Hi DynamoBen,

Ok, but how make it in picbasic pro?
I send three variables with eight bits (byte) each, for another pic.
I don't know how to implement it.
Thanks, Daniel

What you are asking is very general, I'm not sure what would work best for your application. You will have to choose a method that works for you. The best I can do is suggest things that might work, you will have to sort through the details or each option. If you have specific questions about a specific method we should be able to help you out.

Have you searched the forums and read through other discussions on this topic? If so that should give you a start. Below are some threads that might help spark some ideas.
