How to calibrate the ADC of a STM32F7?

I am currently using a STM32F767ZI. As the function "HAL_ADCEx_Calibration_Start" is not possible for a STM32F7, is there any other funtion or method (e.g. calibrating manually) for an ADC calibration to increase its accurancy?Thanks for any help.

Resolved! Want (software) reset of CPU (STM32F051) in response to hard fault interrupt but can't compile NVIC_SystemReset() - "implicit declaration..."

I'm exploring STM32F051 using STM32CUBE IDE without use of HAL or lower level support routines (i.e., upon entry at reset vector, manually configure peripheral registers and go - so far so good I wish to cause a reset from within hard fault handler (...
