Hi, I have two computers (Win XP) and must get one of this computer to send a small amount of measurement data (4k) each 20ms to the other computer. In the receiving computer there is running a real-time process in a loop (20ms, real computing time: 5ms), which needs the actual measurement data in time. There is no possibility to make both jobs on one computer. Anybody have an idea for a proper way to implement the communication? For the hardware, I think to take Firewire or a parallel cable. But how to implement the software without breaking the control process while waiting for new data. Open e network drive and write each 20ms a new file? Take a pipe? Thanks for your suggestions.
