Writing Values in "free" FSUIPC Offsets

[xxallrounderxx]

Hi there!

 

I wanted to create a lua file for writing values from Airbus X Extended in the free Offsets 66C0-66FF, for further output to my "Arcaze Board" via "Arcaze FSUIPC Connector". I tried, but failed :(

a = 0
while a < 255 do
b = 0
c = 0
d = 0
e = 0


--IAS
b = ipc.readLvar("L:AB_AP_Speed_Select")
--HDG
c = ipc.readLvar("L:AB_AP_HDG_Select")
--ALT
d = ipc.readLvar("L:AB_AP_ALT_Select")
--VS
e = ipc.readLvar("L:AB_AP_VS_Select2")



--Writing Speed
ipc.writeUB(0x66C0,b)

--Writing Heading
ipc.writeUB(0x66C1,c)

--Writing Altitude
ipc.writeUB(0x66C2,d)

--Writing Vertical Speed
ipc.writeUB(0x66C3,e)

ipc.sleep(800)
end

The code should write the values of Speed, Heading, Altitude, VS in the Offsets. I put the Script in the Modules Folder of FSX. Any ideas why it down't work?

 

 

 

Thanks,

 

Philipp

I notice you are only using 1 byte for each. Is that enough? That range of an unsigned byte is only 0-255.

How are you running it? Just puting it in the folder won't run it.

Hi Pete!

So, if it wouldn't be enough a range of 0-255 for heading example, what do i have to write instead of "ipc.writeUB"?

For Vertical Speed I will need something bigger for negative values...

I don't know how to run the lua file after starting fsuipc/fsx. How do I?

Thanks

Oh dear. It is in the documentation!

 

UB = Unsigned Byte.

UW = Unsigned Word

 

Look at the FAQ subforum. There is a guide there to bits and bytes and numbers.

 

Byte = 8 bits, 0-255 unsigned or -128 to +127 signed

Word = 16 bits (0-65535 unsigned or -32768 to + 32767 signed.

 

Et cetera.

 

Don't forget also the offsets are at 1 byte intervals (normal memory addressing. So for a 2-byte spacing you need 66C0, 66C2, 66C4 etc. You list 1 byte spacing.

You really have not read any of the documentation, have you? :-(

 

Run it by assigning to a button or keypress, then using that button or keypress, OR

Run it by naming it ipcReady.lua, OR

Run it by executing it like a macro in an [Auto] section in the INI file.

 

Please please please use some of the documentation. It was hard work writing it. i don't want to have to do it all again here.
