Arduino Micro and CC3000 Issue

[snowsparky]

I'm a novice to the Arduino. I've done a little reading however after lots of combinations of wiring I haven't made any progress.

The article "Mixed feedback for support on the Arduino Micro and the Adafruit CC3000" on http://forums.adafruit.com/viewtopic.php?f=22&t=49231 discusses the required pinout as:

IRQ->D10 on the Micro
VBEN->D5 on the Micro
CS->D3 on the Micro
MOSI->ICSP4 on the Micro
MISO->ICSP1 on the Micro
CLK-> D13 on the Micro
VIN-> 5V on the Micro
GND-> GND on the Micro

however the buildtest example code is

Code: Select all

// These are the interrupt and control pins
#define ADAFRUIT_CC3000_IRQ   3  // MUST be an interrupt pin!
// These can be any two pins
#define ADAFRUIT_CC3000_VBAT  5
#define ADAFRUIT_CC3000_CS    10

so I've switched the IRQ and CS pins over
IRQ->D3 on the Micro
VBEN->D5 on the Micro
CS->D10 on the Micro
MOSI->ICSP4 on the Micro
MISO->ICSP1 on the Micro
CLK-> ICSP3 on the Micro
VIN-> 5V on the Micro
GND-> GND on the Micro

I also believe that the ICSP is connected on the Micro to the MOSI, MISO and SCK pins so the alternative wiring given next should also work.
IRQ->D3 on the Micro
VBEN->D5 on the Micro
CS->D10 on the Micro
MOSI->MOSI on the Micro
MISO->MISO on the Micro
CLK-> SCK on the Micro
VIN-> 5V on the Micro
GND-> GND on the Micro

However for all configurations I get

Code: Select all

Hello, CC3000!

RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 1817


Initializing the CC3000 ...

Are there any solder jumps, rebuilds of libraries or power requirements that I may be missing?

If you are powering your micro through the USB port try using a powered hub as some computers can't supply enough power through the ports to satisfy the CC3000.
