First experience on STM32F4Discovery

I tried to interprete Boards and Pins files in javascript.
Its a new button in WEB IDE, which

1. opens a selectbox for boards
   
2. reads board-info
   
3. reads pins-info according to that
   
4. creates groups of devices
   
5. adds a selectbox for groups of devices
   
6. selecting an item opens a tooltip
   
   

There are more options than on Espruino homepage.
I checked STM32F4Discovery and found CAN and SD ports.
On some pins I found more devices (e.g. PC10,PC11 are uart and usart)
Any idea what I forgot to check ?
