Jun 04, 2015 · In the next step you have to configure your processor. For a STM32-F4 you have to choose Cortex-M4 core, while for a STM32-F1 you have to choose Cortex-M3. The Clock, Flash size and RAM parameters depends on your Nucleo MCU. For Nucleo-F401RE you can use the same values shown in the following picture. Set the other options as shown below. -

These error values are specified in the ADC characteristics section of STM32 microcontroller datasheets. Different accuracy error types are specified for the STM32 ADC. For easy reference, accuracy errors are expressed as multiples of 1 LSB. The resolution in terms of voltage depends on the reference voltage. -
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.

Sep 21, 2018 · Nice question. I didn’t actually illustrate how this x16 times faster sampling rate works or contributes to considering a specific bit to be 1 or 0. However, i beleive that it’s illustrated much better in my STM32 UART Tutorial. You can also google this subject to get an idea how reading a uart bit 16 times is useful. -

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.

There’s also word(h , l) to combine two bytes, or highByte() and lowByte() to divide 16-bit variables into 8-bit two pieces.
