I'm trying to make a publisher in Arduino to send some data to ROS. But I can't do it unless I comment the timer I have on my code. I'm using timer3 but already tried timer1 also.

The problem I get when running "rosrun rosserial_python /dev/ttyACM0" is : "Unable to sync with device"

But when the timer is off it works perfectly.

I'm using them to control 2 motors. Btw, ROS is installed on a Raspberry Pi with no internet access so it's kind of hard to copy my entire code.
