For reference, this code works even if the arduino IDE was never opened. It is for ROS but doesn't use rosserial, which I have found to be unreliable in the past.
The only time this code breaks is...

lol! I don't know I've always used Teensies.

The code I'm using is:
#include <ros/ros.h>
#include <std_msgs/String.h>
#include <serial/serial.h>
#include <thread>
#include <chrono>

I didn't uninstall modemmanager so this might be the issue. I'll try uninstalling it.

I have a Teensy 3.6. I can upload sketches (for example the 'Hello World' sketch in examples) from my Ubuntu laptop to the Teensy. The serial output can then be read on my windows 10 laptop after I...

This is the rosserial package: http://wiki.ros.org/rosserial

I can't remember specifically, it just didn't work with Arduino IDE 1.8.7. According to forums some people have got versions 1.8.5 and 1.8.4 to work with ros. I got rosserial to work with arduino IDE...

I've succeeded in uninstalling and reinstalling it. I just needed to delete the arduino folders like you said.

However, this hasn't solved the issue. I can't compile any sketches on it. (they work...

Hi,

I installed Arduino IDE 1.6.13 and Teensyduino 1.32 on my Raspberry Pi 3. (It has to be those versions for ROS to work on it).

I get 'error compiling for board Teensy 3.2 / 3.1'

I'd...

Thank you for your suggestions everyone, it seems that this:

was the issue! After trying a few things it just worked. Now it works with or without pull up resistors. Its this mpu:...

Hi,

I received my Teensy 3.2 the other day and haven't done anything other than 'Hello world' on it so apologies if I've missed something really obvious. I'm trying to connect it with an mpu9250...
