I have a Diecimila and serial communication using ASCII is working fine. But string manipulation isn't really what the Arduino should be doing so I was wondering if there is a tutorial somewhere showing binary serial communication? I.e. with int and float values in binary format, not ASCII.
Which binary number representations does the Arduino use? I think the program (written in C++) on the PC side could construct the binary representation before sending it over the serial port so that the Arduino did not have to do any reformatting.
Has this been done?
