If you have the following 7-segment displays:
2-digit 3-digit 4-digit
is it possible to control the 2-digit, 3-digit and the first 3 digits of the 4-digit 7-segment display from a single MAx7219, and then control the remaining digit of the 4-digit display from another MAx7219? Or do you have to ensure you control all digits from the same MAX7219?
If I can do that, then I can use 10 MAX7219's for my project instead of 14.
