Having trouble writing data via I2C.
I thought maybe the problem was with the PCA9956B LED driver we're evaluating but just to be sure, I scoped the SDA and SCL pins and they never go low for a start condition.
i2C0 <- I2C(0);
i2C0.write8(1, 0); -- Halts here with error: %%Runtime error [I2C write error]
I'm using 2.2Kohm pullups on both lines and the documentation looks like instantiating I2C overrides the GPIO use of the port.
