I am facing tricky problem with Kinetis I2C.&nbsp; I am using Kinetis I2C_LDD Component for I2C communication. It is working fine for some time, after some time I2C is always showing I2C Bus Busy state.There on wards i am unable to send/receive any data on that bus. Please provide the sequential procedure to recover the I2C from Busy state to Idle state. </SPAN></P><P></P><P><SPAN style="font-family: 'book antiqua', palatino;">Regds</SPAN></P><P><SPAN style="font-family: 'book antiqua', palatino;">Dhruvonline</SPAN></P></BODY></HTML> Sat, 19 Jul 2014 18:02:22 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Reset-Kinetis-I2C-BUS/m-p/322503#M14603 dhruvonline 2014-07-19T18:02:22Z Re: Reset Kinetis I2C BUS https://community.nxp.com/t5/Kinetis-Microcontrollers/Reset-Kinetis-I2C-BUS/m-p/322504#M14604 <HTML><HEAD></HEAD><BODY><P>Hi</P><P></P><P>Maybe the following could help?</P><P><A href="https://community.nxp.com/message/398627">I2C device dead-lock recovery</A></P><P></P><P>There are however many PE/I2C threads with various difficulties (do a forum search for "I2C PE" for a list of posts to study) that have been analysed.
