Paul__B: Honestly do not know, haven't used it!
then how do you program this chip ?!! give me an example please online all they use is the LedControl library which here on this website too !
Paul__B: Oh come on!
Why? Well, the logic is inside the chip, you see. That's what we are doing here, using software.
but why not ! i mean we know the connection and how they work, it lets the proper DIG opens so instead we can connect the DIG to a logic gate that will give 0 out from 1 in it's simple
Paul__B: If there is not an available library, you have to make an array with the character font, and use the array to translate. For example the character "0" might be B0111110 - every segment from A to F active, not G or DP. This would mimic the built-in character generator but with segments and digits swapped, you actually have to have a temporary array to hold either the data digits to be displayed, or - probably simpler - their corresponding character patterns. You then read corresponding bits of each byte in the array into each register in the MAX7219 so that the first register contains all the bits for segments A, then next all the segments B and so on.
i don't understand :/ if you see my codes up top you will notice how it works, same as the LCD library some how there is no array no nothing, all are in the library all i have to do is know how to use the function provided
