I have a Max7219 that I'm trying to use to individually control around 24 Leds. I'm a little unsure how I should group the Leds and determine the scan-limit and Rset values since it's not a standard 8x8 matrix. For 24 Leds would it be best to do 3 (SEG) rows of 8 (Digits)? Or something like 5 Rows of 5 Digits?
I may be reading the Datasheet wrong but the Scan-limit seems to allow you to block scanning columns of digits so in the 3x8 example would that mean I set the scan-limit to 0xX2? There seems to also be a warning in the Datasheet about using (0xX2) but I can't quite figure out what it means.
Thanks for any guidance.
