hi hero,
That 'binary to to 7seg converter' link is misleading.
The 7447 is a BCD to 7 segment converter, there used to be a binary to hex converter many years ago, not seen one for ages.

This question from the OP comes around often, IIUC he wants to convert a binary number into to displayed decimal 2 digits.
So binary 0x0f would be displayed as decimal 1 5.

Yes, you're right, I misunderstood the question.
