Serial Communication Interface Design Based on Lab VIEW and VC Mix Programming

This article proposed one serial port communication program method, which the DLL functions called by Lab VIEW. In the method the DLL functions are compiled with VC++, and call the DLL function in LabVIEW. The serial port communication is realized in LabVIEW environment by the mix programming between Lab View and VC++. The hybrid method is used in temperature control on injection mould machine, which used serial port for temperature data communication.
