CheckSum does not match. #272

Closed jhbirdchoi closed 3 years ago

jhbirdchoi commented 3 years ago

Hi

I am using the noetic version of ros1.

If I use an image that has already been built, there is no problem.

$ export OPENCR_PORT=/dev/ttyACM0 $ export OPENCR_MODEL=burger_noetic $ wget https://github.com/ROBOTIS-GIT/OpenCR-Binaries/raw/master/turtlebot3/ROS1/latest/opencr_update.tar.bz2 $ tar -xvf opencr_update.tar.bz2 (Fw version : 1.2.6)

But when I build and use opencr on arduino, I have a problem. The following error log is displayed. "Creation of publisher Failed : Checksum does not match"

Which version of opencr should I use? (at Arduino board manager)

thanks

Hi @jhbirdchoi I'm sorry about the confusion. Since Noetic, battery status message has been updated and requires a new library. This fix has been applied to the Arduino example, but need to uncomment the NOETIC_SUPPORT definition in turtlebot3_core_config.h file.

  1. Open the TurtleBot3 firmware. Depending on your platform, please select the correct firmware. Burger : File > Examples > turtlebot3 > turtlebot3_burger > turtlebot3_core Waffle/Waffle Pi : File > Examples > turtlebot3 > turtlebot3_waffle > turtlebot3_core
  2. Open the turtlebot3_core_config.h and uncomment the NOETIC_SUPPORT defintion in the line 21.
  3. Connect OpenCR to the PC and Select OpenCR > OpenCR Board from Tools > Board menu.
  4. Select the OpenCR connected USB port from Tools > Port menu.
  5. Upload the TurtleBot3 firmware sketch with Ctrl + U or the upload icon.

Above information is described in https://emanual.robotis.com/docs/en/platform/turtlebot3/opencr_setup/#opencr-setup Noetic document. The content is folded by default and can be expanded by clicking on the expandable note. image
