Progamming help with FSBus dll

[sgaert]

try that!!! Completly new Idea from a friend and me.

static int ADF1RelDataIn;
static int ADF1RelDataSave;
static int ADF1RelDataDif;

static int ADF1RelNeedlegoto;
static int ADF1RelNeedleSave;
static int ADF1RelNeedleDif;

static int ADF1RelNeedleDeg = 65536;
float ADF1RelNeedleMulti;
static int ADF1RelNeedleStep = 1150;

case FS_ADF1RELATIVEBEARING:
				printf("Data in: %d\n",val);
				ADF1RelNeedleMulti = ADF1RelNeedleDeg/ADF1RelNeedleStep;
				if (ADF1RelDataSave < ADF1RelDataIn)
				{
				ADF1RelDataDif = ADF1RelDataIn - ADF1RelDataSave;
				if (ADF1RelDataDif > ADF1RelNeedleDeg/2)
					ADF1RelDataDif = ADF1RelDataDif - ADF1RelNeedleDeg;
				}
				else
				{
				ADF1RelDataDif = (ADF1RelDataSave - ADF1RelDataIn) * -1;
				if (ADF1RelDataDif > ADF1RelNeedleDeg/2)
					ADF1RelDataDif = ADF1RelNeedleDeg - ADF1RelDataDif;
				}
				ADF1RelNeedleDif = ADF1RelDataDif / ADF1RelNeedleMulti;
				ADF1RelNeedlegoto = ADF1RelNeedleSave + ADF1RelNeedleDif;
				FsbusWriteFmtVar(29,80,ADF1RelNeedlegoto);	
				ADF1RelNeedleSave = ADF1RelNeedlegoto;
				ADF1RelDataSave = ADF1RelDataIn;
break;

Fantastic Stefan, I will give it a try this evening when I get home from work.

Thanks

Hi Stefan,

I have had a chance to try the new code, I am getting no needle movement at all.

Using the printf function, the Data In is reading exactly the same the the ADF1RelNeedlegoto.

So the data is going from -32 odd thousand to + 32 od thousand.

Here's a copy and paste:
running ...Data in: -32366
ADF1RelNeedlegoto: -32366
ADF1RelNeedleDif: -32366
press any key to exit ...

Any thoughts?

Thanks
David

Oh, I'm also getting this error message:

warning C4244: '=' : conversion from 'int' to 'float',

for these lines:

ADF1RelNeedleMulti = ADF1RelNeedleDeg/ADF1RelNeedleStep;

ADF1RelNeedleDif = ADF1RelDataDif / ADF1RelNeedleMulti;

Oh, I'm also getting this error message:

warning C4244: '=' : conversion from 'int' to 'float',

for these lines:

ADF1RelNeedleMulti = ADF1RelNeedleDeg/ADF1RelNeedleStep;

ADF1RelNeedleDif = ADF1RelDataDif / ADF1RelNeedleMulti;

That is not an error only warning, for me at the moment it isn´t interessting.
But look to a tutorial about Type Casting / Explicit conversion.

running ...Data in: -32366
ADF1RelNeedlegoto: -32366
ADF1RelNeedleDif: -32366
press any key to exit ...

That is not possible, show your print funktions.

Did you fly the aircraft and how run the needle?

Stefan

[RobiD]

Sorry, I did mean warning.

Here is the code copied and pasted :

static int ADF1RelDataIn;
static int ADF1RelDataSave;
static int ADF1RelDataDif;
static int ADF1RelNeedlegoto;
static int ADF1RelNeedleSave;
static int ADF1RelNeedleDif;
static int ADF1RelNeedleDeg = 65536;
float ADF1RelNeedleMulti;
//static int ADF1RelNeedleStep = 1150;
static int ADF1RelNeedleStep = 1400;

case FS_ADF1RELATIVEBEARING:
					printf("Data in: %d\n",val);
					ADF1RelNeedleMulti = ADF1RelNeedleDeg/ADF1RelNeedleStep;
					if (ADF1RelDataSave < ADF1RelDataIn)
					{
						ADF1RelDataDif = ADF1RelDataIn - ADF1RelDataSave;
						if (ADF1RelDataDif > ADF1RelNeedleDeg/2)
							ADF1RelDataDif = ADF1RelDataDif - ADF1RelNeedleDeg;
					}
					else
					{
						ADF1RelDataDif = (ADF1RelDataSave - ADF1RelDataIn) * -1;
						if (ADF1RelDataDif > ADF1RelNeedleDeg/2)
							ADF1RelDataDif = ADF1RelNeedleDeg - ADF1RelDataDif;
					}
					ADF1RelNeedleDif = ADF1RelDataDif / ADF1RelNeedleMulti;
					ADF1RelNeedlegoto = ADF1RelNeedleSave + ADF1RelNeedleDif;
					FsbusWriteFmtVar(29,80,ADF1RelNeedlegoto);
					printf("ADF1RelNeedlegoto: %d\n",val);
					ADF1RelNeedleSave = ADF1RelNeedlegoto;
					ADF1RelDataSave = ADF1RelDataIn;
					printf("ADF1RelNeedleDif: %d\n",val);
					break;

OMG!!!!

First how turn the needle if you fly?

Second learn the printf function thet is wrong what you do.

[RobiD]

Needle does not move at all.

Opps, I see the error of my ways

Have corrected printf function and I'll try it again and report back.

David

[RobiD]

Ok, these are the outputs:


Data in: -10972
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0
Data in: -10903
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0
Data in: -10844
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0
Data in: -10906
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0
Data in: -10868
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0
Data in: -10834
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0
Data in: -10950
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0
Data in: -10956
ADF1RelNeedlegoto: 0
ADF1RelNeedleDif: 0


Just so I'm accurate, this is how I have the printf:

printf("ADF1RelNeedlegoto: %d\n",ADF1RelNeedlegoto);

[sgaert]

Ok.
Fly for a positive Data in val.
and gereate a printf for ADF1RelDataDif.

[sgaert]

Next try.

static int ADF1RelDataIn;
static int ADF1RelDataSave;
static int ADF1RelDataDif;
static int ADF1RelNeedlegoto;
static int ADF1RelNeedleSave;
static int ADF1RelNeedleDif;
static int ADF1RelNeedleDeg = 65536;
float ADF1RelNeedleMulti;
//static int ADF1RelNeedleStep = 1150;
static int ADF1RelNeedleStep = 1400;

case FS_ADF1RELATIVEBEARING:
					printf("Data in: %d\n",val);
					ADF1RelNeedleMulti = ADF1RelNeedleDeg/ADF1RelNeedleStep;
					
					ADF1RelDataDif = ADF1RelDataIn - ADF1RelDataSave;
					
					if ( ADF1RelDataDif > ADF1RelNeedleDeg/2)
						ADF1RelDataDif = ADF1RelNeedleDeg-ADF1RelDataDif;
					else if (ADF1RelDataDif < (ADF1RelNeedleDeg/2 * -1))
						ADF1RelDataDif = ADF1RelNeedleDeg+ADF1RelDataDif;

					printf("ADF1RelDataDif: %d\n",ADF1RelDataDif);
					ADF1RelNeedleDif = ADF1RelDataDif / ADF1RelNeedleMulti;
					ADF1RelNeedlegoto = ADF1RelNeedleSave + ADF1RelNeedleDif;
					FsbusWriteFmtVar(29,80,ADF1RelNeedlegoto);
					printf("ADF1RelNeedlegoto: %d\n",ADF1RelNeedlegoto);
					ADF1RelNeedleSave = ADF1RelNeedlegoto;
					ADF1RelDataSave = ADF1RelDataIn;
					printf("ADF1RelNeedleDif: %d\n",ADF1RelNeedleDif);
					
					break;

please fly 1x 360 left and 1x 360 right and report the datalog.
