Guys,
I spent some time on the weekend with Peter Dawson's Manual, and a lot of Trial and error.
I know most of you at one time went looking for this information, and sometimes are afraid of the direction the conversation can go.
Well here is the start of a Tutorial Thread that should help us all out.
Please if you are an expert in
FSUIPC and Offsets, this thread is not needed for you, this is just so that maybe I can help some people not go through what I went through this weekend again.
I noticed that in PM systems there are so far two types of offsets being used. I am only 32 Buttons into this, so there may be more added here soon.
ie. Engine Start switch..
Offset X0000 Byte = 0 //--- Engine GND
Offset X0000 Byte = 1 //--- Engine off
Offset X0000 Byte = 2 //--- Engine CONT
Offset X0000 Byte = 3 //--- Engine AIR/FLT
Using Leo Bodnar's cards, or any joystick button input we program this like below.
FSUIPC Buttons/Switches menu
- Press the button
- select function
Offset SET Byte
- Type in the 4 digit offset number
- Parim ON = X //-- X = 0,1,2,3 the function when the button is depressed
- select Function
Offset SET Byte
- Type in the 4 digit offset number
- Parim OFF = X //-- X = 0,1,2,3 the function when the button is released
For instance On my Rotary switch I have the following when you turn it to the left for start.
- select function
Offset SET Byte
- Parim ON = 0
- select Function
Offset SET Byte
- Parim OFF = 1
Turnig to the right I have.
- select function
Offset SET Byte
- Parim ON = 2
- select Function
Offset SET Byte
- Parim OFF = 1
Very easy eh?
Ok well here is where I got confused..
the 737 has 4 landing
light switches. The Light offset has several Bits assigned to it, for instance bit .4 is the far left switch, .3 is another switch .2 is another and so on.
This works similar to above except we are not assigning a value to the bit. we are only setting the bit or clearing it.
FSUIPC Buttons/Switches menu
- Press the button
- select function
Offset SET bits
- Type in the 4 digit offset number
- Parim ON = the Bit number in HEXADECIMAL See Chart Below.
- select function
Offset Clr bits
- Type in the 4 digit offset number
- Parim OFF = the Bit number in HEXADECIMAL See Chart Below.
if you set the Parim OFF to 00, it clears all bits, therefore turning one switch off, appears to turn all switches off belonging to that offset number.
Here is the best way to understand the bits/hex.
Binary Counts Like this. 0 1 2 4 8 16 32 64 128
Hex counts to 16 like this. 0 1 2 3 4 5 6 7 8 9 A B C D E F
Each Hex Number is made up of 4 Binary Numbers. The Below shows the Hex Value for Bit .4
Bit Numbers: 7 6 5
4 | 3 2 1 0
Binary 2 groups of 4: 8 4 2 1 | 8 4 2 1
HEX Value 1 0
for Bit .5 it would be
Bit Numbers: 7 6
5 4 | 3 2 1 0
Binary 2 groups of 4: 8 4 2 1 | 8 4 2 1
HEX Value 2 0
for Bit .0 it would be
Bit Numbers: 7 6 5 4 | 3 2 1
0
Binary 2 groups of 4: 8 4 2 1 | 8 4 2 1
HEX Value 0 1
I will add to this further, as I progress, but it really did take me an eternity to figure this information out.
I hope I haven't confused anyone, but Please feel free to ask questions if you have any, and I will try to answer.
