Pretty stuck with this; done loads of Googling but can't figure it out! I'm trying to write a decimal point in the lower right-hand corner of the 7-seg display, which will in turn differentiate between AM or PM. Using writeDigitNum works on it's own, but I'm using matrix.print and want to illuminate the DP with this.
One way I can think of; where I've put the '???' possibly there is some form of placeholder that can go here to tell it not to change the existing variable...?
Code: Select all
matrix.print(hour() * 100 + minute());
matrix.writeDigitNum(4, ???, true);
matrix.writeDisplay();
Any ideas? Thanks!
