CHIPBoardInfo

public CHIPBoardInfo()

Method Details

populateBoardPinInfo

public void populateBoardPinInfo()

Description copied from class: BoardInfo

Pin initialisation is done separately to the constructor since all known BoardInfo instances get instantiated on startup by the Java ServiceLoader.

Overrides:

populateBoardPinInfo in class GenericLinuxArmBoardInfo

mapToSysFsGpioNumber

public int mapToSysFsGpioNumber(int gpio)

Overrides:

mapToSysFsGpioNumber in class BoardPinInfo

getPwmChip

public int getPwmChip(int pwmNum)

Description copied from class: BoardInfo

Get the PWM chip for the specified PWM number. Only actually relevant for sysfs PWM control on the BeagleBone Black.

Overrides:

getPwmChip in class BoardInfo

Parameters:

pwmNum - The sysfs PWM channel number

Returns:

The PWM chip number for the requested PWM channel number, -1 if not found / not relevant

createMmapGpio

public MmapGpioInterface createMmapGpio()

Description copied from class: BoardInfo

Instantiate the memory mapped GPIO interface for this board. Not that the caller needs to call initialise prior to use.

Overrides:

createMmapGpio in class BoardInfo

Returns:

the MMAP GPIO interface implementation for this board, null if there isn't one
