program for gauges, Servos.

Hi all, i am french and i dont speak german and my english is bad.

Je me fait un simulateur genre FREX et je voudrais créer un compteur avec : vitesse, RPM, T° Huile, Pression Turbo, Essence.

J'ai 6 servos et une carte USB
http://www.opencockpits.com/catalog/tarjeta-servo-p-42.html?cPath=21_32

Mais je ne sais pas ou trouver les informations dans le jeu.
Avez vous un plugin, ou un code source d'un plugin existant svp ?

merci / thanks

Il n'ya support par la carte de open cockpits jusqu'ici. Mais si tu prêtes la carte pour quelques jours a Sirnoname, il peut fair la carte marcher avec X-Sim. Surement il te la envoye en retour quand il a terminé l'implémentation.

Mais tu pouvais controller les servos aussi avec autres cartes qui sont supporté dans X-Sim dèja.
Pour example:
- http://www.pololu.com/catalog/product/207/pictures (8 servos)
- ou avec un gameport carte vieille rc-servo-with-soundcard-t1006.html (8 servos)

Salut
Christian

salut et merci pour les liens, je les avais deja lue.
je veux passer par l'USB.

Pour la programmation, ca va je sais le faire.

c'est pour récupérer les informations du jeu ou je n'y arrive pas.

il faudrait que je connaisse le fichier ou je pourrais trouver ses informations.

Merci encore.
A+

Hello
i try to speak english.

I would like create car's instruments.

i got 6 servos http://cgi.ebay.fr/6-MICRO-SERVOS-E...3286.c0.m14&_trkparms=66:2|65:1|39:1|240:1318

and i bougth a card USB for servos.
this one : http://www.opencockpits.com/catalog/tarjeta-servo-p-42.html?cPath=21_32

i would a plugin or a program for GTR2.
how do you do to take the information of GTR2 ?

thanks for the source code, i'm gonna try to use it. but it's gonna be hard.
if you got other idea, im interested.

Bye

The plugin sourcecode is an example of an software interface between an external I/O-card and X-Sim software.
You will get game via the X-Sim software into your I/O card.

Lend Sirnoname your OpenCockpit interface for a few days, and he will most likely be able to write a plugin for it.

regards

thanks thanks thanks you very much. :clap:

The tutorial is very good. :clap:

thanks again :yes:

hi,
i dont understand how i can find the adress memory.

i got $gtr2$ and 180 byte = 22,5 octet

but after, i dont know how to use it.

i use the program windev and i try to use the fonction ReadProcessMemory but i don't know parameters.

if i have the source code of mmfvisualizer, i could read how you read in memory.
for exemple, in mmfvisualizer, we put $gtr2$ and 180,
the button open MMF, what does he do ? with $gtr2$ and 180 ?

I am sorry for my english and my questions, it's not very clear

thanks.

Hi and Thanks.

So, i have to use the CreateFileMappingA fonction instead of ReadProcessMemory ?

if i find CreateFileMappingA parameters, will i find what i need ? RPM, speed.... ?

ok so for me :

my code :

AppelDLL32(kernel32, CreateFileMappingA ,hFile,lpAttributes,flProtect,dwMaximumSizeHigh,dwMaximumSizeLow,lpName)

i use parameters et the result will be what i need.

that's it ?

Hello.
Thank you for the code but I do not understand.
I try, I try, but I do not.

I succeed to retrieve a value from a memory address but I can not find the address memory of GTR2 values.

the code that I do not understand :

I got a bug : The fonction OpenFileMapping not found in the Kernel32 DLL

i think it's because of FILE_MAP_READ when i use OpenFileMappingA
i got an other message : The passage of the parameter 1 has caused an error.

good night and thanks again for your help.

:hi:

program language is WINDEV. http://www.windev.com/

its a very easy program. you can test the version 10 free.
its here : http://www.windev.com/windev/WD-Express.htm

Th program fonctions are for me in french with easy fonctions. for exemple :
info(Je m'appel Sanka)

in the help pf program, a search fonctions :
transferts()
extraitChaine()
AppelDll32()
API()

all fonctions, program and help are in english too.
I learned with this software has my job, I did not learn C.
Bye

@sankaman77

Why dont you simply try to make your interface compatible to X-Sim? If you get it to accept X-Sim data, then it will work with every game that X-Sim supports.

hi all.

Code:

AppelDLL32(kernel32, CreateFileMappingA , hFile, &lpFileMappigAttributes, flProtect, dwMaximumSizeHigh, dwMaximumSizeLow, &lpName)

for me with parameters =

Code:

nAdresseBloc est un entier = AppelDLL32(kernel32, CreateFileMappingA ,0xFFFFFFFF, Null, 4, 0, 180, $gtr2$)

nAdresseBloc = 368, i dont understand

how does it work?

Sirnoname posted a plugin example some posts before:

download/file.php?id=1549

Open the file to see the sourcecode, and modify it to your needs (to make it compatible with your interface).

If you are not able to read C++ programming language, it may be not possible for you to work that out.

regards

:hi: Hi

OK so my code begins by :

mmfhandle est un entier = AppelDLL32(Kernel32, OpenFileMappingA,0xF001F,True,$gtr2$)
nTest est un entier = AppelDLL32(kernel32, MapViewOfFile , mmfhandle,FILE_MAP_WRITE,0,0,0)
mmfhandle = 328 if Gtr2 runnig and 0 if is not (It's Ok :happy: :yes: )
nTest = 24510464 it's the memory address ??? if yes, .... :yippiee:

ok but, adress memory of what ?
how I find the values of gtr2 with nTest ?
i use the fonction ChaineRécupère and she give me (nothing)

And : if I understand, I never use the function CreateFileMapping ????

Bye

:hi: Hi

:yippiee: :yippiee: :yippiee: i succeeded !!!!!!

my code :

Code:

mmfhandle = AppelDLL32(Kernel32, OpenFileMappingA,0xF001F,True,$gtr2$)
AdresseMémoireDépart = AppelDLL32(kernel32, MapViewOfFile , mmfhandle,FILE_MAP_WRITE,0,0,0)

ChaîneDest est une chaîne fixe de 180
LongueurTransfert est un entier = 180
Transfert(&ChaîneDest, AdresseMémoireDépart, LongueurTransfert)
Libellé1  = RPM =  + Asc(ChaîneDest[[24 A 27]])
Libellé2  = Carburnant =  +Asc(ChaîneDest[[36 A 39]])
Libellé3  = T° Eau =  +Asc(ChaîneDest[[44 A 47]])
Libellé4  = T° Huile =  +Asc(ChaîneDest[[48 A 51]])
Libellé5  = Vitesse =  +Asc(ChaîneDest[[56A 59]])
Libellé6  = Nbr Tour =  +Val(Asc(ChaîneDest[[64 A 67]])+1)
Libellé7  = Meilleur Tour =  +Asc(ChaîneDest[[68 A 71]])
Libellé8  = Dernier Tour =  +Asc(ChaîneDest[[72 A 75]])
Libellé9  = Temps =  +Asc(ChaîneDest[[76 A 79]])
Libellé10 = Rapport =  +Asc(ChaîneDest[[89 A 91]])

but, but i got problem, again,
1 - sometimes, AdresseMémoireDépart = 0 and i got a big error. and sometime, it works.
2 - only gear work in continue, not other, i dont understand, it's the same code.
3 - how free memory atthe end of sequence, because after 2 minutes, my program use 300Mo of RAM.
4 - How convert int to float ?

I'm so happy. thanks :clap:

Hi
1 - sometimes, AdresseMémoireDépart = 0 and i got a big error. and sometime, it works.
I found, its Kernel32 and not kernel32

2 - only gear work in continue, not other, i dont understand, it's the same code.
?????? I dont understand :no:

3 - how free memory at the end of sequence, because after 2 minutes, my program use 300Mo of RAM.
For that, i am looking for

4 - How convert int to float ?
I have wrong ? that is what i understood with mmfReader.exe

UnmapViewOfFile(inputmmf);
Yes, I use it. :yes:

Hi, it's my last problem.

mmfhandle = AppelDLL32(Kernel32, OpenFileMappingA,0xF001F,True,$gtr2$)
AdresseMémoireDépart = AppelDLL32(Kernel32, MapViewOfFile , mmfhandle,FILE_MAP_WRITE,0,0,0)
AdresseMémoireDépart = AdresseMémoireDépart+1
LIB_Connect = AdresseMémoireDépart
LIB_Connect1= mmfhandle
ChaîneDest est une chaîne fixe de 180
LongueurTransfert est un entier = 180
Transfert(&ChaîneDest, AdresseMémoireDépart, LongueurTransfert)
Libellé1 = Asc(ChaîneDest[[24]]) // = 59 or C
Libellé2 = Asc(ChaîneDest[[25]]) // = 63 or ?
Libellé3 = Asc(ChaîneDest[[26]]) // = 20 or Cube
Libellé4 = Asc(ChaîneDest[[27]]) // = 68 or D
AppelDLL32(Kernel32, UnmapViewOfFile,mmfhandle)

And I want 592.99 (Calculated Float values, 4 byte)
I dont understand how to do.
Can you help me again ???

ok thanks.

it's time to say a thing. :thbup:
a big, big, big thanks for the help you gave me. It has me helped enormously. :yes: :thbup:
you have taken time for me and I thank you very much.
if one day, you will come to Paris, send me a mail and i offer you a drink at home. :

Bye bye and thanks again :highfive: :hi:
