Rosserial problem with std_msgs on Arduino
Hello,
I am trying to connect ROS with Arduino using a simple subscriber and publisher program to blink a LED on an Arduino but I am getting an error when including the stdmsgs/Int8.h library on arduino. It says that there is no such file or directory but I have already followed all the steps on the ROS tutorial and the library is already in my roslib inside arduino.
I have also tried including the Rosserial library from the arduino IDE but I still get the same error.
Does anyone know how to fix this or if I am doing something wrong?
Pablo.
Arduino code:
include
include
ros::NodeHandle nh;
void messageCb(const stdmsgs::Int8& togglemsg){ if(toggle_msg.data==4){ digitalWrite(13, HIGH-digitalRead(13)); } }
ros::Subscriber
void setup() { pinMode(13, OUTPUT); nh.intNode() nh.subscribe(sub);
}
void loop() { nh.spinOnce(); delay(500);
}
Arduino error:
est:2:10: fatal error: stgmsgs/Int8.h: No such file or directory #include <stgmsgs/Int8.h> ^~~~~~~~~~~~~~~~~ compilation terminated. exit status 1 stg_msgs/Int8.h: No such file or directory

@cmnewton Yeah sorry, the format got a bit weird when I uploaded it, surprisingly I tried running the blink example from ros_lib instead of my own code and it worked so now it's fine. Thanks for the help anyway!

Can you add the code as preformatted text? this is hard to read. It's also missing the # before include. And why do you have ' =""' ' at the end of your include? And did you look at the tutorial: http://wiki.ros.org/rosserial_arduino/Tutorials/Blink ?
