hi support team:

           Today，when i use GPIO A to read my key signal, i find it can't read it .but when i use GPIO B or C ,they all can read the signal,that's why?My core is v2.0.

               thanks!

Hi,

Your If statement is not correct,

if(GPIO_HAL_ReadPins(PTA)>> 1 == 0)‍

you should use something like this:

if((GPIO_HAL_ReadPins(PTA)) & (1 << 1))‍

Also, set direction registers:

GPIO_HAL_SetPinDirection(PTA,1,0);
GPIO_HAL_SetPinDirection(PTD,15,1);‍‍

Daniel
