I have TWR-S12G128. I am not able to get the LIN Tx data on pin no.2 of COM_EN (Also checked on Pin no. 1). To see the data is receiving or not I have connected Oscilloscope probe to Pin no. 2 of COM_EN and continuously sending data on the LIN bus.
Following settings I have made
1. I have connected LIN Bus to Pin no. 4 of J6. (Pin 1,2,3 are kept open)
2. Pin no. 1-2,3-4 of JP3 LIN_PWR are short.(no slave is connected,no external supply is given).
3. SW6 is ON.
4. All Pins of COM_EN are kept open. (Just want to see data is receiving or not at the pin).
5. PWR_SEL JP5 Pin no. 3-4 are short.
Please suggest to get the data.
