Does anyone know of a .NET library for the Scroll pHat?

I’m interested in using my Scroll pHat with Windows IoT on my Raspberry Pi 2. I suppose I could work to create my own library to do this but I’d much rather use an existing one if possible.
Thanks!

None exist that I’m aware of, and I’d be surprised if a library did!

There are, however, plenty of I2C examples which would help get you started. I was able to successfully drive a PiGlow from Windows IoT; the chip used on Scroll pHAT isn’t much more complicated.

You can either look at the datasheet for the driver chip, or follow the code in the Python library to get an idea of how it should work.

MODE_5X11 = 0b00000011

class I2cConstants:
    def __init__(self):
        self.I2C_ADDR = 0x60
        self.CMD_SET_MODE = 0x00
        self.CMD_SET_BRIGHTNESS = 0x19
        self.MODE_5X11 = 0b00000011

class IS31FL3730:
    def __init__(self, smbus, font):
        self.bus = smbus
        self.font = font
        self.i2cConstants = I2cConstants()
        self._rotate = False

        self.bus = self.bus.SMBus(1)
        self.buffer = [0] * 11
        self.offset = 0
        self.error_count = 0
