I am going to use 4x TPIC6B595 and 4x 7 segment display with common anode. Below You Can find vendor site of this display. https://sklep.avt.pl/wyswietlacz-led-2-30-57mm-zielony-wa.html
Here is my diagram: diagram
I want to display 4 digit number. Will it work? Or do i need also MIC2981 chip to supply more current?
I didn't use shift registers like TPIC before. Could You show me a basic code to make display show 4 digit number?
Thanks in advance.

1In this case you don't need the MIC2981 to switch the anodes because the anodes can be continuously powered. In your previous attempt, which used a single shift register and multiplexing, it was necessary to switch the anodes. Check that 9 volts is enough before proceeding too far. 12volts is probably better with that display.
