Here it seems a LIN transceiver is not active, so be sure board is powered by 12V and transceiver's SLP pin is held high by MCU.</P><P>BR, Petr</P> Mon, 27 May 2024 06:15:58 GMT PetrS 2024-05-27T06:15:58Z https://community.nxp.com/t5/S32K/K142-LIN/m-p/1874978#M35791 <P><SPAN>I am using the K142EVB-Q100 development board and S32DS IDE. However, when I download the official demo and act as the master node, I can't capture the LIN frame header with an oscilloscope on the LIN line; there is only a continuous high level. When I measure the LIN TX pin directly, there is a signal, but it is still not the waveform of the frame header.I don't know why?(the photo is LIN-TX)<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Cache_-1c6c9325d565cf8d.jpg" style="width: 450px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/280834i580DB828EC0F377C/image-size/large?v=v2&amp;px=999" role="button" title="Cache_-1c6c9325d565cf8d.jpg" alt="Cache_-1c6c9325d565cf8d.jpg" /></span></SPAN></P> Sat, 25 May 2024 07:53:19 GMT https://community.nxp.com/t5/S32K/K142-LIN/m-p/1874978#M35791 steve007 2024-05-25T07:53:19Z https://community.nxp.com/t5/S32K/K142-LIN/m-p/1875231#M35808 <P>Hi,</P><P>not sure of exact example you are referring to.
