## 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!
