Need help with VHDL!!! =(

Thanks Mazel and James Bonanno for your help.

buf is a signal, you have to use <= to assign it a value. := is used for variable

Thanks! I always get confused with that.

Then, buf is one bit long, you cannot select which bit to use!

I don't really get this. :confused:

PS : your first process is kind of strange...

At reset, you set serial_in_port to '0', then you test if serial_in_port is smaller than '1'. Of course it is!

Is this the behaviour you're waiting for ?

Yea, it is strange lol. I'm kinda new at this. So it's kinda messed up. =s

card_in1 <= X"0000" ;

header1 <= X"A";

t_stamp1 <= '1';

station1 <= X"0";

--- Quote End ---

What does the x mean?

So, I changed all of the types to std_logic and there's an error saying that

"rst" does not agree with its usage as "boolean" type.

. Tried changing all the types to bit and still got the same error. How do I fix this?
