Location of platform_pin_function[] array

Hello,

I was putting together a simple demo using the CrossWork Platform Library, and I had to define platform_pin_function[] array in my code, could not find the definition anywhere. I'm using an Olimex STM32-H405 board. I created the project as a CTL sample. It works, but I'm not sure why platform_pin_function[] has to be defined in the app. I'm probably doing something wrong.

Regards,

Jose
