Tool/software:
My Program has complied successfully and Same has been loaded and Debug in to CC1312R1 LaunchXLsystem.
I have configured my GPIO in .syscfg file.
Problem: I am not able to see live view of my physical IO status in live at CCS. I tired with view >register , View> Expressions DOUT15_12 or DIN31_0. but no result.
Please Resolve the issue.
The do not knwo what the code you have posted above is suppose to do, as these are not functions call that I can find in the SDK.
Please use the GPIO driver to control the GPIO.
I took the empty_CC1312R1_LAUNCHXL_freertos_gcc example from the latest SDK and added GPIO12 and GPIO15 in sysconfig:
I then modified the code to set and clear these GPIOs, together with the GPIO already used in the example (CONFIG_GPIO_LED_0).
I did not havea ny issues debugging the signals using CCS and watching the signals be set and cleared as I stepped through the code.

Hi Siri,
i tried one example of GPIO Interrupt, but still facing same issue. i am sharing code of the sample example program with screen shots of CCS.

MY Program is executing successfully on CC1312R1 Launch XL Board. but still I am not able to see Live GPIO status in my system.
pls advice what to do.
