openmotion-pylib 1.4.0

Python library to communicate with STM32 for loading FPGA and camera sensors (OpenMOTION).

Overview

This repository contains the code used to interface with an OpenMotion sensor module and OpenMotion Console. The sensor module runs the code contained in the motion-sensor-fw repository on an STM32H7 processor. The programs here communicates with the modules over a USB serial connection.

A library called omotion is imported in many of the python scripts listed here to aid communication with the Sensor Module.

Getting started

1. Install requirements.txt (pip install -r requirements.txt)
2. Install libusb for your system requires libusb to be installed, for windows install the dll to c:\windows\system32, download the correct dll from github libusb Releases
3. Plug in your aggregator module. Please wait 10 seconds for it to boot up before continuing.
4. Run python multicam_setup.py - this will flash each camera sensor one by one. Alternatively, you may flash just a single camera sensor by usising python flash_camera.py 1 - this will flash just camera 1
5. Run python monitor.py 1 - this will flash the camera with a few parameters (test modes, exposure times, gain settings, etc), start the camera streaming, start the frame sync generating, and then put the cameras into streaming mode. It will then recieve the histogram data for the defined number of seconds then close down. Modify the parameters at the top of this file if you want to adjust the gain, exposure time, etc. Change the number in the command line arguments to change the camera you'd like to interrogate. Cameras are numbered 1-8 and correspond to J1-J8 on the aggregator board.

from repo root rebuild and install

python -m pip install --upgrade build twine python -m build # creates wheel + sdist under dist/ python -m pip install --force-reinstall dist/openmotion_pylib-1.3.3-py3-none-any.whl

quick runtime check (on Windows box with your device bound to WinUSB/libusbK)

python -c "import usb, omotion.usb_backend as ub; print(ub.get_libusb1_backend())"
