Dear Team,

We have implemented two analog reading at port 2.0 port 2.1 via sequencer. and one through ESM  

now we required to take one more analog channel reading via sequencer at port 2.2, but once we do it disturb the LIN communication.

any suggestion or advice will be helpful.

Hi @RJ_0701 ,

Could you please provide more details on what you mean by "it disrupts the LIN communication", when you are going from sequencer mode to ESM and back to sequencer mode?

Best Regards,

Hello Sahil, Let I Frame my question again: We are reading the analog signal using port 2.0 and 2.1 using sequencer, also port 2.1 is configured as ESM with timer 3 as triggered, with this configuration all reading is ok and LIN communication is working well,

Now when we connect one more analog signal to port 2.2 using sequencer, the observation is LIN communication get affected.

so, is there any tradeoff between number of analog signal reading and LIN communication?

Hi @RJ_0701 ,

ADC and LIN are two separate blocks, and the communication on LIN should not be affected by the ADC. Could you kindly verify the configuration and schematic to ensure that everything is in order? In case the issue continues, please share the project file and schematic with us.

Best Regards,
Sahil Kumar
