i2c_msg Struct Reference

One I2C Message. More...

#include <i2c.h>

Data Fields
uint8_t *	buf
	Data buffer in bytes.
uint32_t	len
	Length of buffer in bytes.
uint8_t	flags
	Flags for this message.

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.
