Call HAL lib inside Call back

Hello,

Is it Ok to read GPIO pins inside a timer call back as follow:

void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef* htim)

{

if (htim == &htim2 ) //15 ms

{

BT1 = HAL_GPIO_ReadPin(GPIOx, Pin_x);

BT2 = HAL_GPIO_ReadPin(GPIOx, Pin_x);

BT3 = HAL_GPIO_ReadPin(GPIOx, Pin_x);

...

}

}

Thank you
