How to input ASCII values coming from serial. E.g if 8-bit ASCII code '80' of alphabet P, or 8-bit ASCII code '49' of digit 1 is recieved at serial port, how do I input this ASCII.
"What is a debugger and how is it used?" Sorry, I should probably have said simulator rather than debugger. Run your code in the simulator, you will be able to view the value of variables to see what is happening. If you don't know what the simulator is then I'm afraid you are going to have to resort to reading the manuals.
