# AI-on-the-edge-device
|
|
|
|
This is an example of Artificial Intelligence (AI) calculations on a very cheap hardware.
|
|
|
|
### Details on **function**, **installation** and **configuration** can be found on the **[Wiki Page](https://github.com/jomjol/AI-on-the-edge-device/wiki)**

### 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!

|
|
|
|
##### 6.6.1 Image Processing in Memory - (2021-04-05)
|
|
|
|
* NEW 6.6.1: failed SD card initialization indicated by fast blinking LED at startup
|
|
* Improved SD-card handling (increase compatibility with more type of cards)
|
|
|
|
##### 6.5.0 Image Processing in Memory - (2021-03-25)
|
|
|
|
* Upgrade digital CNN to v8.2.0 (added new type of digits)
|
|
* Supporting alignment structures in ROI definition
|
|
* Bug fixing: definition of hostname in `config.ini`
|
|
|
|
##### 6.4.0 Image Processing in Memory - (2021-03-20)
|
|
|
|
* Additional alignment marks for settings the ROIs (analog and digit)
|
|
* Upgrade analog CNN to v7.0.0 (added new type of pointer)
|
|
|
|
##### 6.3.1 Image Processing in Memory - (2021-03-16)
|
|
|
|
* NEW: 6.3.1: bug fixing in initial edit reference image and `config.ini` (Spelling error in `InitialRotate`)
|
|
* Initial setup mode: bug fixing, error correction
|
|
* Bug-fixing
|
|
|
|
##### 6.2.2 Image Processing in Memory - (2021-03-10)
|
|
|
|
* NEW 6.2.2: bug fixing
|
|
* NEW 6.2.1: Changed brightness and contrast to default if not enabled (resolves to bright images)
|
|
* Determination of fixed illumination settings during startup - speed up of 5s in each run
|
|
* Update digital CNN to v8.1.1 (additional digital images trained)
|
|
* Extended error message in MQTT error message
|
|
|
|
|
|
* Image brightness is now adjustable
|
|
|
|
|
|
* Bug fixing: minor topics
|
|
|
|
|
|
##### 6.1.0 Image Processing in Memory - (2021-01-20)
|
|
|
|
* Disabling of analog / digital counters in configuration
|
|
* Improved Alignment Algorithm (`AlignmentAlgo` = `Default`, `Accurate` , `Fast`)
|
|
* Analog counters: `ExtendedResolution` (last digit is extended by sub comma value of CNN)
|
|
* `config.ini`: additional parameter `hostname` (additional to wlan.ini)
|
|
* Switching of GPIO12/13 via http-interface: `/GPIO?GPIO=12&Status=high/low`
|
|
* Bug fixing: html configuration page, wlan password ("=" now possible)
|
|
|
|
##### 6.0.0 Image Processing in Memory - (2021-01-02)
|
|
|
|
* **Major change**: image processing fully in memory - no need of SD card buffer anymore
|
|
|
|
* Need to limit camera resolution to VGA (due to memory limits)
|
|
* MQTT: Last Will Testament (LWT) implemented: "connection lost" in case of connection lost to `TopicError`
|
|
* Disabled `CheckDigitIncreaseConsistency` in default configuration - must now be explicit enabled if needed
|
|
* Update digital CNN to v7.2.1 (additional digital images trained)
|
|
* Setting of arbitrary time server in `config.ini`
|
|
* Option for fixed IP-, DNS-Settings in `wlan.ini`
|
|
* Increased stability (internal image and camera handling)
|
|
* Bug fixing: edit digits, handling PreValue, html-bugs
