Communication RS232 and parallell port
Posted on 1998-04-05
Temperaturcontrolling of an oven with PC, to look at floating liquid crystals! You shall be able to control the temperatur of an oven with an temperatur sensor (features a duty-cycle modulated square-wave output voltage with linear response to temperatures in the -45 degreas C to +130 degreas C) wich gives out pulses with voltage 0-5 and an powersupply with serial-communication (RS232). The temperatursensor is connected to the parallellport. A regulator program shall be implemented in C++ code. How can the regulatorprogram communicate with the parallellport and RS232?
