hi- I am trying to use the serial port for input and output. I first tried to use the interupts but the Keil software's monitor overwrites our interupt. We've switched to scanning for data. I have seen references on this forum to using scanf. I have tried this but I can never type in the serial window for the simulator or in a hypertermal window when running on the board itself. How have people been able to use serial input? Thanks -John UC Berkeley Solar Car Team
