Dear Team,
I am using TLIN1027-Q1 transceiver to support K-line.
I have attached the schematics snap shot of the TLIN1027-Q1 for your reference.
Test setup:
I am interfacing TLIN1027-Q1 through UART to the host processor and the 6th pin of the TLIN1027-Q1 I have connected to ECUSIM2000 simulator where k-line is supported.
We are trying to send the data from the device in which transceiver is mounted to the K-line simulator.
As per k-line protocol we need to send the request from the device and get an acknowledgement from the ECU (in my case simulator) to initiate the data communication.
I this case I am not sure whether the proper response is coming from the device. I think I am getting same message what i transmit.
I have probed and attached the graphs of the UART_TX, UART_RX and K-line pins of the transceiver.
Please go though this and let me know if I am missing out something.
With regards,
Jayashree.
