Implements FOCDriver.

Definition at line 44 of file BLDCDriver3PWM.cpp.

Here is the call graph for this function:

setPhaseState()

void BLDCDriver3PWM::setPhaseState ( PhaseState  sa, PhaseState  sb, PhaseState  sc  )

overridevirtual

Set phase voltages to the hardware

‍Only possible is the driver has separate enable pins for all phases!

Parameters

sc	- phase A state : active / disabled ( high impedance )
sb	- phase B state : active / disabled ( high impedance )
sa	- phase C state : active / disabled ( high impedance )

Implements BLDCDriver.

Definition at line 67 of file BLDCDriver3PWM.cpp.

setPwm()

void BLDCDriver3PWM::setPwm ( float  Ua, float  Ub, float  Uc  )

overridevirtual

Set phase voltages to the hardware

Parameters

Ua	- phase A voltage
Ub	- phase B voltage
Uc	- phase C voltage

Implements BLDCDriver.

Definition at line 77 of file BLDCDriver3PWM.cpp.
