My adc is measuring -3,3 to 3,3 that 16 bit but I wanna build it as 0 3,3 V how can I configure it in this form?

None of the STM32 support ADC of +/- 3.3V
Perhaps you be more specific, and detail how this is relevant to the forum

What board is this? A custom one? Share a circuit diagram, illustrate what you're trying to do.
The IC is not designed to take -3.3V on any of the input pins
I'd imagine doing so would probably cause damage to the IC or the pin in question.

STM32H743ZIT6 . I am trying to measure 0 3.3 V from ADC and make it as 16 bit.
When I connect jumpers to pins that shows in photo and When I apply 0 V I read 32768 approx...
I wanna get this measurement between 0 and 3.3 Volt. Thankss

STM32H743ZIT6 is a CHIP, not a BOARD
What BOARD is this on, and what's the CIRCUIT?
Why are you connecting -3.3V, this is way outside the absolute maximums? Damagingly
so.
Make sure you have a common ground between the STM32 and whatever else you're connecting too.
Make sure VSSA is this same Ground, and VDDA is 3.3V
DON'T go above/below this limits
