.. _module-pw_i2c_mcuxpresso:
-----------------
pw_i2c_mcuxpresso
-----------------
``pw_i2c_mcuxpresso`` implements the ``pw_i2c`` interface using the
NXP MCUXpresso SDK.
The implementation is based on the i2c driver in SDK. I2C transfers use
non-blocking driver API.
Setup
=====
This module requires following setup:
1. Use ``pw_build_mcuxpresso`` to create a ``pw_source_set`` for an
MCUXpresso SDK.
2. Include the i2c driver component in this SDK definition.
3. Specify the ``pw_third_party_mcuxpresso_SDK`` GN global variable to specify
the name of this source set.
4. Use ``pw::i2c::McuxpressoInitiator`` implementation of
``pw::i2c::Initiator`` while creating ``pw::i2c::Device`` or
``pw::i2c::RegisterDevice`` interface to access the I2C devices connected to
target.
