During the week a package arrived from Seeedstudio with a Grove Base Hat for RPI Zero. So I have modified my Grove Base Hat for RPI Windows 10 IoT Core library to add support for the new shield.
The Raspberry PI Zero hat has a two less analog ports and a different device id so some conditional compile options were necessary
namespace devMobile.Windows10IoTCore.GroveBaseHatRPI
{
#if (!GROVE_BASE_HAT_RPI && !GROVE_BASE_HAT_RPI_ZERO)
#error Library must have at least one of GROVE_BASE_HAT_RPI or GROVE_BASE_HAT_RPI_ZERO defined
#endif
#if (GROVE_BASE_HAT_RPI && GROVE_BASE_HAT_RPI_ZERO)
#error Library must have at most one of GROVE_BASE_HAT_RPI or GROVE_BASE_HAT_RPI_ZERO defined
#endif

A3 = 3,

};
The code updates have been “smoke” tested and I have updated the GitHub repository.
