BricktronicsMotor v1.2 - A software library for LEGO NXT motors.
More details at http://www.wayneandlayne.com/bricktronics/
- Click the "Clone or download" button on the upper-right side of this page below the pink bar, then select "Download ZIP". Rename the uncompressed folder BricktronicsMotor. Check that the BricktronicsMotor folder contains BricktronicsMotor.cpp and BricktronicsMotor.h
- Place the BricktronicsMotor library folder into your
<arduinosketchfolder>/libraries/folder. You may need to create the libraries subfolder if this is your first installed library. Restart the Arduino IDE.
BricktronicsMotor(uint8_t enPin, uint8_t dirPin, uint8_t pwmPin, uint8_t encoderPin1, uint8_t encoderPin2)- Constructor
void begin(void)- Call the begin function in your setup() function
void coast(void)- Let the motor coast
void brake(void)- Rapidly slow down the motor
void hold(void)- Stop the motor and hold it in place
void update(void)- Recalculate the PID motor control parameters
void setFixedDrive(int16_t speed)- Raw, uncontrolled motor speed setting
void goToPosition(int32_t position)- Uses PID algorithm to drive motor to position
void goToPositionWaitForDelay(int32_t position, uint32_t delayMS)- Same as goToPosition but wait for delayMS
void goToPositionWaitForArrival(int32_t position)- Same as goToPosition but wait for arrival. May get stuck if motor never arrives...
bool goToPositionWaitForArrivalOrTimeout(int32_t position, uint32_t timeoutMS)- Same as above but will timeout after timeoutMS.
void goToAngle(int32_t angle)- There is a whole family of functions for moving to an angle (0 - 355 degrees)
void pidSetTunings(double Kp, double Ki, double Kd)- Update the PID tuning parameters
bool settledAtPosition(int32_t position)- Check if the motor has reached the desired position, accounting for PID output and a deadband around the desired position.
