Is it a correct way adding "ch=0;" inside a case to get only a value from the selected case?That will cause the corresponding function to get called once when the command was received, and not run again until the command was sent again. If I understood your original post correctly, that's not what you wanted.
Hi PeterH!
What I wrote above is very useful to me to get the function returns only one value instead of multiple values (that's what I need to obtain from "Pres()" function).
Another time thank you very very much for you help! Really useful to me!
