How to make program to mux 16 to 4, and demux 4 to 16?
(no subject) (by MGP)
Like a 74154 TTL IC ? there is always only 1 output active, is that what you want?
Attached in samplesV2.zip you can see the beginning how to decode that, look at binairy-in.ld and binairy-out.ld files, you can build a program on that.

thank you.
if possible check the files and tell me if they are correct or if there is another way to do it. 16 inputs to 5 outputs 4 inputs for 12 outputs.

You didn't answer my question!
Keep in mind that you should never make more than 1 of the 16 inputs high, that is a 16 to 4 encoder. Think about whether that's what you want to make.

yes, that's right 1 at a time

Ok then your programs are well made, maybe the program codificator16x5.LD can be shorter by using the #PORTA, #PORTB or the instruction BINTOBCD instruction, but for that you need to know the controller used in advance.
But it will work as it is.
