PI4IOE5V6408 “Low-voltage Translating 8-bit I2C-bus I/O Expander”

Implementations

impl<I2C> Pi4ioe5v6408<RefCell<Driver<I2C>>>

where I2C: I2cBus,

pub fn new(i2c: I2C, addr: bool) -> Result<Self, I2C::BusError>

Create a new driver for the PI4IOE5V6408 “Low-voltage Translating 8-bit I2C-bus I/O Expander” All pins will be configured as floating inputs

Arguments

• i2c - The I2C bus the device is connected to
• addr - The address of the device. The address is 0x43 if addr is false and 0x44 if addr is true

impl<I2C, M> Pi4ioe5v6408<M>

where I2C: I2cBus, M: PortMutex<Port = Driver<I2C>>,

pub fn with_mutex(i2c: I2C, addr: bool) -> Result<Self, I2C::BusError>

Create a new driver for the PI4IOE5V6408 “Low-voltage Translating 8-bit I2C-bus I/O Expander” with a mutex. All pins will be configured as floating inputs

Arguments

• i2c - The I2C bus the device is connected to
• addr - The address of the device. The address is 0x43 if addr is false and 0x44 if addr is true

pub fn with_retained_pin_config( i2c: I2C, addr: bool ) -> Result<Self, I2C::BusError>

Create a new driver for the PI4IOE5V6408 “Low-voltage Translating 8-bit I2C-bus I/O Expander” retaining the previous (pullup/down and interrupt) configuration.

Warning: Only use this constructor to recreate the driver for a chip that has been properly initialized before.

Arguments

• i2c - The I2C bus the device is connected to
• addr - The address of the device. The address is 0x43 if addr is false and 0x44 if addr is true
