GPIO

###Description GPIO Interface - This interface allows manipulation of OpenVCI Kit's GPIO pins.

Class

GPIO

Structures and enumerations

enum Type{DIGITAL_IN = 0, DIGITAL_IN_PULLUP, DIGITAL_OUT}

Type - Pin mode types

• DIGITAL_IN - digital input mode
• DIGITAL_IN_PULLUP - digital input with pullup
• DIGITAL_OUT - digital output mode

Public member functions

GPIO()

Constructor - initializes the pins and other variables

---

void setType(byte pin, Type type)

Allows setting of the type i.e. INPUT or OUTPUT of an individual GPIO pin.
Arguments:

• pin (Type: byte) - the GPIO pin number
• type(Type: Type) - type to be set for the pins

---

void setType(byte from, byte to, Type type)

Allows setting of the type i.e. INPUT or OUTPUT of a range of GPIO pins.
Arguments

• from (Type: byte) - starting GPIO pin number
• to (Type: byte) - ending GPIO pin number
• type(Type: Type) - type to be set for the pins

---

void writeDigital(byte from, byte to, boolean value)

Set/Reset a range of GPIO pins in digital mode.
Arguments:

• from (Type: byte) - starting GPIO pin number
• to (Type: byte) - ending GPIO pin number
• value(Type: boolean) - High / Low

---

void writeDigital(byte pin, boolean value)

Set/Reset an individual GPIO in digital mode.
Arguments:

• pin (Type: byte) - the GPIO pin number
• value (Type: boolean) - High / low

---

void writePWM(byte from, byte to, byte value)

Set/Reset a range of GPIO pins in PWM mode.
Arguments:

• from (Type: byte) - starting GPIO pin number
• to (Type: byte) - ending GPIO pin number
• value(Type: byte) - PWM Value (0-255)

---

void writePWM(byte pin, boolean value)

Set/Reset an individual GPIO in PWM mode.
Arguments:

• pin (Type: byte) - the GPIO pin number
• value (Type: byte) - PWM Value (0-255)
