MSP432E411Y: How to reverse the logic of UART

K.Z
Expert 2570 points
Part Number: MSP432E411Y

Tool/software:

Hi All,

I am trying to communicate via UART and XP1001000-05R (Lantronix XPort) via RS232C.
I want to reverse the logic of the MSP432 UART, but I don't know how to configure it.
Please let me know if you have any sample code.
Is it necessary to reverse the logic on the XPort side?

Best Regards,

Ito

    Hi Ito-san,

      I'm not clear with your question as to reverse the logic for the MSP432E UART. Are you talking about the capability to swap UARTTX and UARTRX pin, perhaps due to an incorrect connections between the MCU and XP1001000-05R? If this is your question, then no. There is no such programmability to swap between the pin function between UARTTX and UARTRX. 

      Please refer to the example at C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\driverlib\uart_echo for reference.
