FSX control of Servos for motion Platform

[SamSpiteri]

I intend to build a 2DOF flight Simulator Platform using initally two small servo motors. I am using Link2FS software by Jim to extract the Data from Flight Simulator X and intend to use Arduino Uno to drive two small servo's via a dedicated USB port.

Does anyone have a sketch to do this.

It would help if you added more detail. How does the program output the data to the serial port and what is the format of the data?

Thanks for the time. I intend to use link2fs software to output the data to the serial port. This enables me to select which output I need for the 2dof i.e. pitch and roll. I some how did this and can see the chart provide different outputs as FSX flies.

I am advised that the Arduino Uno can read this and with the correct sketch can drive two small servos.

I copied this sketch (below) from "Jim page NZ" but when I try to upload I receive a "char" to "const char" error message.

Not being a software person I am stumped.

Thanks in anticipation of any help.

#include <Servo.h>

String pitch,pitchold;

void setup()
{
myservopitch.attach(9);
Serial.begin(115200);
}

void loop()
{
if(Serial.available()>0){
j1= Serial.read();
if(j1=='A'){
delay(5);
pitch =char(Serial.read());
pitch+=char(Serial.read());
pitch+=char(Serial.read());
pitch+=char(Serial.read());
pitch+=char(Serial.read());
pitch+=char(Serial.read());
if(pitch!=pitchhold){
char carray[9];
pitch.toCharArray(carray,sizeof(carray));
int n=ato(carray);
n=map(n,-90,90,0,179);
myservopitch.write(n);
pitchold=pitch;
}
}

Sam,,
You are trying to use a PDE that was written in Arduino IDE version 0022 but it wont compile in the later IDE's.
Most of my stuff has been updated so it works on version 0022 right thru to the latest version 1.1 so download a later PDE and see how you go.
All the newer stuff is available here ,,

Good luck and have fun ,,, Jim
