STM32WBA55 Example - How to handle pins in reset state?

[ledi001]

Hi,

i am using CubeIDE 1.16.1 and if i import the BLE_p2pServer example for NUCLEO-WBA55CG, a few pins (GPIOs for LEDs and buttons) are marked in reset state.

Can somebodey explain why they are in reset state and not in GPIO_Input or GPIO_Output?

Hello @ledi001 

First let me thank you for posting.

Actually I checked the generated code for both LED and button configuration 

 GPIO_Init.Pin = LED_PIN[Led];

 GPIO_Init.Mode = GPIO_MODE_OUTPUT_PP; 

 GPIO_Init.Pull = GPIO_PULLUP;

--------------------------------------

 GPIO_Init.Pin = BUTTON_PIN[Button];

 GPIO_Init.Pull = GPIO_PULLUP;

 GPIO_Init.Speed = GPIO_SPEED_FREQ_HIGH;

if (ButtonMode == BUTTON_MODE_GPIO)

 {

/* Configure Button pin as input */

 GPIO_Init.Mode = GPIO_MODE_INPUT;

But I will check internally about the UI why is reset state and not in GPIO_Input or GPIO_Output

I will get back to you asap.
