Arduino and X-Sim

Ok, now I got it working like I wanted at this point of my career. Only thing which was wrong was test-tablet configuration, where I put max 255 and min 0. In Math setup graph this configuration shows only positive values, and I though it was right. But then I once again read tutorials and there were said that middlepoint is 127 in output... So I conffed test-tablet to max/min 2000 and output 8bit one characer. Then I read that char to unsigned int in Arduino, and it works like I wanted...
Thanks all! :

Nice one !

Please keep us posted with your project :beta:

Hi I am using a Arduino UNO but I cant display RPM.
In Force Profiler it read the correct value but I don't know how to send it to Arduino.

I sent the speed value correctly but RPM don't work :?

Hello,
May i know what i need to put into datapacket part of USO to send the data to arduino uno? ~255~~9~~a01~/S~a01~E ?
Regarding the coding part, how to split the Serial.read() to control 2 servos?
myservo.attach(9,10);
Serial.read(x,y)
Thank you...

How do you setup the Arduino Card in Force Profiler?

You set up Profiler in arduino..

You have to program arduino to receive data in a certain way, and you have to send this specific data from profiler.

oh
hmm has anybody a ready Sketch for programming Arduino Duemillenove?
For receiving Data?
Im totally new in Arduino programming

If you are new to arduino, wouldn't it be a good idea to learn the basics before you jump into programming and interfacing?

There are many tutorials and sample programs around.

hmm
means this i have to program evry move from profiler and evry step to Arduino? Or is it only 1 routine to get the data from xsim?
if its to much to programming Than i will buy a new K8055.

I've used the HammerHead code to programmed the uno...
S~a01~E for uso...

the motor keep spinning if stop and it will shaking if i start the profiler...
i've tried S~a01~~90~(motor spins fast)/S~a01~~1~(motor spins slow)

i need to know what is the correct format for uso... :
thank you.

any news here with Arduino?

Hi, i have tested arduino + dsmhb with success.
check it out on video gallery: tube/index.php?mode=item&id=Pmrl5-f-CXM

very nice.
can you send me the picture of the profiler setup and the sketch for the arduino please?

Hi,
the sketch below, it is not a P.I.D sketch yet, is only a servo-control that drives the motor to value mapped from USO (0-255) 8bit resolution. the sketch has a better perform running in 9600bps, because the Read_Lateral (function) uses delay to wait strings from serial... this code is based on http://roamingdrone.wordpress.com/2008/ ... ntiometer/

Maybe we can change this to a PID control with this: http://www.arduino.cc/playground/Code/PIDLibrary
See you

thank you very much.

great work..

Hi Menix.. have you got it working?

Dear juniou,

i'm interesting with your project using arduiono + dsmhb, please send us the layout for connecting? and also the complete coding.

thank you very much

definal,
you can define your own layout,
you just need to declare the variables according to you cable connections... like:

#define MOTOR_EN_PIN 6
#define MOTOR_RT_PIN 2
#define MOTOR_LT_PIN 3
#define MOTOR_EN_PIN2 9
#define MOTOR_RT_PIN2 4
#define MOTOR_LT_PIN2 5


I sugest you to understand how Dsmhb from Thanos works...
and check some codes on www.arduino.cc Digital\Analog pins examples...
If you have some basics of how it works... you can define your own cable pinout between arduino pins and dsmhb pins

The above code, is the complete sketch, and the cable layout is on the code ;-)

fun video with sketch working..
