[Discuss-gnuradio] E100 - Interface between OMAP3 and FPGA

Dear all,

I need to send data from the OMAP3 to the Spartan3an FPGA. As I understand ,from the wiki and presentations,  there are two ways to communicate namely; using setting_reg and GPIO.  The second way seems easier so I'll try it first. 

I intend to set or clear the free GPIOS on the Spartan FPGA such as over_gpio_22. I  added the following code to the example tx_waveforms.cpp. 

        static struct gpio gpio_test = { 22, GPIOF_OUT_INIT_LOW, "OVERO_GPIO_22" };
//set gpio22 which is connected to pin IO_L30N_0

I tried to compile then I got the error that can't find GPIO.h. 

My question: did I use the correct high level function or I used a "lower level" that is used to implement the function?
