Need help with codes (continuity cable tester with lcd 16x2 i2C)

Btw, as you can see (photo) my results display 000000000000 (12 digits).
Is it possible to show on display:
123456789101112 for each wire?
Like, RJ45 tester (without shift register)

Example:
123456
12X564

Thanks


Note:
0 = open
1 = close
X = short
