The stadard ADC in STM32 is SAR at 12 bit but there ara also some STM32 that iclude also a SIGMA-DELTA ADC at 16 bit. 0 as well as IEEE 802. Because the STM32F407 ADC has no internal FIFO it can overrun very easily, hence its interrupt must be at the highest priority and be permitted to preempt other interrupts.
the ADC. Its purpose is to help ADC users to understand the advanced modes offered in STM32 microcontrollers, and to quick start development. This document is divided into three sections: • Section 1: Comparison between ADC F1 family and F3 family describes a brief comparison between the two ADCs of STM32 F1 and F3 family.

I'm attempting to get two ADC's to simultaneously sample on a STM32H743. However, I cannot seem to read the values from ADC2 correctly. From my understanding, when running in dual simultaneous mode, the data from the two ADC conversions are written to the buffer as a 32 bit word.
