TMF8829 Shield Board Web GUI

A browser-only viewer for the TMF8829 on the TMF8829_EVM_EB_SHIELD Evaluation kit. The page talks directly to the board over USB using the Web Serial API — no Python backend and no Arduino firmware needed. Connect the Shield EVM board via USB and open

https://ams-osram.github.io/tmf8829/tmf8829_web_gui.html

in a browser that supports WebSerial (Chrome, Edge or another Chromium based browser).

The same file runs on Android using WebUSB as well.

Using TMF8829 Web GUI on Linux

The Web GUI generally works on Linux, tested on Ubuntu 26.04 / Chromium 153.0, but streaming is much slower than on Windows or Android, especially when enabling histograms.

# Install chromium
sudo apt update
sudo apt install chromium
# if chromium is installed as snap, enable snap access to usb
sudo snap connect chromium:raw-usb
# connect EVM and check if USB is visible
lsusb
# this should show a device with "ams AG Core FW EVM-H5"

Open https://ams-osram.github.io/tmf8829/tmf8829_web_gui.html in Chromium and "Connect". If you get "Failed to open serial port" use:

# check if any other program has the port open - below should not show any programs
lsof /dev/ttyACM0
# add the current user to group dialout for access to serial port ttyACM0
sudo usermod -aG dialout "$USER"
# need to restart Linux or re-login to make group changes effective

TMF8829 JSON Logfile viewer and CSV exporter
