Coming next

• Automated update of the neural network file (tflite) to make the learing of additional pictures much easier and automated (GitHub action)
• New "hyprid" neural network for digital numbers --> allowing the detection of intermediate states ("ring between two numbers") as a subdigit

Change log

Known Issues

• slow response of web server during picture analysis
• spontaneous reboots (mostly due to html access during image processing) - self recovery implemented

General remark: Beside the firmware.bin, typically also the content of /html needs to be updated!

Rolling (2022-01-04)

• Reduce ESP32 frequency to 160MHz

Rolling (2022-01-03)

• Update tflite (new source: https://github.com/espressif/tflite-micro-esp-examples)
• Update digital neural network (dig-s1-q-20220102.tflite)
• Increased web-server buffers
• bug fix: compiler compatibility

10.0.2 - Stability Increase (2022-01-01)

• NEW v10.0.2: Corrected JSON error

• Updated compiler toolchain to ESP-IDF 4.3

• Removal of memory leak

• Improved error handling during startup (check PSRAM and camera with remark in logfile)

• MQTT: implemented raw value additionally, removal of regex contrain

• Normalized Parameter MaxRateValue to "change per minute"

• HTML: improved input handling

• Corrected error handling: in case of error the old value, rate, timestamp are not transmitted any more

9.2.0 - External Illumination (2021-12-02)

• Direct JSON access: http://IP-ADRESS/json
• Error message in log file in case camera error during startup

• NEW 9.1.1 bug fix: LED implemenetation
• External LEDs: change control mode (resolve bug with more than 2 LEDs)
• Additional info into log file
• Bug fix: decimal shift, html, log file

9.0.0 - External Illumination (2021-10-23)

• Implementation of external illumination to adjust positioning, brightness and color of the illumination now individually
  • Technical details can be found in the wiki: https://github.com/jomjol/AI-on-the-edge-device/wiki/External-LED
• New housing published for external LEDs and small clearing: https://www.thingiverse.com/thing:5028229

Additional ideas

There are some ideas and feature request, which are not followed currently - mainly due to capacity reasons on side of the developer. They are collected here: FeatureRequest.md
