i am having some issues with my ADA fruit CC3000 i have wired as per the documentation and i am getting nothing it does not seem to want to communicate with the device.
i have a mega 2560
as per the documentation
http://learn.adafruit.com/adafruit-cc3000-wifi/cc3000-breakout
CLK to Digital 52
MISO to Digital 50
MOSI to Digital 51
CS to Digital 10
VBEN to Digital 5
IRQ to Digital 3
5v and ground

but i am not getting the card to get past the "Initialising the CC3000"

any ideas will be great should i be trying a software SPI?

never mind it was just a wiring issue
