GPIO_PinConfig, GPIO_setConfig and MSP432 launchpad

Anders Dam Kofoed

I am having trouble finding an example on how to use the new GPIO_setConfig in TI-RTOS 2.12 using the MSP432 launchpad and CCS.

I have read the migration guide on the wiki but the example is not for ARM.

Say I wanted just to set an outputpin high (say P1.6). How would I do that?

I suspect something like the following, but the function would like a pin-number but then what about the port?

GPIO_PinConfig gpioOUT = GPIO_CFG_OUT_STD | GPIO_CFG_OUT_STR_HIGH | GPIO_CFG_OUT_HIGH;
GPIO_setConfig(???, gpioOUT);

On ARM we need to specify both port and pin.

Kind regards

Got it,
Basically, in included MSP_EXP432P401RLP.c file, I did not see the config as the doc says. This array is a global array and used during init.

This was what I added to get it working:

GPIO_PinConfig gpioPinConfigs[] = {
...
GPIOMSP432_P1_6 | GPIO_CFG_OUT_STD | GPIO_CFG_OUT_STR_HIGH | GPIO_CFG_OUT_LOW
...
}
