bug report rosserial arduino

Question

I cannot file a bugreport because I cannot get into Trac, so here it is:

The latest release of rosserial for arduino (downloaded it 30 december) is not capable of subscribing to std_msgs/uint16 or std_msgs/uint8.

I wrote a program to test it. subscribe to and publish the same value. This will not work for uint16, but std_msgs::int16 was okay. The code will compile correctly but on the Arduino it gets misinterpreted (some value is read, which changes also!).

I suspect that the definition of UInt16.h in the std_msgs-directory in Arduino is not okay because it has changed . It used to have definition:

  union {
    signed char real;
    unsigned char base;
  } u_data;

and now not anymore.

But that does not hold because publishing uints with the new version is not a problem!

This looks like a duplicate of https://kforge.ros.org/rosserial/trac/ticket/53

Answer 2

To post to the Trac, you need to create a Kforge account. If you have already created an account and cannot add a bug, let me know so we can get that fixed.

As to the specific bug here, I just patched it in trunk. It will likely take a few days to make it into debs.
