|
<p>The MCUXpresso SDK provides a peripheral driver for I2C master function using Flexible I/O module of MCUXpresso SDK devices.</p>
|
|
<p>The FlexIO I2C master driver includes functional APIs and transactional APIs.</p>
|
|
<p>Functional APIs target low level APIs. Functional APIs can be used for the FlexIO I2C master initialization/configuration/operation for the optimization/customization purpose. Using the functional APIs requires the knowledge of the FlexIO I2C master peripheral and how to organize functional APIs to meet the application requirements. The FlexIO I2C master functional operation groups provide the functional APIs set.</p>
|
|
<p>Transactional APIs target high-level APIs. The transactional APIs can be used to enable the peripheral quickly and also in the application if the code size and performance of transactional APIs satisfy the requirements. If the code size and performance are critical requirements, see the transactional API implementation and write custom code using the functional APIs or accessing the hardware registers.</p>
|
|
<p>Transactional APIs support an asynchronous transfer. This means that the functions <a class="el" href="a00031.html#ga4e21323685831e0ee3f88d50e4c8872c" title="Performs a master interrupt non-blocking transfer on the I2C bus. ">FLEXIO_I2C_MasterTransferNonBlocking()</a> set up the interrupt non-blocking transfer. When the transfer completes, the upper layer is notified through a callback function with the kStatus_Success status.</p>
