Constructor & Destructor Documentation

TB6612FNG ( PinName  pwm,
PinName  ctrl1,
PinName  ctrl2,
int  pwmPeriod = 100,
bool  brakeOnZeroDC = true 
)

Create TB6612FNG object connected to the specified mbed pins.

Parameters:
pwmPwmOut pin name
ctrl1/ctrl2DigitalOut control pin name
pwmPeriodsets the PWM period (µs)
brakeOnZeroDCtrue: The motor brakes on zero pulse width setting. false: The motor output is set to high impedance

Member Function Documentation

void brake (  )

brakes the motor by shorting it

Definition at line 54 of file TB6612FNG.cpp.

void off (  )

deactivates the motor (sets the motor output to high impedance, no short brake)

Definition at line 47 of file TB6612FNG.cpp.

void on (  )

activates the motor at the duty cycle selected with setPulseWidth()

Definition at line 27 of file TB6612FNG.cpp.

void operator= ( int  pw )

pulse width assignment

Parameters:
pwis the PWM pulse width setting in µs
See also:
setPulseWidth(int pw)

Definition at line 50 of file TB6612FNG.h.

void setPulseWidth ( int  pw )

Sets the PWM pulse width.

Parameters:
pwis the PWM pulse width setting in µs. The sign of the given pulsewidth defines the direction. With the default PWM period of 100µs (f=10kHz) this value is equivalent to the duty cycle.

Definition at line 18 of file TB6612FNG.cpp.

void setZeroDCReaction ( bool  brakeOnZeroDC )

set behaviour for zero DC setting

Parameters:
brakeOnZeroDCtrue: The motor brakes on zero pulse width setting. false: The motor output is set to high impedance

Definition at line 61 of file TB6612FNG.cpp.
