Hi guys,
I bought one of these 4 digit 7 segment displays a while back and now I have a use for it in a project - however I cannot figure out what the pinout is whatsoever?
I haven't powered it up since I got it, partly because I don't want to burn it out by wiring it up incorrectly, and partly because I just can't figure it out?
I understand how a single 7 segment display works and have used 4026's to control them before, however the pinout doesn't make sense, and neither does the datasheet as it has nothing but electrical charaacteristics?
(From Sparkfun's website)
Note: The pinout in the datasheet is incorrect. This is the correct pin-out:
1: Digit 1 16: B
2: Digit 2 15: G
3: D 14: A
4: Colon Anode 13: C
5: E 12: Colon Cathode
6: Digit 3 11: F
7: Decimal Point 10:Apostrophe Anode
8: Digit 4 9: Apostrophe Cathode
However, I don't know which pin is pin 1 as there is no indication?
Could I possibly end up burning this out if I wire it up incorrectly when trying to figure it out, and do you have any suggestions on how toi protect the display when experimenting?
Many Thanks,
Morrolan
