Hello,
I'm analyzing a labview programma that enables a at89c51cc03 microcontroller to communicate with a labview programm running on a pc trouhg serial communication (uart based). I believe my predecessor used some sort of event based communication. Does anny of you happen to have experience with this type of programming and got tips on how to ensure a robust communication? I am programming in C51
this piece of code is not very interesting. did you not complain about timing problems? if that is still the case, please show us how the serial port is initialized, how the serial ISR looks like etc. also post other ISRs of higher/equal priority that might serve as a bottleneck in your system.
