I am using the Serial_LDD but need to enable TXRTSE. How do I do that?

[tomtalkington]

I plan to use the Serial_LDD with a UART for RS485.  I need to enable TXRTSE but don't see a way to in the LDD properties.  It is settable in the Init_UARTof Hardware Initialization.  Can the Init_UART be used with the Serial_LDD?  If so how do I do this?

Hi Tom,

The Init_UART and Serial_LDD components cannot be used for the same peripheral at the same time, you can only use one of them. Another option is to create a Processor Expert project with KSDK and use the fsl_uart component  together with the fsl_uart_hal and enable RTS/CTS by using of RTS/CTS functions, you can find more information on this thread:

Does the Processor Expert UART component allow usage of RTS?

Hope it helps!
