Hi everyone,

I am trying to communicate with MCP2003 (LIN Transceiver) in UART via USB/UART CY7C65215.
Unfortunately I do not manage to create a correct LIN frame (Break/Sync/Message) because of Start/Stop bit automatically created by the component between every byte.

Is there a way to configure the CY7C65215 for deleting these bits ? I did not find anything in the datasheet.
(I am using the DLL given by cypress to Transmit and receive data)

Thank you for your help !

Hello,

There is no option for deleting the stop bits, you can configure the number of stop bits to 1 or 2 using the USB-Serial Configuration Utility in UART CDC or Vendor mode.

Please refer to the USB Serial configuration utility user guide and API documentation from the USB-Serial SDK for more information on how to configure the number of stop bits using APIs in the application as well.
