Using a CC3000 breakout

Hello.

I am planning to use the Adafruit CC3000 breakout or the Spakfun CC3000 https://www.sparkfun.com/products/12072 to connect to wifi.

Can I use the libraries that are posted here? Any recommendation or advice?

Thanks a lot

Question relating to:

Last updated: 11 Jul 2014

I had to modify the NVIC_set_all_priorities.h because it seems this version is old and does not contain all mbed platforms (mine is STM32F091) so I wrote

#else
    first_IRQ_number = SysTick_IRQn, // WWDG_IRQn
    last_IRQ_number  = CEC_CAN_IRQn,     
#endif

Now it compiles , but still can not connect to the wireless network. The code gets stucked in the "init" method...

I suspect that the init function (that now is empty) needs to call these functions. But I dont know what should I put in the init function.

Other possibility that I read somewhere is that maybe the CC3000 is not receiving enough power but I doubt it... can it be? (for arduino I used the 5V provided by it and now I am using the 3.3V provided by the STM nucleo)

Please someone help.

It seems some people has gotten this to work... Can anybody help me?

So far I have identified that the program gets stucked in the start() function of the CC3000_wlan class. Specifically in the part in which the STM32 waits for the IRQ from the CC3000

 if (spi_irq_state) {
        // wait till the IRQ line goes low
        while(_spi.wlan_irq_read() != 0);
    }

It seems that the IRQ never comes therefore the program gets stucked.

I wonder what is the problem... Please help

Nobody can help me? I have run out of ideas to solve the problem I even stopped using a breadboard and connect this through soldering a board. But still it can not get connected. Any help will be greatly appreciated
