CCS/LAUNCHXL-CC1352R1: Help with GPIO

LAUNCHXL-CC1352P: GPIO driver calls not working with CC1352P-2 board

Part Number: LAUNCHXL-CC1352P
Other Parts Discussed in Thread: CC1352P

I was trying to set/clear DIO19  pin using the following code: but it has no effect on the pin status.

GPIO_init();

GPIO_setConfig(19, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_HIGH);
GPIO_write(19, 1);
Same thing is working for the LED pin(DIO6)
Why it is not working with GPIO19 and 20 pins?

    Hi,

    I used the driverlibrary APIs to verify the hardware. It is working as expected.

    I left the DIO_19 in default configuration after device reset.

    see code below:

    //
    // Set GPIO as output
    //
    IOCPinTypeGpioOutput(IOID_19);
    GPIO_writeDio(IOID_19, 1);

    Regards,

    With LaunchPad projects and board files (CC1352P_2_LAUNCHXL.c), IOID_19 is assigned to the CC1352P_2_LAUNCHXL_UART0_CTS so make sure that UART, if enabled, is not interfering with this pin functionality.
