I have the Shield Shield and I am trying to drive the DotStar LED Strip via hardware SPI. Circuit works great with a normal Arduino but it does not work with the shield. Tried the software SPI too with shield pins 4 and 7 as clk and data with the photons pin 3 and 4 translating to that. Also tried slowing down the hardware spi to the system clock divided by 16. Using the DotStar here:
I saw on the forums about the Shield having an oscillation issue. Any way to get around this?
