Text to code converter for output to the LED matrix via the ArduinoLED Matrix library

Official Hardware Classic UNO R4 WiFi
1

Here's a web converter that will will accept a text input and output the code necessary for use with the ArduinoLEDMatrix library. Just create eight lines of text, with X where you want an LED lit up and space for those to be off. The utility will create output with the three 4-byte lines of hex (plus the delay line) for each frame of the 96 LEDs which when used with the ArduinoLEDMatrix (Arduino_LED_Matrix.h) library on an Uno R4 WiFi, it will scroll the output from right to left.

Doesn't work, arrays always contain 0 (except delay value).

Perhaps I should have specified to use capital X's? I'll make it allow either.

I'm confused as to where the text is written in relation to the X's and spaces you talk about. Can you give us an example of what we type?

Try this, and set the delay to 100 or so:

X    X   XXXXXX   X        X         XXXX
X    X   X        X        X        X    X
X    X   X        X        X        X    X
XXXXXX   XXXXX    X        X        X    X
X    X   X        X        X        X    X
X    X   X        X        X        X    X
X    X   X        X        X        X    X
X    X   XXXXXX   XXXXXX   XXXXXX    XXXX

It's not taking char strings and knocking out the columns (my idea of "text to code").
