Trouble with GPIO_PinInit()

tcwong — Wed, 17 Jul 2019 18:00:33 GMT

I want to use the function GPIO_PinInit to initialize the PTA7 (located in GPIOA). I am using GPIO_PinInit(GPIOA, 7u, &output_config) and I keep getting errors. I already have output_config defined with

gpio_pin_config_t = {

kGPIO_DigitalOutput,

What am I missing? The issue seems to be with GPIOA part of my function.

Hello Tyler,

Could you please specify the MCU you are working on? Also, I need to know the errors you are having. Could you please attach a snippet?

Best regards,

Felipe

Hello Felipe,

I actually figured out the issue I was having. The first part of the function I should have been using kPGIO_PORTA from the SDK i downloaded. Thanks for trying to help though!

Best,

Tyler

Hi Tyler,

just a note - there is also supported Pins tool allowing to generate pins configuration for you. The Pins tool cis integrated directly in MCU IDE or available in standalone MCUXpresso Config Tools.
