K142 LIN

[steve007]

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)

Hi,

not sure of exact example you are referring to. 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.
