Using Freedom Metal without Freedom E SDK

Hello, I am new with working with the HiFive1 Rev B.

I want to use MultiZone on the board to implement a little smart home device. In order to use the GPIO Pins I tried to use the Freedom Metal library inside of one of the zones, which failed due to different reasons.

  1. Without the rest of the SDK I seem to not be able to trigger any building process for Freedom Metal which means no Machine.h file etc.
  2. When trying to add the missing files, the whole compilation process isn’t working properly since most header files aren’t found afterwards.

Can anybody help me integrating both the MultiZone and the Freedom Metal compilation process? If it’s not possible to use Freedom Metal without the rest, where can I find more information on using the GPIO pins on the board?

Best regards
