I have a task of interfacing with a an I2C device (a data transmission protocol from Philips) using a PC. According to information I found on the Internet, an 12C device could be interfaced with a PC by connecting the device to PC's parallel port where in between the port and device is an interface circuit. I have trouble finding a driver (like a Windows DLL) to communicate with the device thru parallel port. I wonder if it is possible to use LabView's InPort and OutPort VI to start off the communication.
