For a start, I think you will want to call the sleep function in the Execute loop otherwise the CPU will go to 100%, and having a tpHigher priority, this will likely semi-hang your main program thread.

AtoDThread := TAcquisitionThread.Create(FALSE); AtoDThread.Priority := tpHigher; AtoDThread.Resume; // now run the thread Inside the AtoDThread the Execute DLPortIO := TDLPortIO.Create(nil); DLPortIO.DriverPath := 'c:\DMT\Plotter'; // This is where we've installed it. AtoDState := RESET_HARDWARE_STATE; while not Terminated do ; // Do nothing but ideally suspend somehow while leaving the timer running. What I'd like to do is just have the Execute thread do nothing else other than let the timer fire which then gathers the data and fills appropriate variables etc. If I suspend the thread I believe it will also suspend the timer won't it? What's a better way to block the execute part of the thread while leaving the timer active?
