I started working with the STM32F4xx and I was wondering if the ADC does a calibration automatically. When I was working with the STM32F10xx you had to manually trigger the ADC calibration. Looking at the STM32F4xx reference manual there is not a clear answer if the chip does the ADC calibration automatically. The STM32F4xx reference manual also talks about a t STAB, stabilization time after turning on the ADC. Does anybody know that time is? It's not defined in the reference manual.
