LED 8x32 (green) matrix module driven by MAX7219

MAX7219 is 7seg LED display driver. But LEDs does have to be placed in 7seg style - so MAX7219 can drive 8x8 LED matrix. And MAX7219 chips can be joined in chains. Thus this 8x32 LED matrix - built from 4 modules placed side by side.

But - since MAX7219 chips can be joined even in longer strips - You can attach next modules to get even longer display.

From all MAX7219 powered 8x32 LED modules this green one LEDs are not so bright like red or blue ones…

Libraries:

• MD_MAX72XX (chip interfae): MD_MAX72XX on Github
• MD_Parola (text, align, etc): MD_Parola

Using this libraries set MD_MAX72XX::FC16_HW as hardware type. In case display is wrong (letters are reversed on each submodule) try other variants: MD_MAX72XX::PAROLA_HW, MD_MAX72XX::GENERIC_HW or MD_MAX72XX::ICSTATION_HW.

On Starter Kit we have post with example how to use this module.
