im usung adafruit cc3000 wifi shield and all the examples work fine with the shield but for the life of me i can not figure out why it wont initialize atleast in this scketch

oh that might be difficault with shields wouldnt it?? maybe i could leave out the motor shield and set it up myself im only running two small dc motors
so i should change those pins on one of the shields then?
You can't change the pins that the SPI bus is on.
You may be able to change the pins that the motor shield uses, if there are jumpers. The pin numbers in the code need to match the pins that the motors are actually connected to.
merkzilla:
originaly i was but i have just got my mega in the mail and trying to set it up with that.... would this help?
I don't know. The Adafruit CC3000 docs are not complete. I see no schematic. However, I did find this page.
It states you must jumper some pads on the bottom of the shield to use it with a mega. It implies that the CC3000 shield does use D10 to D13 for the shield, and maybe some other pins.
edit: I'll be honest. This is poor design. Almost all new Arduino designs (including the Uno) use the ICSP pins for the SPI bus data lines to avoid this problem. It is very unlike Limor Fried to miss this.
I did jumper the pads already I think it must be a conflict with the motor shield because it works fine with the examples I'll have to look further at the motor shield maybe I'll try it without to see if it connects
D10 to D13 are still unusable after doing the jumper with the pads on the CC3000 shield. That should connect the ICSP SPI data lines to D11 to D13 on the shield.
I'm new to Arduino do you think there's anyway to use both shields?
Sure. Bend the pins on the motor shield that connect to pins 10 to 13. Solder wires on those pins, and connect them to other pins on the Arduino. Change the code to match where you really connected things.
There may be alternatives, depending on which motor shield you have.
merkzilla:
I think I'll stay away from shields in the future.....I'm new to Arduino do you think there's anyway to use both shields?
Maybe. You will need to put the motor shield on top of the CC3000 shield and do some pin bending and wire jumpering as PaulS suggested, then change the defines in the motor shield library.
so it was the motor shield without it im able to connect but it loads the web control page and when i use one of the buttons it cant connect to the page anymore and i have to restart it
