Detailed Description

I2C transaction.

This structure defines an I2C transaction. It specifies the buffer(s) and buffer size(s) to be written to and/or read from an I2C slave peripheral. arg is an optional user-supplied argument that will be passed to the user-supplied callback function when the I2C driver is in I2C_MODE_CALLBACK. nextPtr is a pointer used internally by the driver for queuing of multiple transactions; this value must never be modified by the user application.

void* I2C_Transaction_::readBuf

Buffer to which data is to be read into

§ readCount

size_t I2C_Transaction_::readCount

Number of bytes to be read from the slave

§ slaveAddress

uint_least8_t I2C_Transaction_::slaveAddress

Address of the I2C slave peripheral

§ arg

void* I2C_Transaction_::arg

Argument to be passed to the callback function

§ nextPtr
