Hi forum,

I am searching for an ASM routine with the following capability:

Four pins of a microcontroller are representing the binary input. Each input state (from 0000 to 1111) is supposed to be assigned to one of 16 port pins.

I started writing a routine but it is kind of amateurish and needs an incredible amount of precious memory. As mentioned, I need it in assembly.

Maybe someone has an idea for a short routine or an internet link to look up.

Thanx in advance
