I use stm32f4-discovery board. I am working with the ADCs, and for my prpose I need to set the ADC reference VREF+ at 3.2V. in the reference manual RM0090 it is said that stm32f4 LQFP100 has VREF+ VDDA pin. But the discovery board doesn't have any of those. So how can I set the reference voltage to my requirement  in the Discovery board.

With regards,
