Constructor & Destructor Documentation

UHS2_GPIO()

UHS2_GPIO::UHS2_GPIO

(

USB *

pUsb

)

Implement an instance of a UHS2_GPIO object.

Parameters

pUSB	Pointer to a UHS2 USB object

Definition at line 32 of file UHS2_gpio.cpp.

Member Function Documentation

digitalWrite()

void UHS2_GPIO::digitalWrite	(	uint8_t	pin,
		uint8_t	val
	)

Set a GPIO output value.

Parameters

pin	GPIO output pin on USB Host Shield to set
val	Value to set the pin to (zero value will clear output, non-zero value will assert output)

Definition at line 40 of file UHS2_gpio.cpp.

digitalRead()

int UHS2_GPIO::digitalRead

(

uint8_t

pin

)

Read the value from a GPIO input pin.

Parameters

pin	GPIO input pin on USB Host Shield to read

Return values

int	Value of GPIO input (-1 on fail)

Definition at line 55 of file UHS2_gpio.cpp.

digitalReadOutput()

int UHS2_GPIO::digitalReadOutput

(

uint8_t

pin

)

Read the value from a GPIO output pin.

Parameters

pin	GPIO output pin on USB Host Shield to read

Return values

int	Value of GPIO output (-1 on fail)

Note

Value of MAX3421E output register, i.e. what the device has been set to, not the physical value on the pin
