what is the best port i can use, USB or RS-232 ?
Quotewhat is the best port i can use, USB or RS-232 ?USB doesn't require any additional hardware. That should count for something.What kind of sensor are you trying to interface with? Pulses per second implies that it is a digital sensor. Sending 0 or 1 to the PC 250 times per second hardly makes sense.What is the PC to do with this data?
Programming with the RS-232 port is easier than an USB port?
