LED Matrix scroller spacing

Hello,

I was playing around with this code a little:
http://musicdiver.com/wordpress/2013/01/arduino-scrolling-text-on-5x7-led/

And after putting capitol A to Z in there, I noticed there is no spacing between the characters.
How easy would it be to put a let's say 1 row of spacing between each character.

It would make reading messages much easier I think.

Easiest way is to add in a column for each character definition.

From this

#define H { \
{1, 0, 0, 0, 1}, \
{1, 0, 0, 0, 1}, \
{1, 0, 0, 0, 1}, \
{1, 1, 1, 1, 1}, \
{1, 0, 0, 0, 1}, \
{1, 0, 0, 0, 1}, \
{1, 0, 0, 0, 1} \
}

to this

#define H { \
{1, 0, 0, 0, 1, 0}, \
{1, 0, 0, 0, 1, 0}, \
{1, 0, 0, 0, 1, 0}, \
{1, 1, 1, 1, 1, 0}, \
{1, 0, 0, 0, 1, 0}, \
{1, 0, 0, 0, 1, 0}, \
{1, 0, 0, 0, 1, 0} \
}

You will probably need to adjust other elements in the code to process the extra column.

It works.....now why didn't I think of that....... :wink:

Guess sometimes the answer is right under your nose.
Thanks for this quick and dirty workaround.

Perhaps because Marco is the expert in this matter. :sunglasses:

Seriously!

Marco's answer was great!
I've put upper and lower case letters in my code now and also numbers 0 to 9.
I'll upload a video and the updated code later today.

This is the result of a little altering:
