HI

In myUART_5529.zip, (MSP-EXP430FR5969 LaunchPad), file myGpio.c, line 62, should

    GPIO_setAsPeripheralModuleFunctionOutputPin(
       		myUart.Channels[0].RxPort,
        	myUart.Channels[0].RxPin,
        	myUart.Channels[0].RxSel

not be

    GPIO_setAsPeripheralModuleFunctionInputPin(
       		myUart.Channels[0].RxPort,
        	myUart.Channels[0].RxPin,
        	myUart.Channels[0].RxSel

Thanks 

Nick

    Hi Nick,

    You will find in the MSP430FR5969 datasheet that the PxDIR register bits (changed depending on output or input pin notation) is "Don't care" for eUSCI functionality as the direction is controlled by the module itself.

    Regards,
    Ryan
