K64F I2C is it non blocking?

[haiqiwei]

Hi,

I want to implement I2C on K64F using KDS 3.0. But it is really slow. I suspected that it was waiting to read/send until the pkt is sent or read. Is there a non blocking implementation for it? Or is it already implemented?

Thanks,

Celine

Hello Haiqi

Are you using polling mode to transfer the data?  To free the resources for other application, please use the interrupt mode to transfer data.  You can find the example project for I2C application with interrupt mode under SDK 2.0 folder:

\SDK_2.0_FRDM-K64F\boards\frdmk64f\driver_examples\i2c

SDK 2.0 can be downloaded from:

Welcome to Kinetis Expert | Kinetis Expert

Please click on ‘Build an SDK’ to choose the FRDM-K64F board.  Then click on ‘Build SDK Package’ button and download the package.
