Topic: 8x32 Matrix Control With MAX7219 (Read 7357 times) previous topic - next topic


2/19: I've just been playing with MAX7219-managed 8x8 LED matrices (4 and 8 module units), using LEDControl.h.

Sourcecode downloadable. Limited "tutorial" to go with it...


As presented, it produces scrolling text. Don't be alarmed if the letters are "the wrong way up"... that happens because different mfgs wire the LEDs differently. It is easily... if tediously... fixed by transforming the character definition matrices.

The software would also do if you only need static text.

It would be more useful if you fixed the link to the code.  Right now the link near the bottom of that page just links back to the same page.  Copying and pasting the info doesn't work either.
