Expand description

Abstractions for managing I2C devices.

Structs

HwmonDeviceType
A basic (non-pmbus) hwmon I2C device type.
I2CDevice
An instantiated I2C device.
I2CDeviceParams
The information needed to instantiate an I2C device.
PMBusDeviceType
A PMBus I2C device type.

Enums

I2CDeviceType
An enum for an I2C device type.

Constants

I2C_DEV_DIR 🔒
The sysfs directory into which all i2c devices are mapped.

Statics

I2C_HWMON_DEVICES 🔒
A map of supported I2C device types.
I2C_PMBUS_TYPES 🔒
A set of device types known to be PMBus sensors.

Functions

get_device_type
Retrieve an I2CDeviceType for the given device type string.
get_i2cdev
Find an existing I2CDevice in devmap for the given params, or instantiate one and add it to devmap if not. Returns:

Type Definitions

I2CDeviceMap
Lookup table for finding I2CDevices. Weak<> because we only want them kept alive by (strong, Arc<>) references from Sensors so they get dropped when the last sensor using them goes away.
