I want to scan string from keyboard and display on LCd ,but when scanning the next string ,the buffer for saving pre_string will be changed to the value in scanning buffer,and the display also will be changed. so i want a solution for scanning string from keyboard .can you give me some flowchart or code for example. best regards, nantiangumo
I'm sorry, but I don't understand your question. Could you try to explain the problem more clearly? One thought: do you really intend your switch case statements to fall through?
