Kevin Cotrone and I will be working on a new version of Opencode, an open source library of standard functions for use in robot programming, and are curious how we could improve our libraries to help with KIPR Link programming. All suggestions are welcome.

I should warn you that if you make it C++, all of the C wrapper functions won't exist. They only work in C. As for additions, Make the CBC / Link movements multiply the speed proportion by BOTH the speed and distance. Currently it is only the speed. Thus one wheel will move longer than the other if the proportions are different. Adding generic line following code would be useful for new teams (using 1 top hat or 2, keeping the tape in between the 2 top hats). Having a function that returns a median / mean filtered analog sensor value would be nice (with varying filter levels). Also, could you make the example code compile? I know the drivelib example doesn't right now.

What do you mean by "they won't exist"? Are you talking about name mangling in C++ programs?

  1. #ifdef __cplusplus
  2. extern "C" {
  3. #endif
  4.  
  5. void this_function_works_in_both_c_and_cpp();
  6.  
  7. #ifdef __cplusplus
  8. }
  9. #endif

I was under the impression that mrp, bmd, analog10, etc only are for C and that you have to use moveRelativePosition, etc instead for C++. Am I mistaken?

You can #include <kovan/kovan.h> manually to get C functions back.
