I was hoping someone could help me. I have been controlling 2 separate 7-segment displays from a raspberri pi. I purchased a dual seven segment display but it only has 10 pins (not 18 like I would have expected).
Pin Schematic (about half way down) :

How do I display 2 separate digits on this device ?
Pin 10 = Digit 1
Pin 5 = Digit 2
The rest of the pins are for the 7 different segments, and the decimal points.
I tried to bring pin 10 high/pin 5 low, display a digit, then bring pin 10 low/pin 5 high, display second digit. That doesn't work...
