Advice on LedControl library

As I said, if you daisy-chain two 4-digit modules you'll just have to ignore digits 4-7. To display "1234.5678" you'd have to:

LedControl lc=LedControl(12,11,10,2);  // Two modules daisy-chained

void setup() {
   lc.setScanLimit(0, 4);   // Use only 4 digits on the first module
   lc.setScanLimit(1, 4);   // Use only 4 digits on the second module

   lc.setDigit(0, 0, 1, false);
   lc.setDigit(0, 1, 2, false);
   lc.setDigit(0, 2, 3, false);
   lc.setDigit(0, 3, 4, true);  // Decimal point
   lc.setDigit(1, 0, 5, false);
   lc.setDigit(1, 1, 6, false);
   lc.setDigit(1, 2, 7, false);
   lc.setDigit(1, 3, 8, false);
}
