I have used Proteus design suite for simulating sensors (such as temperature sensor) interfaced to LPC2138. The sensors which were not available in the software, for them I have modelled them as voltage divider circuit with potentiometer. If I were to show mapping/compare the voltage divider results in software simulation and in hardware design, will the results have any dependency on the type of controller as all I am doing is simulating a controlled environment (by changing the R values)? For example if I use Arduino for hardware testing and LPC2138 in Proteus. Would this be correct? Please confirm.
Proteus is highly unreliable in circuit simulation. Sure, you can run your code to check if its working or not but that is the extent of it. Never depend on any simulation results from Proteus. You said that you have modeled sensors as Voltage dividers which is exactly what I am talking about: You can check if changing the voltage has any effect or not and that maybe fine but do not make the mistake of comparing it to your hardware results. There will always be a big error in Proteus results. Trust me, I learned it the hard way.
