OK, here ya go. The data I posted below may have to be inverted depending on how the Velleman outputs a logic high/low, but the basic principle is there. I assume a bit set to 1 turns the output transistor off (Makes the output high) in the example data below:
E1
F1
D2
F2
B3
F3
74
F4
Doh! I only have 2 of the 4511s. But I do have an ICM7212 4 digit decoder driver, any good?
