pub struct Port<MODE> { /* private fields */ }

Implementations

impl Port<()>

pub fn new(gpio: PortNum, mask: u16, regs: &'static PortReg) -> Self

Creates a new GPIO port instance.

Arguments

• gpio - The port number.
• mask - A bit mask specifying which pins are part of this port.

Returns

A new Port instance with uninitialized mode.

pub fn into_input(&self, mode: PortModeInput) -> Port<InputPort>

Converts the port to an input mode.

Arguments

• mode - The input mode configuration.

Returns

A new Port instance configured as an input port.

pub fn into_output(&self, mode: PortModeOutput) -> Port<OutputPort>

Converts the port to an output mode.

Arguments

• mode - The output mode configuration.

Returns

A new Port instance configured as an output port.

impl Port<OutputPort>

pub unsafe fn set_bits_uncheck(&mut self, bits: u16)

Sets the specified bits of the output register without checking bounds or validity.

Safety

This function must only be called when it is safe to modify the output register directly.

pub unsafe fn clr_bits_uncheck(&mut self, bits: u16)

Clears the specified bits of the output register without checking bounds or validity.

Safety

This function must only be called when it is safe to modify the output register directly.

pub unsafe fn read_output_bits_uncheck(&mut self) -> u16

Reads the current value of the output register without checking bounds or validity.

Safety

This function must only be called when it is safe to read from the output register directly.

pub unsafe fn write_bits_uncheck(&mut self, bits: u16)

Writes a value to the output register without checking bounds or validity.

Safety

This function must only be called when it is safe to modify the output register directly.

pub fn set_bits(&mut self, bits: u16)

Sets the specified bits of the output register, applying the bit mask.

pub fn clr_bits(&mut self, bits: u16)

Clears the specified bits of the output register, applying the bit mask.

pub fn read_output_bits(&mut self) -> u16

Reads the current value of the output register, applying the bit mask.

pub fn write_bits(&mut self, bits: u16)

Writes a value to the output register, applying the bit mask.

pub fn read_input_bits(&mut self) -> u16

Reads the current value of the input register, applying the bit mask.

impl Port<InputPort>

pub unsafe fn read_input_bits_uncheck(&mut self) -> u16

Reads the current value of the input register without checking bounds or validity.

Safety

This function must only be called when it is safe to read from the input register directly.

pub fn read_input_bits(&mut self) -> u16

Reads the current value of the input register, applying the bit mask.
