I'm using "STM32L452CC".

PA11 pin in connected to battery level checking part.

But I can check only ADC1_EXTI11,

and I'm using ADC1_IN5,6,7,8,9(PA0,1,2,3,4 pins) DMA_cirgular.

So, for battery level checking, I wanna use "GPIO_Analog".

But i cannot search any example or any function in stm32l4xx_hal_gpio.c, stm32l4xx_hal_adc.c or in hal library.

How can I get the value of gpio_analog pin?
