How to write software to interface with hardware?

**xLusi0n** · 05-08-2005, 05:29 AM

OK...this question may be way out there, I'm just looking for a general answer...I have a Engine Management System that uses a serial output to connect to my laptop. Using the supplied software (DOS based) it communicates with the EMS and I can do things like change settings, read outputs, etc...

My questions is:

1) Is it possible to write/code my own software to interface with the EMS to display the outputs (i.e. water temper, boost pressure, air intake temp) to a windows GUI-type display? (say to integrate into a program like CentraFuse).

I don't need an instruction manual (not yet anyway), but a brief idea on how one would go about doing this.

Thanks!

yeah its pretty easy, serial comms in delphi isnt hard at all, then its just a matter of prasing strings as they come in.

have you got a log file on what is coming in? send it too me i'll see what i can do.

yeah, it is pretty easy if you can get documentation on what is being sent over the line. A bit harder would be to reverse engineer what is being sent over the line, especially if you the communication is two way.
