Thanks Pete - you have answered my basic question. There is obviously something wrong!
I tried to send a post with more information with an included JPEG, but it failed 'cause the JPEG was still to big. I will try a bit more compression in a while.
The information was that it is a modern PC ie a 1.8 Ghz 256Mbyte RAM, running alone,
no network no other programs other than FS2002/FSUIPC and the compiled EXE servo control programme.
Now that I know it should be faster, I will experiment with the various i/o sections. As I mentioned, I am using the HELLO program as the structure for my program and I have alreadY reduced the Timer period to 5 milliseconds and checked for any delays in the code. I am sTill using the display box from HELLO to check display/check connection.
I have noticed that the cycle time of FS itself may be a factor. The turn/bank coordinator looks as though it may only be refreshed by FS
at that rate. Maybe I chose the wrong dial/variable for my test (offset 037C). Apart from using the FS sliders to minimise what FS has to do
is there anything else I should do? As you said, there must be something really odd happening.
I must say, that apart from the slow cycle time, the FSUIPC software is working very well with no errors and the supplied sample programmes are invaluable.
Best regards,
Ian.
