Upside down and backwards is just the row/column order reversed. The definitive answer is to buzz the rows and columns out using a battery and resistor and then wire to suit. The video you originally posted was very close to perfect. The rows appeared to be fine and only a couple of columns were out. Try doing a sequence of setLed going from column 0 to column 7 and compare to what column lights up you will then find the problem.

There is no such thing as a stupid question but there are a lot of inquisitive idiots.

You mention a little software tweak can fix the effect......


can you check out my code in a thread above and show me maybe where it can fix it please?

What would you learn if I do it?

You need to learn to debug things. Start by writing a program to light up individual LEDs all across the array and see if you get what you expect.

No, I don't answer questions sent in private messages (but I do accept thank-you notes...)
