This utility converts text input to code used for the frames entries for the 8x12 LED Matrix of the Uno R4 WiFi.
The text will scroll from right to left, eight LEDs high and twelve wide.
Enter text below, eight lines, maximum 5,000 characters wide.
Use X for LEDs to be set on, space for off.
To continue scrolling the text until the display is blank, include twelve spaces at the end.
You can also enter just 8 lines by 12 columns to fill a single screen and use just the last entry (or the complete output to have it scroll into place).
