[ECOS] Re: How to create a GPIO driver

[EnneGi]

I use this test main:

#include <cyg/infra/diag.h>
#include <cyg/hal/var_io.h>

int main (void)
{

  diag_printf("setting gpio\n");

  cyg_uint32 v_led_ok = CYGHWR_HAL_LPC17XX_PIN_OUT(B,  14, OPENDRAIN, NONE, 
2MHZ); 

    // Turn the LED on 
  CYGHWR_HAL_LPC17XX_GPIO_OUT(v_led_ok, 1); 

    // Turn the LED off 
  CYGHWR_HAL_LPC17XX_GPIO_OUT(v_led_ok, 0);  

  diag_printf("DONE\n");

  while(1)
    {;}

  return 0;

  }


and, when I compile, the compiler give me this error:


gpio.c:9: warning: implicit declaration of function
‘CYGHWR_HAL_LPC17XX_GPIO’
gpio.c:9: error: ‘B’ undeclared (first use in this function)
gpio.c:9: error: (Each undeclared identifier is reported only once
gpio.c:9: error: for each function it appears in.)
gpio.c:9: error: ‘OUT_2MHZ’ undeclared (first use in this function)
gpio.c:9: error: ‘OUT_OPENDRAIN’ undeclared (first use in this function)
make: *** [gpio.o] Error 1


what should I change?

Thanks a lot!
