STEVAL-MKI109V3 is a motherboard for ST MEMS adapters.
The Unico-GUI can be used to show data coming from the adapter board (e.g. STEVAL-MKI172V1) when the motherboard has been programmed with a dedicated firmware.
For the case STEVAL-MKI109V3 + STEVAL-MKI172V1, angle and heading data computation is done at software level in the Unico-GUI.
To control other different peripherals, you may need a dedicated firmware or hardware.
