Took awhile to write new post :) I have did this multiplexing and it works. I'll just put photo and schematics here, everything about multiplexing you can read in previous post.
And a hex compiled program (for simulation purpose I set low flickering frequency, the real one have higher), which scrolls through alphabet and digits on leds.
Next todo is scrolling through words and phrases and maybe some info on font drawings. Stay tuned.
