  • Can you give some details on how to wire the chip. Would DIG-0 on the chip goto SEG-A on the display. And SEG-A on the chip to DIG-0 on the display?
    Since the chip is common cathode and the LED is common anode.
    Thanks
    Update: I did get it to work with a common anode LED display. Here's are the connections.
    (MAX7219-LED)
    DP-CA
    D0-DP
    D1-Seg-A
    D2-Seg-B
    D3-Seg-C
    D4-Seg-D
    D5-Seg-E
    D6-Seg-F
    D7-Seg-G
    Second LED would use be:
    (MAX7219-LED)
    SEG-A-CA
    D0-DP
    D1-Seg-A
    D2-Seg-B
    D3-Seg-C
    D4-Seg-D
    D5-Seg-E
    D6-Seg-F
    D7-Seg-G
    and so on !!

No public wish lists :(
