No.

They are general-purpose microcontrollers - you would have to develop your own software & hardware.

You would need some sort of sensor, and software to interpret the sensor's output.

Common sensors include

  • Wheel rotation sensors - give pulses at a rate proportional to speed
  • GPS - usually give speed (or even velocity) directly
  • Radar
  • Ultrasonic
  • optical

You would need to give more information for any specific help.

How to write your question to maximize your chances to find a solution

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

+ You can use TouchGFX library to display the speed tachometer in the GUI.
