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?</P><P></P><P>Thanks,</P><P>Celine</P></BODY></HTML> Mon, 06 Jun 2016 15:47:16 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/K64F-I2C-is-it-non-blocking/m-p/515446#M32600 haiqiwei 2016-06-06T15:47:16Z Re: K64F I2C is it non blocking? https://community.nxp.com/t5/Kinetis-Microcontrollers/K64F-I2C-is-it-non-blocking/m-p/515447#M32601 <HTML><HEAD></HEAD><BODY><P>Hello Haiqi</P><P></P><P><SPAN style="font-family: 'Arial','sans-serif';">Are you using polling mode to transfer the data?&nbsp; To free the resources for other application, please use the interrupt mode to transfer data.&nbsp; You can find the example project for I2C application with interrupt mode under SDK 2.0 folder: </SPAN></P><P><SPAN style="font-family: 'Arial','sans-serif';">\SDK_2.0_FRDM-K64F\boards\frdmk64f\driver_examples\i2c</SPAN></P><P></P><P><SPAN style="font-family: 'Arial','sans-serif';">SDK 2.0 can be downloaded from:</SPAN></P><P><SPAN style="font-family: 'Arial','sans-serif';"><A href="http://kex.freescale.com/en/welcome" title="http://kex.freescale.com/en/welcome">Welcome to Kinetis Expert | Kinetis Expert</A> </SPAN></P><P></P><P><SPAN style="font-family: 'Arial','sans-serif';">Please click on ‘Build an SDK’ to choose the FRDM-K64F board.&nbsp; Then click on ‘Build SDK Package’ button and download the package. </SPAN></P><P></P><P></P><P></P><P>Best Regards</P><P>Fiona Kuang</P><P>TIC - Technical Information Center</P><P>-----------------------------------------------------------------------------------------------------------------------</P><P>Note: If this post answers your question, please click the Mark Correct button.
