i2c_dma_transfer

Overview

The i2c_dma example shows how to use I2C driver in DMA way:

In this example , one i2c instance used as I2C master and another i2c instance used as I2C slave .

1. I2C master send data to I2C slave with DMA . (I2C Slave using interrupt to receive the data)

2. I2C master read data from I2C slave with DMA . (I2C Slave using interrupt to send the data)
