Struct Iocon 

pub struct Iocon { /* private fields */ }

Implementations

impl Iocon

pub const fn new() -> Self

pub fn configure_pin(&self, pin: LPCPin, config: Config)

Configures the function, pull mode, and digital mode of a given pin.

Overview

This function applies a standard configuration value to the selected pin, based on the provided Config settings:

• function: the peripheral function assigned to the pin
• pull: the pull-up/pull-down resistor configuration
• digital_mode: whether the pin is used in digital mode

Current Limitations

At the moment, only GPIO and alarm functionality are supported. Many pins are commented out in the match statement because they belong to peripherals (e.g., UART, SPI, I2C, etc.) that are not yet implemented. These pins will require additional configuration logic once their corresponding peripheral drivers are added.

Notes

• Pins such as P1_4 (on-board blue LED) and P1_9 (user button) are already supported for basic GPIO usage.
• Attempting to configure a pin that is not yet implemented will result in no action (_ => {} branch).

Future Work

As new peripherals are implemented for the lpc55sx, the commented-out pin entries will be enabled and configured accordingly.

Example

// Configure P0_0 as a GPIO output with pull-up enabled
device.configure_pin(LPCPin::P0_0, Config {
    function: Function::Gpio,
    pull: Pull::Up,
    digital_mode: DigitalMode::Enabled,
});

pub fn set_pull_none(&self, pin: LPCPin)

pub fn set_pull_up(&self, pin: LPCPin)

pub fn set_pull_down(&self, pin: LPCPin)
