CC3220S-LAUNCHXL: How do you program a GPIO correctly.

Hi,

I am trying to add another GPIO to the this launch pad project.

I have done the following:

Placed: GPIOCC32XX_GPIO_12 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_STR_HIGH | GPIO_CFG_OUT_HIGH in gpioPinConfigs[] at index 5 in CC3220s_LaunchXL.c file and added it to GPIOName enum at index 5 as well in CC3220s_LaunchXL.h file.

Is this all that is needed? I didnt not do a GPIO_Write to make it a '1' because I defaulted it to be high:

GPIOCC32XX_GPIO_12 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_STR_HIGH | GPIO_CFG_OUT_HIGH

GPIO_12 is Pin 3 on the Part.

What am I missing?

I have been able to successfully initialize and program all GPIOs on my system with the exception of this Pin. We are investigating this issue from a hardware perspective .

Hi Ozzy,

Please use the latest SDK, which comes with SysConfig. This tool helps simplify peripheral configuration, including GPIOs.

Follow the SysConfig SimpleLink Academy lab if you haven't used it before.

Seong
