Hi, techie
>From my experience with 2818, I recommend that you do all your
initialization in C, and preferably also all other code, since 2818 is
faster than c50. Take a look at "C281x C/C++ Header Files and
Peripheral Examples" / sprc097 available at TI's site, for examples
initializing and working with peripherals.
