Question

Electronics

Which microcontroller to choose for the development of a device, the main and defining functionality of which will be the ability to connect via USB and configuration settings, in which direction to dig? What to choose as the basis of the project.
A little more detailed: there is a code, it should be based on the config that is uploaded to the MK / memory / somewhere, the config is edited / updated through the utility on the PC
Which MK to choose for further study and prototyping?

Answer 1

What does the iron itself do? How many resources do you need for this? Store the config on a flash drive will be able to almost any mk. In general, take proteus, build a simulation, play around with different microns.

Answer 2

I will suggest stm32.
modern arm-architecture, knowledge of it will not hurt anywhere.
inexpensive all-inclusive dev-boards.

Answer 3

As an option - MSP430F5529 and a scarf based on it.
