Set GPIO

stdcerr — Wed, 14 Oct 2020 23:09:16 GMT

Hi,

I'm back at the very basics, why do my GPIOs PORTC15 & PORTC18 not get set high with the following code?

gpio_pin_config_t ConfigC15 = { .pinDirection = kGPIO_DigitalOutput, .outputLogic = 0 }; gpio_pin_config_t ConfigC18 = { .pinDirection = kGPIO_DigitalOutput, .outputLogic = 0 }; GPIO_PinInit(GPIOC,15,&ConfigC15); GPIO_PinInit(GPIOC,18,&ConfigC18); GPIO_PinWrite(GPIOC,15,1); GPIO_PinWrite(GPIOC,18,1);

What am I missing?

Same resiult when I set the default outputLogic to 1 instead.

Hm, I added

CLOCK_EnableClock(kCLOCK_PortC);

before the lines above but still no luck.

Hi,

Which mcu do you use? Do you configure the pin multiplexing? Configure the pin as GPIO ? The sdk has gpio example. You can refer it.

Have a great day,
