Do you have some better picture of the screen? That one is not readable.</P><P>Also FlexRay bus uses differential signaling, so it's better to measure both of them and subtract them. Measuring of single ended signal is possible too but it's not precise.</P><P></P><P>Regards,</P><P>Lukas</P></BODY></HTML> Tue, 11 Aug 2020 05:49:51 GMT https://community.nxp.com/t5/MPC5xxx/FlexRay-Wake-Up-pattern/m-p/1074113#M16143 lukaszadrapa 2020-08-11T05:49:51Z
