Original question:

CC1310: Setup UART RX pin with External Pull-Up

SIMPLELINK-LOWPOWER-F2-SDK: Option to Setup UART-RX-Pin with internal Pullup

Part Number: SIMPLELINK-LOWPOWER-F2-SDK
Other Parts Discussed in Thread: SYSCONFIG

Is there a plan to extend the UART configuration options so that a pull-up or pull-down resistor for the RX pin can be selected in SysConfig?
This refers to the pull resistor while the UART is open.

    Hi Niko,

    It is unlikely that SysConfig or the UART2 TI Driver will be modified to accommodate this request.  You can apply the pin change you desire manually by changing the hwAttrs->rxPin from GPIO_CFG_INPUT to GPIO_CFG_IN_PU in <sdk_install_directory>/source/ti/drivers/uart2/UART2CC26X2.c inside of the UART2CC26X2_initIO function.  You can copy a version of UART2CC26X2.c locally into your project workspace and apply changes there so that the original is not modified to unintentionally affect other projects referencing that file.

    Regards,
    Ryan
