Any enthusiastic EPL programmers out there?

[Infacta]

If there is anybody out there who is up to date with EPL programming would it be possible for you to have a brief look at the code I have included with this message as I am having some problems with it. The code is very basic and the problem will more than likely be immediatly apparent to experienced EPL programmers (possibly some parts of it are out of date). I am having trouble interfacing some buttons (hardware) to my EPL code and I have just included the relevant sections of code. It should be noted that I have already got my displays and leds working but the buttons are proving a problem. I know that the buttons are working because when I go to 'EpicInfo' in the EpiCenter environment I can see the ticks in the correct positions when I press the buttons however I cannot get the corresponding EPL code to do anything. Also could you tell me the best way of generating events in flight simulator using hardwired buttons -> 'nqw commands'?

Thanks in Advance

If there is anybody out there who is up to date with EPL programming

Try also http://www.avsim.com/bluesideup/ which specialises in EPIC stuff. My EPL is not only rusty, it relates to the old ISA EPIC world, not the new fangled syntax used now.

Good luck!

With recent EPICenter releases, you should be using the new form of button procedure assignment.

your epl-file should look like this:

void FirstDevice.YAWD.On (void) {

ctrlhit(D);

MCP.Row0.NAV_LED = on;

}

This way you can avoid the definemodule statement. Also note the new way of defining outputs.

Good luck!

Yeah thanks sorry about the delay replying was away for a while -> I have upgraded to the most recent EPIC version and upgraded my code as well which seems to have solved the problem.
