Hello.
I am developing a LIN master board using TJA1020.
In the case of TX, it signals normally and the slave also operates normally.
The problem is that when ID values are sent to receive responses, the response from the slave does not come to RX.
When analyzing the signal of the LIN line, the slave responds normally.
However, there is no signal from the RX pin of the TJA1020.
Please let me know which part I missed.
Hello Miri,
Please double check that the TJA1020 is in normal slope mode:
BR, Tomas
