what happened? thank for any help and advice!
best regard!
Has your user the rights to use the serial port on the laptop? Try sudo chmod 666 /dev/ttyS0 (or whatever your serial port is)
thank you! i sloved the problem by use sudo chmod 666 /dev/ttyUSB0. so it is the permission problem
Hi! I am new for ROS, i am wondering if you could tell/teach me how to create package and why should we do it. THX!
Hi ! I just see the email this weekend,i so sorry for reply too late.If you want to use this package,you just need to
sudo apt-get install ros-indigo-serial.Then you can use serial like in python or c++,just like #include <serial serial.h="">.the serial example
Hi, can you send me the serial example as the link is no longer available?
