Greetings,
Its been ages since I've done any real math and it's come to haunt me. I was going to make an LED matrix lets say for one character I'd have 5x7 or 8x8 (or whatever), this will be matrix in a 10x2 (for words). The problem I'm having is I can't for the life of me recall how to put this into a formula to quickly determine the spacing. For example, maybe I want them all 3cm apart, that is no problem takes a bit of time but I can come up with an answer, but what if I wanted the maximum allotment to be in a 100cm x 200cm or maybe I might be given the stipulation of having them only be from 0-0.5" apart. IIRC from school I think this was called maximizing the area, if you can point me out to what I should be looking for I'd greatly appreciate it. I also need it to be proportional, since these are to display text I don't want them to come out uneven or wonky. I started with something Like:
X = number of LEDs in the matrix for x direction
WL = width of the LED
S = spacing between LED's
Xmat = # of matrixes in the X direction
Xmax = maximum X lenghth
Smat = spacing between matrix 'characters'
X(WL+S) * Xmat + Smat = Xmax
I believe this works for only ONE direction though, I'd like to plug this in for Y leds but also have a ratio so that letters aren't too skewed, this is where I get lost.
I don't expect this to be solved but maybe even talking me through it a different way might help or a link to some free math with the concept (I'm not afraid to read and relearn). Thanks.
