Detailed Description

One I2C Message.

This defines one I2C message to transact on the I2C bus.

Note
Some of the configurations supported by this API may not be supported by specific SoC I2C hardware implementations, in particular features related to bus transactions intended to read or write data from different buffers within a single transaction. Invocations of i2c_transfer() may not indicate an error when an unsupported configuration is encountered. In some cases drivers will generate separate transactions for each message fragment, with or without presence of I2C_MSG_RESTART in flags.
