Hello:
Thanks for the link. I did not know it was done. It is a good idea to do it from the Raspberry Pi, more direct. The problem that Raspberry uses operating system and Arduino or PIC firmware, smaller and does the same.
I was just looking for the data that is on this website. (Thanks to the partner who put the link).
Https://raw.githubusercontent.com/vdudouyt/minipro/master/devices.hIt occupies that information 4.3 MB, it does not fit directly into the Arduino.
What to do?
Use a Micro-SD card for information on each device as shown by the 4.3 MB link.
The tests I have done with Arduino UNO is to embed two photos inside the microcontroller and get it through the serial port to the PC. A very small jpg and other png. Unencrypted and encrypted.
The microcontroller of the TL866 trying to hide is a
PIC18F87J50. As you can see, it occupies 128K. Some of the information is in PC software 6.60 and sends commands to the TL866 to configure the selected device. TL866 has many switched transistors, it also has that data to configure the data. It does not use extra EEPROM on the TL866.

Too bad that TL866 does not release its source code from its 6.60 software.
