library for C++ CANOpen implementation. mbed independant, but is easy to attach into with mbed.
Dependents: ppCANOpen_Example DISCO-F746NG_rtos_test
Example:
Import programppCANOpen_Example
I am no longer actively working on the ppCANOpen library, however, I want to publish this project so that anyone who wants to pick up any of the pieces can have a good example. This is a a project I was working on using the ppCANOpen library. It has a pretty in deep use of the object dictionary structure. And a number of functions to control high voltage pinball drivers, if you're into that sort of thing.
