Fields
| Name | Value | Description |
|---|---|---|
| Exclusive | 0 | Connects to the I2 C bus address exclusively, so that no other connection to the I2 C bus address can be made while you remain connected. This mode is the default mode. |
| Shared | 1 | Connects to the I2 C bus address in shared mode, so that other connections to the I2 C bus address can be made while you remain connected. You can perform all operations on shared connections, but use such connections with care. When multiple client apps change the global state of the I2 C device, race conditions can result. An example use case for using a shared connection is a sensor that obtains readings without changing the state of the device. |
