Point JeVois towards some ArUco marker and confirm that you see these messages in your serial console.Since DemoArUco sends 2D messages and we selected the Normal format, we expect messages formatted as: N2 id x y w h See Standardized serial messages formatting for more information about standardized message formats.Setpar serstyle Normal to instruct JeVois to send any detections to the serial-over-USB port, and to use the Normal standardized message format. Connect to JeVois using a serial terminal, and issue: setpar serout USB.Start video capture software and select YUYV 640x500 20.0 fps which should launch the DemoArUco machine vision module.In this tutorial, we will write a simple Python program to read and parse the messages sent by JeVois over serial. ![]() Many machine vision modules running on JeVois send messages over serial port (either the hardware 4-pin connector, or the serial-over-USB port) to indicate what they have found (e.g., detected ArUco marker IDs, decoded QR-Code contents, identified TensorFlow objects).
