Hi, I'm Korean to use the tm4c123gh6pm.
I work with the processor.
I set the gpio port d pin 7 as button.
Actually, I set the buttons with gpio portd 4:7.
The buttons 4:6 is working very well.
But button that connects with gpio portd 7 isn't work.
I cannot find why
Ah, I'm using just chip with PCB not launch pad.
And I have tested with launch pad(tiva & stellaris)
In launch pad, there isn't the pins that are conneted with gpio portd 4:5.
In my simple test to test the buttons
When I set the buttons with gpio porte 0:3 with launchpad,
no problem happens. All buttons have worked very well.
But When I set the buttons with gpio portd 6:7 (launchpad do not support gpiod 4:6pins)
The buttons do not work.
What problem is related with portd?
Plz help me I want to know what's the problem..
But Im poor at english and data sheet.
