build sdk image to program in c++

Dear bergmanu,

I'am starting to play with iot 2050 (1YA2), I follow the SIMATIC_IOT2050_Setting_up_V1.0.pdf without problems. Now I want to complete  "Install_Eclipse_SDK_Linux_V1.0.pdf" I download the github project meta-iot2050 and I'm trying to build sdk image to program in c++.

I have a question:

- Where I can find (if exists) the mapping and the datailed description for all the integrated IO (i.e. user led is mapped to /sys/class/Leds ) and for other interfaces (i.e. iot2000 IO shield)?

- Is there a library (c++) inside iot image to interface with GPIO?

Thank you for your help

ATB
