    Galileo Gen 1 SCL PIN has no signal

    GalileoUser

      Hello,

      I have been trying to trouble shoot why my SPI connection to another device is not working. I am using the Arduino library SPI and I am trying to connect to a RA8875 (RA8875 Driver Board for 40-pin TFT Touch Displays - 800x480 Max ID: 1590 - $34.95 : Adafruit Industries, Unique & fun DI…)  from Adafruit.

       

      The issue I am having is that of the SPI pins SCL pin and the pin 3 on the ICSP do not have the SPI clock signal coming from it. When I connect the oscilloscope I can see the signal on the other SPI pins but not the clock.

       

      Does anyone have any idea what I missed to prevent the clock signal from showing up.

       

      Thanks for the help.
