hello.

have you check this source somehow?

you can check it in modelsim( you can download it from Altera web site)

or QuartusII can compile it.

I have found some errors.

1.write_data

it can't be a register. it is an input-bus.

2.syntax

the line "else HEX7 = 7'b1000000"

you need semicolon.

this is just a syntax error.

3. logical error.

you don't have output.

a module which has no output doesn't make sense.

those are my advice as far as I found.
