To anyone who is wondering why am i so silent the last days its because i am full into the reversing an rewriting state of the LCD pricetags
The reversed code looks very good already and an ArduinoC version in the making
Hard part, only when everything is ready it will work
First update pushed to the display :)
That was a long night
Next step is to sniff and update and look into the protocol to make a custom Access Point
