k230 human body detection

k230 and MSPM0 communication

1. Experimental Prerequisites

This tutorial uses the MSPMG3507 development board, and the corresponding routine path is [14.export\MSPM0-K230\09_k230_person_detect].

K230 needs to run the [14.export\CanmvIDE-K230\09.person_detection.py] program to start the experiment. It is recommended to download it as an offline program.

Things you need:

Windows computer MSPMG3507 development board K230 visual module (including TF card with image burned in) Two type-C data cables Connection cable

2. Experimental wiring
