Thanks a lot! I got it!
1. And could you please send me a flexcan example of mpc5674f,.
Now I got one, but it doesn't work. The following is the example I downloaded from the Community,
2. And also, when I generated C code of 5674f using RAppID ,and compiled, a error arised, it said cannot open prefix file vle_macro.txt.
In the settings, I added the vle_macro.txt as the "Using-RAppID-with-codewarror.pdf" requested.
