherited

Sends a "Coast now" command to the Motoron, causing all of the motors to immediately start coasting.

For more information, see the "Coast now" command in the Motoron user's guide.

Definition at line 1353 of file Motoron.h.

◆ currentSenseUnitsMilliamps()

static constexpr uint16_t MotoronBase::currentSenseUnitsMilliamps	(	MotoronCurrentSenseType	type,
		uint16_t	referenceMv
	)

inlinestaticconstexprinherited

Calculates the units for the Motoron's current sense reading returned by getCurrentSenseProcessed(), in milliamps.

To convert a reading from getCurrentSenseProcessed() to milliamps multiply it by the value returned from this function using 32-bit multiplication. For example:

uint32_t ma = (uint32_t)processed * units;

Parameters

type	Specifies what type of Motoron you are using.
referenceMv	The reference voltage (IOREF), in millivolts. For example, use 3300 for a 3.3 V system or 5000 for a 5 V system.

Definition at line 1837 of file Motoron.h.

◆ disableCommandTimeout()

void MotoronBase::disableCommandTimeout ( )

inlineinherited

This disables the Motoron's command timeout feature by resetting the the "Error mask" variable to its default value but with the command timeout bit cleared.

By default, the Motoron's command timeout will occur if no valid commands are received in 1500 milliseconds, and the command timeout is treated as an error, so the motors will shut down. You can use this function if you want to disable that feature.

Note that this function overrides any previous values you set in the "Error mask" variable, so if you are using setErrorMask() in your program to configure which status flags are treated as errors, you do not need to use this function and you probably should not use this function.

See also: setCommandTimeoutMilliseconds(), setErrorMask()

Definition at line 1107 of file Motoron.h.

◆ getStartingSpeedReverse()

uint16_t MotoronBase::getStartingSpeedReverse ( uint8_t motor )

inlineinherited

Reads the starting speed for the specified motor in the reverse direction.

For more information, see the "Starting speed reverse" variable in the Motoron user's guide.

See also: setStartingSpeed(), setStartingSpeedReverse()

Definition at line 864 of file Motoron.h.

◆ getStatusFlags()

uint16_t MotoronBase::getStatusFlags ( )

inlineinherited

Reads the "Status flags" variable from the Motoron.

The bits in this variable are defined by the MOTORON_STATUS_FLAG_* macros:

MOTORON_STATUS_FLAG_PROTOCOL_ERROR
MOTORON_STATUS_FLAG_CRC_ERROR
MOTORON_STATUS_FLAG_COMMAND_TIMEOUT_LATCHED
MOTORON_STATUS_FLAG_MOTOR_FAULT_LATCHED
MOTORON_STATUS_FLAG_NO_POWER_LATCHED
MOTORON_STATUS_FLAG_RESET
MOTORON_STATUS_FLAG_COMMAND_TIMEOUT
MOTORON_STATUS_FLAG_MOTOR_FAULTING
MOTORON_STATUS_FLAG_NO_POWER
MOTORON_STATUS_FLAG_ERROR_ACTIVE
MOTORON_STATUS_FLAG_MOTOR_OUTPUT_ENABLED
MOTORON_STATUS_FLAG_MOTOR_DRIVING

Here is some example code that uses C++ bitwise operators to check whether there is currently a motor fault or a lack of power:

uint16_t mask = (1 << MOTORON_STATUS_FLAG_NO_POWER) |
  (1 << MOTORON_STATUS_FLAG_MOTOR_FAULTING);
if (getStatusFlags() & mask) {  /* do something *&zwj;/ }

This library has helper methods that make it easier if you just want to read a single bit:

The clearLatchedStatusFlags() method sets the specified set of latched status flags to 0. The reinitialize() and reset() commands reset the latched status flags to their default values.

For more information, see the "Status flags" variable in the Motoron user's guide.

◆ getUARTErrorFlag()

bool MotoronBase::getUARTErrorFlag ( )

inlineinherited

Returns the "UART error" bit from getStatusFlags().

This bit is only relevant for the Motoron controllers with a UART serial interface.

For more information, see the "Status flags" variable in the Motoron user's guide.

If this flag is set, you might consider calling getUARTFaults() to get details about what error happened.

Definition at line 569 of file Motoron.h.

◆ getUARTFaults()

uint8_t MotoronBase::getUARTFaults ( )

inlineinherited

Returns the "UART faults" variable.

Every time the Motoron sets the "UART error" bit in the status flags register (see getUARTErrorFlag()) it also sets one of the bits in this variable to indicate the cause of the error.

The bits in this variable are defined by the MOTORON_UART_FAULT_* macros:

MOTORON_UART_FAULT_FRAMING
MOTORON_UART_FAULT_NOISE
MOTORON_UART_FAULT_HARDWARE_OVERRUN
MOTORON_UART_FAULT_SOFTWARE_OVERRUN

This function is only useful for Motorons with a UART serial interface.

This command is equivalent to briefly driving the Motoron's RST pin low. The Motoron's RST is briefly driven low by the Motoron itself as a result of this command.

After running this command, we recommend waiting for at least 5 milliseconds before you try to communicate with the Motoron.

See also: reinitialize()

Definition at line 406 of file Motoron.h.

◆ resetCommandTimeout()

void MotoronBase::resetCommandTimeout ( )

inlineinherited

Resets the command timeout.

This prevents the command timeout status flags from getting set for some time. (The command timeout is also reset by every other Motoron command, as long as its parameters are valid.)

		int16_t	speed2,
		int16_t	speed3
	)

inlineinherited

Sets the buffered speeds of all the motors.

The number of speed arguments you provide to this function must be equal to the number of motor channels your Motoron has, or else this command might not work.

This command does not immediately cause any change to the motors: it stores speed for each motor in the Motoron so they can be used by later commands.

This is equivalent to calling setBufferedSpeed() once for each motor, but it is more efficient because all of the speeds are sent in the same command.

For more information, see the "Set all speeds" command in the Motoron user's guide.

◆ setBraking()

void MotoronBase::setBraking	(	uint8_t	motor,
		uint16_t	amount
	)

inlineinherited

Commands the motor to brake, coast, or something in between.

Sending this command causes the motor to decelerate to speed 0 obeying any relevant deceleration limits. Once the current speed reaches 0, the motor will attempt to brake or coast as specified by this command, but due to hardware limitations it might not be able to.

The motor number parameter should be between 1 and the number of motors supported by the Motoron.

The amount parameter gets stored in the "Target brake amount" variable for the motor and should be between 0 (coasting) and 800 (braking). Values above 800 will be clipped to 800 by the Motoron firmware.

See the "Set braking" command in the Motoron user's guide for more information.

See also: setBrakingNow(), getTargetBrakeAmount()

Definition at line 1722 of file Motoron.h.

◆ setBrakingNow()

void MotoronBase::setBrakingNow	(	uint8_t	motor,
		uint16_t	amount
	)

inlineinherited

Commands the motor to brake, coast, or something in between.

Sending this command causes the motor's current speed to change to 0. The motor will attempt to brake or coast as specified by this command, but due to hardware limitations it might not be able to.

The motor number parameter should be between 1 and the number of motors supported by the Motoron.

The amount parameter gets stored in the "Target brake amount" variable for the motor and should be between 0 (coasting) and 800 (braking). Values above 800 will be clipped to 800 by the Motoron firmware.

◆ setProtocolOptions()

void MotoronBase::setProtocolOptions ( uint8_t options )

inlineinherited

Sends the "Set protocol options" command to the device to specify options related to how the device processes commands and sends responses. The options are also saved in this object and are used later when sending other commands or reading responses.

When CRC for commands is enabled, this library generates the CRC byte and appends it to the end of each command it sends. The Motoron checks it to help ensure the command was received correctly.

When CRC for responses is enabled, this library reads the CRC byte sent by the Motoron in its repsonses and makes sure it is correct. If the response CRC byte is incorrect, getLastError() will return a non-zero error code after the command has been run.

When the I2C general call address is enabled, the Motoron receives commands sent to address 0 in addition to its usual I2C address. The general call address is write-only; reading bytes from it is not supported.

By default (in this libary and the Motoron itself), CRC for commands and responses is enabled, and the I2C general call address is enabled.

This method always sends its command with a CRC byte, so it will work even if CRC was previously disabled but has been re-enabled on the device (e.g. due to a reset).

The options argument should be 0 or a combination of the following expressions made using the bitwise or operator (|):

(1 << MOTORON_PROTOCOL_OPTION_CRC_FOR_COMMANDS)
(1 << MOTORON_PROTOCOL_OPTION_CRC_FOR_RESPONSES)
(1 << MOTORON_PROTOCOL_OPTION_I2C_GENERAL_CALL)

For more information, see the "Set protocol optons" command in the Motoron user's guide.

◆ setProtocolOptionsLocally()

void MotoronBase::setProtocolOptionsLocally ( uint8_t options )

inlineinherited

Sets the protocol options for this object, without sending a command to the Motoron.

If the options you specify here do not match the actual configuration of the Motoron, future communication could fail.

Most users should use setProtocolOptions() instead of this.

The motor number should be between 1 and the number of motors supported by the Motoron.

The speed should be between -800 and 800. Values outside that range will be clipped to -800 or 800 by the Motoron firmware.

For single-channel Motorons, it is better to use setAllSpeeds() instead of this, since it sends one fewer byte.

◆ setVariable()

void MotoronBase::setVariable	(	uint8_t	motor,
		uint8_t	offset,
		uint16_t	value
	)

inlineinherited

Configures the Motoron using a "Set variable" command.

This library has helper methods to set every variable, so you should not need to call this function directly.

Parameters

motor	0 to set a general variable, or a motor number to set motor-specific variables.
offset	The address of the variable to set (only certain offsets are allowed).
value	The value to set the variable to.
