Important!!!
Delphi 7 doesn't know TByte type as Adata in IdUDPServer1UDPRead
so i changed it to TStream, and it's work but compiler sometimes throw you this message:





Just click NO button

I hope that it will be helpful for someone
#2 - Dygear
Cool, and from a Demo Racer! Very nice sir, sounds like a good candidate for the nicest, most helpful Demo Racer.
#3 - Eclipse2000
and wat would i use this for?
#4 - NotAnIllusion
Quote from Eclipse2000 :and wat would i use this for?

It looks like it displays OutGauge data (car, engine telemetry, read the docs on OutGauge) in a form. If you have any use for such info to use externally (out of LFS) it's a good place to start working if you're coding in Delphi.

In other words, unless you're a Delphi coder, you don't have much use for this. It's essentially a "Hello World" tutorial for accessing/using OutGauge.

Could be wrong though, never had a look at Delphi before
#5 - Radekteam
It's only a tutorial code. I have in plans to display those data on HD 44780 lcd ,but now i've put it here for anyone who need help with outgauge in Delphi. It may be usefull Thanks for comments
#6 - Nadeo4441
Its very nice, but i have a question, how to control shiftlight & others?
#7 - ReVoX
uh, nice for the first outgage
#8 - W1ldPort75
Nice prog m8 , keep up the good work .

Quote from Nadeo4441 :Its very nice, but i have a question, how to control shiftlight & others?

Shift lights can be controled by reading RPM. Others? What others? Could you precise your question?

nice, didn't know people still used delphi

Check my sig to see what's possible with outgauge

I'm working now on LCD SMARTIE PLUGIN for LFS. It's almost finished. In few days (maybe Saturday) i will release it.
#13 - Nadeo4441
i mean
#define OG_SHIFTLIGHT 1...
#14 - Radekteam
Oh yea, in declared packet you have variable called Flags - here are summed the values of all OG_ - you just must know how to decode it - if you want i can tell you how to decode it but it's complicated to explain in one post
#15 - Nadeo4441
Well, i have no idea how to decode it..
#16 - kingfag
Decoding them is easy.


#define OG_SHIFTLIGHT 1
#define OG_FULLBEAM 2
#define OG_HANDBRAKE 4
#define OG_PITSPEED 8
#define OG_TC 16
#define OG_HEADLIGHTS 32
#define OG_SIGNAL_L 64
#define OG_SIGNAL_R 128
#define OG_REDLINE 256
#define OG_OILWARN 512
#define OG_1 1024
#define OG_2 2048
#define OG_3 4096
#define OG_4 8192
#define OG_KM 16384
#define OG_BAR 32768

You see the number behind the flag? If you bitwise AND it to the Flags variable, you can check if a flag is on or off.

basically you do this:

if Flags AND 256 = NOT 0 //og_redline is on

I never really used Delphi, but it should be something like that.
#17 - Radekteam
Yes, kingfag you've got right. It should be working in delphi too.
#18 - Nadeo4441
But it doesnt work
#19 - kingfag
Quote from Nadeo4441 :But it doesnt work

That's a bit like going to a garage and saying "my car doesn't work", without giving a clue what doesn't work.

The proper syntax would be

if (Flags AND 4) <> 0 then
writeln('handbrake is on');
else
writeln('handbrake is not on');

#20 - Nadeo4441
Yes you are right , im idiot
I have forgot to put it to ()
#21 - shaun463
Nice, keep it up!

Sorry MY BAD English.. I From Argentina..

I'm using Delphi 7 Personal. You should try to install the newest indy 10 components. This maybe the reason why your delphi throws you this error
#23 - SilverFox_cz
my modified version can you make it with analog gauge ?

Hey, on what device do you run it ?

Quote from SilverFox_cz :my modified version can you make it with analog gauge ?

I think I can, but I must find component for analog gauges or write it myself( and it's not easy). BTW Nice device
