Gents, I am looking for a way to control a warning light panel that essentially is 48 LED's arranged in 12 rows and four columns behind some plastic translucent covers with test on them.
The DSC Bios script will be used with it, and the output that DCS Bios reads is as follows for an Arduino to light a particular LED
DcsBios::LED clA1(0x10d4, 0x0001, PIN);
So, I believe that a MAX7219 chip can be used do control this, rather than having to assign 48 Arduino pins to the LED's individually.
I have seen that the MAX7219 can do 8 x 8 matrices, however I don't see any schematics for the 12 x 4. Also, I would like to understand how you can assign the value extracted by DCS Bios to a particular LED in place of the 'PIN'
Any help in understanding the basics is gratefully received!
