I use setDigit() to write a character on a 7 seg. How to delete that character, so nothing is displayed? Not to write 0, but to print nothing?
use the void setDigit(int addr, int digit, byte value, boolean dp); function with value=22 (aka ' ') see the LedControl.h source code file for more explications.
void setDigit(int addr, int digit, byte value, boolean dp);
value=22
