[simpits-tech] milestones...

Yesterday marked another milestone in the development of the cockpit 
interface software I'm working on.

The software now not only takes input data from the BI hardware, but now 
also works with DirectX input devices.

Here's an example of the Lua code I use to handle the step-up and 
step-down of the COMM radios in FlightGear:

-- Testing FREQ_UP and FREQ_DOWN buttons
Com1Freq = CIM:GetStringValue("COM1_FRQ")
if CIM:GetInput("FREQ_DOWN") == true then
    repeat
      -- do nothing
    until CIM:GetInput("FREQ_DOWN") == false
    Com1Freq = Com1Freq - .250
    CIM:SetStringValue("COM1_FRQ", Com1Freq)
    CIM:SetValue(0, "FREQ_DOWN - " .. Com1Freq)
    return
end

if CIM:GetInput("FREQ_UP") == true then
    repeat
      -- do nothing
    until CIM:GetInput("FREQ_UP") == false

    Com1Freq = Com1Freq + .250
    CIM:SetStringValue("COM1_FRQ", Com1Freq)
    CIM:SetValue(0, "FREQ_UP - " .. Com1Freq)
    return
end

This basically checks to see if there has been an input on one of the 
buttons matching the "FREQ_UP" or "FREQ_DOWN" definitions.  If it sees 
that one has been pressed, it will sit there and wait until the button is 
released and then perform the needed action.

The wait-until-release is done because the script executes in its own 
thread and would cause a flurry of up or down frequency changes if it 
didn't wait for the button to be released.

Full end-to-end communication with FlightGear (http://www.flightgear.org) 
is now fully operational.  This means that you can pull data from 
FlightGear as well as change things within FlightGear.

I've done some initial work with MSFS 10 using version 4 of Peter Dowson's 
FSUIPC.  I need to spend more time on that this week to get it nailed down 
the rest of the way.  I'll also take a peek at what it will take to 
integrate SimConnect.
