Working Code for CC3000 and Nucleo F030R8?

Hello,

Does anyone have some working sample code for getting a CC3000 (adafruit breakout board) working with a Nucleo board (STM32F030R8)?

I just need some sample code to do a simple GET request. I've tried some of Martin's http_client code, but can't seem to get it to work. I'm trying to figure out what settings to use in the init() file, and also to figure out what pins to connect. I think I have the SPI pins right, but which pins can I use on the nucleo board for the IRQ?

I'm fairly new to mbed and ARM, so any help would be appreciated. I just want to get a sample code going and then I can mess around with it.

Thank you!

Edit:

Ok, I've imported Martin Kojtal's CC3000_websocket_demo program and I've put the following in the pin definition section (in main.cpp):

/* cc3000 module declaration specific for user's board. Check also init() */
#if (MY_BOARD == WIGO)
cc3000 wifi(PTA16, PTA13, PTD0, SPI(PTD2, PTD3, PTC5), "ssid", "key", WPA2, false);
Serial pc(USBTX, USBRX);
#elif (MY_BOARD == WIFI_DIPCORTEX)
cc3000 wifi(p28, p27, p30, SPI(p21, p14, p37), "ssid", "key", WPA2, false);
Serial pc(UART_TX, UART_RX);
#elif (MY_BOARD == MBED_BOARD_EXAMPLE)
cc3000 wifi(p9, p10, p8, SPI(p5, p6, p7), "ssid", "key", WPA2, false);
Serial pc(USBTX, USBRX);
#else
cc3000 wifi(PB_3, PB_4, PB_6, SPI(PA_7, PA_6, PA_5), "MySSID", "MyPass", WPA2, false);  //irq, en, cs, spi(MOSI, MISO, SCK), irq-port
Serial pc(PA_2, PA_3); // tx, rx


#endif

Above, I'm assuming that since I define my board as "UNDEFINED" in the main.h file, it will go to the #else condition...

My main.h file has the following:

#ifndef MAIN_H
#define MAIN_H

#define WIGO               1
#define WIFI_DIPCORTEX     2
#define MBED_BOARD_EXAMPLE 3
#define UNDEFINED          4

#define MY_BOARD UNDEFINED

void init();

#endif

Assuming this is defined correctly, what else do I need to change in the Init() function for this to work with nucleo F401RE/F030R8 boards?

btw, if I compile the code with the above changes, I get the following errors:

1) Identifier "first_IRQ_number" is undefined "for(irqnum = first_IRQ_number ; irqnum < last_IRQ_number + 1; irqnum++)"

Do I need to define the first_IRQ_number and last_IRQ_number somewhere? Do I need to do anything in the NVIC_set_all_priorities files?

Thanks so much for the help!
