DIY Arduino LED news ticker / Digispark LED banner with MAX7219 / DIY LED scrolling message display

[ENABLE CAPTIONS!] In the video I am getting absolute MAX out of Digispark / ATTINY85 by constructing LED scrolling display with following features :
maximum 500 characters text for scrolling
support reverse mode ( right to left reading - Middle East guys) for Arabic, Aramaic, Azeri, Divehi, Fula, Hebrew, Kurdish, N'ko, Persian, Rohingya, Syriac and Urdu
text stored in non-volatile EEPROM memory and once disconnected from the PC it will replay it continously. Up tp 10000+ uploads possible (more than for FLASH memory)
second option to store text in RAM ( for constantly changing messages .,.. like news display mode - uploaded from the PC / Raspberry )
test uploaded over USB ( DigiCDC library ) or over Serial Port ( SoftSerial library + Serial-to-USB converter)
maximum 12 LED 8x8 MAX7219 displays in USB version and up to 30 LED 8x8 displays in SerialPort version (DigiCDC USB library is taking more RAM...)
the cheapest Arduino used - Digispark for 2USD
works under all operating systems - Windows 10 , Windows 7 , any Linux , MacOS... , even Android phone with OTG cable and FTDI232 converter may be used to upload the text to display

Method for enabling DigiCDC USB driver under Windows 10 : https://github.com/protaskin/LowCDC-W...



BTW. The ATTINY85 chip gets really hot when processing my program (it has a lot to do...), do not touch it :-)
