While trying to use GPIO inputs as inputs for the ADC, I discovered that the ADC control mode was not programmed correctly in the function HAL_GPIO_Init.

I replaced:

        temp &= ~(GPIO_ASCR_ASC0 << position) ;

        temp |= (((GPIO_Init->Mode & ANALOG_MODE) >> 3) << position);

with

        temp |= GPIO_ASCR_ASC0 << position;

and got it working properly.

If you agree, I suggest you correct this in a future release.

Hi verhelst.bas,

I think that your problem is not really related to a bug in the HAL_GPIO_Init function but it’s in the way that you initialize your GPIO mode structure.

 I guess that you program your structure as below 

 GPIO_InitStruct.Mode = GPIO_MODE_ANALOG ;

 But it has to be: 

 GPIO_InitStruct.Mode = GPIO_MODE_ANALOG_ADC_CONTROL;

Syrine, You're right. I how have successfully ported the Motor Control software from F4xx to L476 and IHM07M1 board.
