I2C Start sequence is coming properly but when I try to write byte send I am getting 'kStatus_I2C_Nak' error code and in I2C status register bit MSTSTATE is 3.</P><P></P><P>---</P></BODY></HTML> Thu, 24 May 2018 07:50:02 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC5411x-I2C-issue/m-p/718844#M29071 domneck 2018-05-24T07:50:02Z Re: LPC5411x I2C issue https://community.nxp.com/t5/LPC-Microcontrollers/LPC5411x-I2C-issue/m-p/718845#M29072 <HTML><HEAD></HEAD><BODY><P>Hi customer,</P><P>&nbsp;&nbsp; Check the I2C bus wave, then check whether the I2C slave(sensor) give ACK?</P><P>&nbsp;&nbsp; If the slave didn't ACK, it means the I2C baudrate or the wave or the data didn't meet the slave demand, you also need to check the slave datasheet.</P><P></P><P>Wish it helps you!<BR />Have a great day,<BR />Kerry</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
