Wiring MAX7219

[hog_driver111th]

Hey guys,

 

I'm building up my hornet pit (though I wish I had the room for a tandem tomcat) and I came across the MAX7219. I bought one, which will be arriving later, since I had read that you can use the LEDs separately for around the cockpit. I won't need it for the upper caution panels as I have a PCB for those, but would like to use it around the cockpit for all the other indicators and lights.

 

I suck at just looking at the diagrams and need more pictures. Does anyone know the best way to wire up regular 5mm LEDs to the MAX7219 for use around the cockpit? Things like Landing Gear handle, Gear/Flaps, Hook, Lower Caution Panel, anything else... ? This is the matrix that I bought. I was thinking I could desolder the array on top and wire up the LEDs but not sure how.

Thanks!

Hi hog_driver111th,

 

Take a look at the schematic done by TigersharkBS;

It is for tha caution panel for the A-10C but should give you an idea of how to wire the LED as individual instead of 7-segments as described in the datasheet;

I am pretty sure I followed this when setting up mine but I seem to recall it's the same layout as TigersharkBS

The board though looks similar to yours
