Please .hex file

@Calimaniak87 I've added a link to .hex in the description

Well done, but using a decoder for rows (1-of-4 demux or a decoder made of transistors [4 extra PNP transistors]) could save you 2 pins for output.

Also, it might help with speed because it would need only inc instead of messing with rotating (not sure about this hint - it comes from times of no μCs and no RISC).

[Mrkirill578]

@PolasekPetr Thanks! I've thought of doing it. However, I decided to keep it like this, just for the simplicity.

[Mrkirill578]

@explorerchess2 , Yes, I know that CMOS chips might be unstable with unconnected pins, So I've NOT left them floating, ( pin 10 Vcc , pin 13 GND ).

[explorerchess2]

@Mrkirill578 Ok. I am happy you di dnot take it bad... But if I may add something else, I guess you posted the schematic to give a general idea of the thing right? In your actual proto you probably did not let pin 13 floating right? (neither 10...) :-/

[Mrkirill578]

@explorerchess2 Yes, you are right. I've uploaded a fixed schematic.

Hello. That's good. On small thing: I think the pinout of the '595 in the schematic you are showing on your link is incorrect is it possible? The serial input of the '595 is pin 14 so it cannot be left unconnect on both one. I am reporting this simply in case someone do a copy-and-paste of this and it would not work...

So well crafted!!! Great job! You keep inspiring me, haha.
