Spin Stamp

When connecting a TSL230 to the spin stamp is a 1k resistor on vdd acceptable or will it need a 1k on each I/O pin from the chip with nothing on vdd?

Thanks

    You don't need any resistors between the SpinStamp outputs and the TSL230's inputs.
    You should use a 3.3kΩ resistor between the TSL230 output (its pin_6) and the SpinStamp input.

    (I prefer using a voltage divider to avoid the "over-taxing the Propeller clamping diodes dilemma" altogether, but that requires two resistors, or a pot (mon dieu!), and that's asking a lot around here sometimes.)
