    LPC1768 UART peripheral without RXD pin assignment

    I am facing a situation where I have one UART which is only used for Transmission. There is no requirement for RX functionality. I am using UART2. For this UART there are only two possible pin allocation for TXD & RXD. The first pair P0.10 & P0.11 is used for I2C functionality so I am left with P2.8 & P2.9 option only. Pin P2.9 is used as USB_CONNECT. As mentioned I have no RX functionality from the attached peripheral so I intend to use its TXD to do the transmission task and would like to have no assignment for RXD2 functionality. Is it possible to have UART without RXD pin assignment ?

    yes possible defiantly. please disable the ISR or interrupt for rxd.
    Please marked the thread solved if your problem is answered it will take few seconds of you but saves lot of time for others to get answers for same problems..
