Hello, I am beginner with STM32. I have STM32F3 and I use DAC. I need to know value of Vref+, but I can´t find this number in datasheet, ref.manual or pin Vref+ on discovery kit. Do you know where can I find this number or how I can meassure it?  Thank you very much for hints.

You could look at the board schematic, VREF should either have it's own pin or use VDDA, would suggest you check the voltages and regulators on the board. Based on other designs this will either be 3V or 3V3
