K230 and microbit communication

1. Experimental Prerequisites

This tutorial uses microbit, and the corresponding routine path is [14.export\microbit-K230\7.Microbit_k230_eye_gaze].

K230 needs to run the [14.export\CanmvIDE-K230\07.eye_gaze.py] program to start the experiment. It is recommended to download it as an offline program.

 

Items needed:

Windows computer, microbit, USB to TTL module, K230 vision module (including TF card with image burned), type-C data cable, connecting cable (Dupont cable), alligator clip, import K230AI library: https://github.com/YahboomTechnology/K230-Module.git

3. Main code explanation

image-20250728185227919

From the code, we can simply configure the serial port and call the relevant serial port and K230 building blocks to obtain data.

  • x0: is the horizontal coordinate of the eye starting point
  • y0: is the vertical coordinate of the eye starting point
  • x1: is the horizontal coordinate of the gaze direction
  • y1: is the vertical coordinate of the gaze direction

 

4.Experimental Phenomenon

  1. After connecting the cables, the k230 visual module runs offline After K230 is connected to Canmv IDE, open the corresponding program, click [Save open script to CanMV board (as main.py)] on the toolbar, and then restart K230.

image-20250429194108060

  1. Find the hex program of this tutorial, right-click the hex program, and upload the hex program of this tutorial to the microbit

image-20250715192327072

  1. The serial port assistant is set to the interface shown in the figure image-2023060600004

    1. When the K230 camera recognizes a face, the serial port assistant will print out the information transmitted from K230 to microbit.
  • x0: is the horizontal coordinate of the eye starting point
  • y0: is the vertical coordinate of the eye starting point
  • x1: is the horizontal coordinate of the gaze direction
  • y1: is the vertical coordinate of the gaze direction
