There are no instructions for calibrating ADC in STM32F407

after googling around a while and reading the STM32 manual section for the ADC, i am frustrated about the lack of such a section in the manual.


So how IS the ADC in the STM32F4 actually calibrated??




I found this thread: 


STM32 how to use VREF to Calculate the actual VDDA value 


However, if i do so on my STM32F407VGT (Discovery Board), i dont have a VREFINT_CAL value.


Should i just measure VREFINT on Channel 17 of the ADC and assume this is exactly 1.25 V?
